The computer uses the configuration information to configure the wireless station. The method also provides a way to limit access to the configuration information through the use of encryption and limiting the number of times the configuration information is retrieved. The method is also an effective way to distribute security keys for encryption systems whose purpose is to secure communications in a wireless network.

Description

CROSS REFERENCE TO RELATED APPLICATIONS
• This application is a Divisional of and claims priority under 35 U.S.C. Section 121 to U.S. patent application Ser. No. 10/000,982, filed on Oct. 24, 2001 and entitled “Method for Physically Updating Configuration Information for Devices in a Wireless Network” by Zeijko John Serceki et al.
FIELD OF THE INVENTION
• This invention relates generally to wireless networks, and particularly to exchanging configuration information of wireless networks using a physical medium for the data transfer.
BACKGROUND OF THE INVENTION
• Wireless networks provide a high level of convenience for their users. Once the wireless networks are properly configured, users can roam freely within the coverage area of the wireless network without being encumbered by network connections. Additionally, installation of wireless networks does not require extensive drops of expensive network cabling.
• However, configuring and installing a wireless network is not necessarily a simple task. Because the communications medium for a wireless network is typically “air”, communications from multiple wireless networks may be present on the communications medium simultaneously within a given location. Unique network identifiers are used to distinguish transmissions from one wireless network over another. A typical installation scenario may require that the installer manually input the unique network identifier into the installation program, along with other required information, such as client address, client name, network address, network name, etc. Manual data entry of this extensive list of information is at the very least tedious and error prone. Manual data entry also limits the number of installations that can be performed in a day. Compare this to the installation of a typical wired network, where configuration and installation has become as simple as plugging an active network drop into a network interface card installed on a computer and having the computer automatically adding itself to the network and configuring itself.
• One solution to the installation problem involves the use of a set of default values. Through the use of default values, wireless networks can automatically configure themselves during the initially power-on after the components have been installed. However, default values do not work very well when there are multiple wireless networks of the same type operating in a given location, due to transmission conflicts between the networks and the confusion that results. Additionally, default values present security issues that are open to exploitation by anyone who knows of their use. For example, a disgruntled employee with knowledge of the default values may simply park his car outside of the business location and turn his computer and is given full access of the business' computer system.
• Another problem facing wireless networks is the inherent insecurity of their transmissions. A motivated person with electronic surveillance equipment can capture the transmissions and can obtain access to the information in the transmissions. A solution provided for securing communications on a wireless network is to use a built-in security/encryption mechanism, such as Wired Equivalent Privacy (WEP) used in IEEE 802.11 wireless local area networks. However, WEP and many other security mechanisms require that security keys be manually inputted during installation or updates. This leads to distribution of the security keys via electronic mails with the security keys included in them, or the security keys are written down on pieces of paper. Such unsecured methods of security key distribution severely weakens the security system because persons not authorized for access to the security keys may be able to obtain the keys, often times by simply taking a piece of paper out of a waste-paper basket.
• A need has therefore arisen for a method to provide easy exchange of configuration information and at the same time, provide a measure of security for the information.
SUMMARY OF THE INVENTION
• The preferred embodiment of the invention provides a way to distribute configuration information to wireless stations via the use of a device that stores the configuration information in memory. When a user is provided the device, he/she can connect it to a computer that is connected to the wireless station and the computer will read out the configuration information and configure the wireless station so that it will be able to operate in a wireless network. The device can also be used to distribute encryption keys for the wireless network, along with whatever information deemed important.
• In one aspect, the present invention provides a method for physically exchanging configuration information and/or encryption keys in a wireless network for use in configuring wireless station comprising saving the configuration information and/or encryption keys onto a physical device, coupling the physical device to a wireless station, initiating the download of the information stored on the physical device and using the configuration information to configure the wireless station that is coupled to the digital device.
• The present invention provides a number of advantages. For example, use of the preferred embodiment reduces the change of errors by electronic distribution of configuration. Because of this, the manual entry of complex information is not required, thus reducing the chance of errors.
• Also, because the methods are simple, security information is more likely to be updated frequently. Other methods that are tedious and/or cumbersome are likely to be neglected.
• Aspects of the present invention that utilizes electronic transfer of configuration information have the advantage that a layer of security can be added to the configuration and security information. This additional layer of security helps prevent unauthorized users from obtaining access to the information.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
• The making and use of the various embodiments are discussed below in detail. However, it should be appreciated that the present invention provides many applicable inventive concepts which can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.
• Networks adhering to the IEEE 802.11 technical standard and its more advanced version, IEEE 802.11b, are among the most widely available wireless networks today. The IEEE 802.11b wireless network operates in the 2.4 GHz Industrial, Scientific, and Medial (ISM) radio frequency (RF) spectrum band and provides up to 11 Mbps of data transfer rate. The IEEE 802.11 wireless network is specified in a technical standard document, “ANSI/IEEE Std 802.11, 1999 Edition; Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements. Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications,” which is incorporated herein by reference. The IEEE 802.11b wireless network is specified in a supplement to the IEEE 802.11 technical standard, “IEEE Std 802.11b-1999 (Supplement to ANSI/IEEE Std 802.11, 1999 Edition) Supplement to IEEE Standard for Information technology—Telecommunications and information exchange between systems—Local and metropolitan area networks—Specific requirements—Part 11: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Higher-Speed Physical Layer Extension in the 2.4 GHz Band” which is also incorporated herein by reference.
