Description
Translated fromChinese技术领域technical field
本发明涉及硬件安全领域，特别涉及一种基于硬件编号和时间戳的设备授权方法及系统。The invention relates to the field of hardware security, in particular to a device authorization method and system based on hardware number and time stamp.
背景技术Background technique
随着经济的发展，中小型企业不断增多，很多企业都拥有自己的商业化产品。商业化产品需要进行授权才能继续使用，是目前保证企业利益的有效手段。With the development of the economy, the number of small and medium-sized enterprises continues to increase, and many enterprises have their own commercial products. Commercial products require authorization before they can continue to be used, which is an effective means to ensure the interests of enterprises at present.
目前市面上授权方式大致分为三种：联网类软件产品的会员制、非联网类软件产品的授权码以及设备交付性产品的授权文件At present, the authorization methods on the market are roughly divided into three types: membership system for networking software products, authorization codes for non-networking software products, and authorization documents for equipment-delivered products
会员制产品多依赖于网络，授权信息存储在服务端，离线环境下无法继续使用。Membership products mostly rely on the network, and the authorization information is stored on the server, which cannot be used in an offline environment.
以授权码方式进行授权的商用软件产品，因为无法和设备完全绑定，往往存在“一码多用”的情况，很容易被盗用，所以现在网上可以搜到各类软件产品的激活码。Commercial software products that are authorized by means of authorization codes cannot be completely bound to the device, so there is often a situation of "multiple use of one code", which is easy to be stolen. Therefore, activation codes for various software products can now be found on the Internet.
对于大型的设备交付性产品，因为交付的是设备，所以可以有效的和设备绑定，但多采用授权文件的方式进行授权，对于一些重视安全防控的企业来说，授权文件的上传需要经历多次拷贝，甚至需要上级审批，流程繁琐，耗费时间。For large-scale equipment delivery products, because the equipment is delivered, it can be effectively bound to the equipment, but authorization is usually performed by means of authorization files. For some enterprises that attach importance to security prevention and control, the uploading of authorization files requires experience Multiple copies, even need approval from superiors, the process is cumbersome and time-consuming.

本授权方法的目的是提供一种方便企业运维人员对设备进行授权和延期授权的方式。同时对于设备提供方，保证了授权码的安全性和唯一性，保证授权码不被篡改，在其它设备不被复用。具体地，请参考图1，其示出了本申请实施例提供的一种基于硬件编号和时间戳的设备授权方法的流程图，该方法可以包括以下步骤：The purpose of this authorization method is to provide a convenient way for enterprise operation and maintenance personnel to authorize and extend authorization for devices. At the same time, for the device provider, the security and uniqueness of the authorization code are guaranteed, and the authorization code is not tampered with or reused in other devices. Specifically, please refer to FIG. 1, which shows a flowchart of a device authorization method based on a hardware number and a time stamp provided by an embodiment of the present application. The method may include the following steps:
步骤101，通过目标设备管理平台获取目标设备编号，并通过目标设备编号生成设备序列号。In
在本申请实施例中，步骤101主要是基于硬件编号生成唯一序列号，具体地获取设备网卡MAC地址、主板序列号、CPU序列号、磁盘序列号，组合并打乱顺序，通过自定义算法生成设备序列号，在本申请实施例中设备序列号为10位的数字。In the embodiment of the present application,
步骤102，基于设备序列号生成初始授权码。
其中，初始授权码还包括授权类型信息、授权时间信息、签名信息以及数据校验码信息，可以将以上信息放在25位的授权码中，要保证其可读性，不能为纯数字，其中，20位数字表示授权类型信息、授权时间信息、签名信息，5位数字表示数据校验码信息。Among them, the initial authorization code also includes authorization type information, authorization time information, signature information and data verification code information. The above information can be placed in a 25-digit authorization code. To ensure its readability, it cannot be a pure number. , 20 digits represent authorization type information, authorization time information, signature information, and 5 digits represent data check code information.
在本申请可选的一种实施例，可以将时间戳前两位按16进制转换为字母，增加解密复杂度，压缩授权码空间。In an optional embodiment of the present application, the first two digits of the timestamp may be converted into letters in hexadecimal to increase the decryption complexity and compress the authorization code space.
具体地：时间戳前两位，因为时间戳前两位目前都是16开头，比如2022年5月15日对应的时间戳为1652590000，则前两位为“16”，假设自定义映射表“16”对应的F，则直接可用F表示，这样2压缩了1位可以去做授权类型。Specifically: the first two digits of the timestamp, because the first two digits of the timestamp currently start with 16, for example, the timestamp corresponding to May 15, 2022 is 1652590000, then the first two digits are "16", assuming a custom mapping table " The F corresponding to 16" can be directly represented by F, so that 2 compressed 1 bit can be used as the authorization type.