• For discussion purposes, the focus of this specification is mainly on wireless communications networks that are adherent to the IEEE 802.11 technical standard and uses personal computers. However, the ideas presented in the preferred embodiments of the present invention have applicability in other networks where a client must be configured with various pieces of configuration information before they can begin operation. Therefore, the present invention should not be construed as being limited to only IEEE 802.11 wireless networks. Examples of such networks include HomeRF, Hiperlan, and other wireless networks that require a client be configured with information or be updated periodically with security information.
• Referring now toFIG. 1, a diagram (prior art) of a typical wireless network configuration according to the 802.11 technical standard. Note thatFIG. 1 displays one possible configuration of an 802.11 wireless network out of the many different configurations that are possible.FIG. 1 illustrates a wireless network100 comprising anaccess point110 that is wirelessly connected to a firstwireless station120 and a secondwireless station130. Theaccess point110 can be viewed as a controller of communications taking place within the wireless network100.
• Prior to use, a wireless station should be configured with a unique network identifier that is used to identify communications within the wireless network. All communications within a wireless network controlled by theaccess point110 are so labeled so that other access points and wireless stations will be able to identify the origination of such communications. In addition, other configuration information such as device addresses, device names, network addresses, network names, domain names, subnet masks, etc. are required for the proper integration of the wireless station into the existing wireless network.
• If the wireless network uses an encryption mechanism, such as Wired Equivalent Privacy (WEP) in an IEEE 802.11 wireless network, to help increase security in the network, then the security keys should also be entered during the installation process. Security keys are typically long, random strings of alphanumeric characters, making them very difficult to remember and to accurately enter. Such security keys are usually distributed by emails, written down on pieces of paper, or known only to authorized personnel. Distribution by email or pieces of paper is very insecure since emails are easily intercepted and paper can be readily retrieved from trash bins. If the security keys are limited to only a small number of people, then the installation of new wireless stations is limited to how many stations these trusted people can attend to.
• Such distribution methods also make it very difficult to update the configuration information and the security keys, since it takes so long to perform the changes. The inertia and inherent inefficiencies in the system make it very easy to neglect updating the security keys, therefore, jeopardizing the security of the wireless network.
• Rather than requiring the installer to enter all of this information or having an information systems support staff member perform all of the installations, the configuration information may be stored on a device that can be passed around to various users who are installing wireless stations. The user would then only need to install the hardware portion of the wireless station and when prompted for configuration information, connect the device to the personal computer or the wireless station and the configuration information would be automatically provided to the installation software, negating manual entry of the configuration information. Alternatively, after installing the hardware portion of the wireless station, the user can connect the device to the personal computer or the wireless station and the software installation initiates automatically upon detection of the connection of the device.
• Referring now toFIG. 2, a diagram illustrates adevice200 for use in physically exchanging network configuration information in a wireless network according to a preferred embodiment of the present invention. Thedevice200 comprises astorage unit210 and aconnector215. Acable220 connects thestorage unit210 to theconnector215. Additional glue logic and interface logic for providing interoperability between thedevice200 and the personal computer that thedevice200 connects to is not shown inFIG. 2. It is understood, however, that such logic is typically necessary for proper functionality of thedevice200 and the present invention.
• Thestorage unit210 comprises amemory225 and optionally, aprocessor230. Thememory225 is used for storing the configuration information and the security keys and any other type of information deemed necessary. Theprocessor230 can be used to provide an encryption function to thedevice200 to help protect the contents of thedevice200. Additionally, theprocessor230 can be used to limit access to certain specified users and wireless stations or theprocessor230 can limit the number of times the configuration is retrieved from thedevice200. If theprocessor230 is not present in the device, then some of the added functionality such as encryption and access control are not available, unless the installation/update software executing on the personal computer supports the added functionality and performs the functionality. However, if the encryption and access control is performed by the installation/update software, then the level of security provided is not as high as if they were performed by theprocessor230.
• According to a preferred embodiment of the present invention, the configuration information may be downloaded (or programmed onto) thedevice200 by a device programmer (not shown). The device programmer would be able to couple to thedevice200 via a preferred connection mechanism, typically, the same connection mechanism (the connector215) that is used to couple thedevice200 to the personal computer. Once thedevice200 is coupled to the device programmer, the configuration information and/or encryption keys and any other type of information can be downloaded onto thedevice200. The device programmer may be a computer (or some other digital device) used by an installer or a network administrator.
• According to a preferred embodiment of the present invention, theconnector215 is preferably a Universal Serial Bus (USB) connector. However, any other type of connector that can provide connectivity and exchange of information between a personal computer and thedevice200 is also operable. Other examples of connectors include, but are not limited to: IEEE 1394 (FireWire), serial data connectors, parallel data connectors, Apple Desktop Bus (ADB) connectors, Small Computer System Interface (SCSI) connectors, etc.