例如：E.g:
时间戳：1652590000Timestamp: 1652590000
机器码：1025965741Machine code: 1025965741
授权类型：时间授权＝1Grant Type: Time Grant=1
按顺序拼接则为165259000010259657411，Splicing in order is 165259000010259657411,
以上21位的数字，数据部分就超出了预期，所以结合时间戳的特征，对其前两位进行了压缩，真实参与加密的是F5259000010259657411。其中，16位真实映射的值是根据种子进行变化的，不同的种子，生成的值不一致。另外，这也是后续将授权码进一步压缩为20位甚至10位进行优化的一个思路。For the above 21-digit numbers, the data part is beyond expectations, so combined with the characteristics of the timestamp, the first two digits are compressed, and the actual encryption is F5259000010259657411. Among them, the value of the 16-bit real mapping is changed according to the seed, and the generated values are inconsistent with different seeds. In addition, this is also an idea to further compress the authorization code into 20 or even 10 digits for optimization.
在本申请可选的一种实施例，包括自定义映射表，将需要授权的信息拼接后，逐位按映射表进行匹配翻译，避免纯数字的情况。In an optional embodiment of the present application, a custom mapping table is included. After splicing the information that needs to be authorized, matching and translation are performed bit by bit according to the mapping table, so as to avoid the situation of pure numbers.
步骤103，将初始授权码等分为多组子授权码，并对多组子授权码进行加密的目标授权码。
其中，对多组子授权码进行加密包括设置自定义种子作为加密密钥对第一组子授权码进行加密，并基于前一组子授权码的加密结果对后一组子授权码进行加密。Wherein, encrypting multiple groups of sub-authorization codes includes setting a custom seed as an encryption key to encrypt the first group of sub-authorization codes, and encrypting the latter group of sub-authorization codes based on the encryption result of the former group of sub-authorization codes.
在本申请实施例中，将初始授权码等分为多组子授权码，即将将初始拼接生成的授权码拆分为5部分，其中，第一部分以自定义种子为加密密钥，其余每一块数据使用上一块加密的结果作为加密密钥，相当于5块数据分别使用了5种不同的加密密钥。In the embodiment of the present application, the initial authorization code is divided into multiple groups of sub-authorization codes, that is, the authorization code generated by initial splicing is divided into 5 parts, wherein the first part uses the custom seed as the encryption key, and each other The data uses the result of the previous block of encryption as the encryption key, which is equivalent to using 5 different encryption keys for each of the 5 blocks of data.
例如，格式可以为XXXXX-BBBBB-CCCCC-DDDDD-AAAAA，这种格式也是为了方便授权人员去观察和输入的。For example, the format can be XXXXX-BBBBB-CCCCC-DDDDD-AAAAA, which is also for the convenience of authorized personnel to observe and input.
在本申请实施例中，在步骤103之后还包括：In this embodiment of the present application, after
基于所述目标授权码对目标设备进行授权，并通过后台校验目标授权码；并对目标设备的授权结果进行反馈。The target device is authorized based on the target authorization code, and the target authorization code is verified through the background; and the authorization result of the target device is fed back.
授权码的20位作为数据部分，5位为数据校验部分。且数据部分和校验码部分，再增加一层加密处理。修改授权码的任何一位，都会导致校验失败；且保证了生成授权码时，任何有效信息的细微调整(如时间戳增加1秒)，生成的授权码发生巨大差异，使破解时无规律可循。The 20 digits of the authorization code are used as the data part, and the 5 digits are used as the data verification part. And the data part and the check code part, an additional layer of encryption processing is added. Modifying any bit of the authorization code will cause the verification to fail; and it is guaranteed that when the authorization code is generated, any slight adjustment of any valid information (such as adding 1 second to the timestamp) will result in a huge difference in the generated authorization code, making the cracking irregular. Followable.
如图2，给出了利用本方法的授权整体流程，本授权方法基于10位的数字设备序列号，以及时间戳，可对厂商设备中运行的软件进行时间授权。具体包括：Figure 2 shows the overall authorization flow using this method. Based on the 10-digit serial number of the digital device and the time stamp, the authorization method can perform time authorization on the software running in the manufacturer's equipment. Specifically include:
(1)设备上架，运维访问管理平台获取机器码；(1) The equipment is put on the shelf, and the operation and maintenance access management platform to obtain the machine code;
(2)向厂商提供机器码；(2) Provide the machine code to the manufacturer;

在本申请一个可选的实施例中，系统200还包括：In an optional embodiment of the present application, the
校验模块204，用于基于目标授权码对目标设备进行授权，并通过后台校验目标授权码；并对目标设备的授权结果进行反馈。The verification module 204 is configured to authorize the target device based on the target authorization code, verify the target authorization code through the background, and feed back the authorization result of the target device.