• According to another preferred embodiment of the present invention, theconnector215 and thecable220 are replaced by a wireless connection. The wireless connection would negate the need to use physical connectors to connect thedevice200 to a personal computer. Theconnector215 and thecable220 are replaced by a wireless transmitter and receiver pair, the pair is commonly referred to as a transceiver. Examples of wireless connections include, but are not limited to: radio frequency (RF), infrared, laser light emitting diodes, laser, microwave, etc.
• Referring now toFIG. 3, a diagram illustrates adevice300 for physically exchanging configuration information in a wireless network according to a preferred embodiment of the present invention. Internally,device300 is similar to device200 (FIG. 2) in that it has amemory325 for storing information and a processor330 (optional) for providing additional functionality support. However, rather than connecting to a personal computer via a cable or wireless connection, thedevice300 features aspecial connector315 that adheres to a common computer interface specification. For example, theconnector315 may be a PC Card interface connector (formerly known as PCMCIA), any one of the many memory storage device interfaces, such as Memory Stick, SanDisk, Compact Flash, CF Flash, Smart Media, Secure Digital, MultiMedia Card (MMC), NAND Flash, etc., or a proprietary memory interface.
• Referring now toFIG. 4, a flow diagram400 displays a sequence of steps involved in changing a set of security keys for a wireless network according to a preferred embodiment of the present invention.FIG. 4 displays the sequence of steps under the assumption that wireless stations in the wireless network are already properly configured and operational. Thesequence400 begins when a network administrator decides to change the security (WEP) keys for the wireless network (410). Depending on internal policies, the network administrator may be required to change the security keys at regular intervals or after detecting a security breach. Regardless of the case, the new security keys and other wireless network information are stored onto the device (420). As discussed previously, the information written to the device may be encrypted or encoded to reduce illicit distribution.
• According to a preferred embodiment of the present invention, the network administrator may create a plurality of the devices to speed the distribution of the new security keys. After the network administrator creates the devices, the devices are distributed to users who need them (430). The user then simply inserts the device into a corresponding access port (440) on his/her personal computer. A preferred access method is through the personal computer's USB port, though, as discussed previously, there are many different ways of interfacing the device to the personal computer.
• With the device connected to the personal computer, the personal computer is able to detect the presence of the device (450). Autodetection is a function of the particular type of access port used. For example, more advanced ports such as USB and IEEE 1394 ports can automatically detect a new device being connected to them. However, older legacy ports such as the standard serial and parallel ports cannot. According to another embodiment of the present invention, if the device interfaces to the personal computer through a port that does not support automatic detection of devices being connected to it, then the user is required to perform an additional step of executing a program that will initiate the data exchange sequence. This may be achieved by selecting the program to execute or by pressing a designated button on the personal computer or entering a particular key sequence on the personal computer's keypad.
• However, if the port supports automatic detection of devices connected to it, then the personal computer will be able to detect the insertion of the device (450) and it will automatically execute a program designed to retrieve the information stored in the device. According to another preferred embodiment of the present invention, the device is linked to a single user and computer and access control will verify if the device is connected to the authorized computer before permitting the personal computer to retrieve the contents. As discussed previously, encryption and access control can be performed by a processor located inside the device or it may be performed by the installation/update software executing on the personal computer.
• According to another preferred embodiment of the present invention, the configuration information on the device may be retrieved only one time (or a specified number of retrievals) and the device will allow only a single retrieval (or up to the specified number of retrievals) of the information stored on it. Any attempts at retrieving the information when the number of accesses has exceeded the allowed limit will fail.
• After retrieving the information, the personal computer uses the information to configure the wireless station connected to the personal computer (460) and the personal computer resumes operation, using the newly supplied network information (470). The user can then return the device to the network administrator or pass it onto other users of the wireless network (480).
• Referring now toFIGS. 5a-d,diagrams illustrate different embodiments of the present invention.FIG. 5adisplays a preferred embodiment of the present invention, wherein apersonal computer505 is coupled to awireless station507.FIG. 5adisplays thewireless station507 as being external to thepersonal computer505.

Adevice509 that contains configuration information interfaces to thepersonal computer505 through aninterface slot511. Theinterface slot511 can be, but is not limited to: a PC Card interface (formerly known as a PCMCIA interface), a memory storage device interface, such as Memory Stick, Compact Flash, CF Flash, SanDisk, Smart Media, Secure Digital, MultiMedia Card (MMC), NAND Flash, etc., or some proprietary memory interface built into thepersonal computer505.

Rather than requiring thepersonal computer535 possess a compatible connection, there is adocking station539, to which thepersonal computer535 may connect. There is some connectivity provided between thepersonal computer535 and thedocking station539 through the use of a connector(s)541. Also coupled to the docking station is anetwork543. The connection between thedocking station539 and thenetwork543 may be via one of many various types of network connections, such as a direct-connect local area network connection, a high-speed digital connections such as a digital subscriber line or a cable modem line, a dial-up modem connection, or even a high-speed wireless connection.
