本发明涉及射频识别技术领域，尤其涉及超高频无源电子标签灭活方法及装置。The invention relates to the technical field of radio frequency identification, in particular to a method and device for inactivating an ultra-high frequency passive electronic tag.
背景技术Background technique
在射频识别领域，超高频无源电子标签(下称电子标签)通过天线接收电磁场能量，给芯片供电。电子标签在生命周期结束时，通过灭活命令将电子标签灭活(非物理损坏)，电子标签将不再响应阅读器的任何命令，电子标签无效。电子标签灭活的实现方法是将电子标签内部非挥发性存储器灭活标志位置位，电子标签上电时读取该非挥发性存储器的值，如果被置位，电子标签立即进入灭活状态。In the field of radio frequency identification, UHF passive electronic tags (hereinafter referred to as electronic tags) receive electromagnetic field energy through antennas and supply power to chips. At the end of the electronic tag's life cycle, the electronic tag will be inactivated (non-physical damage) through the inactivation command, and the electronic tag will no longer respond to any commands from the reader, and the electronic tag will be invalid. The implementation method of electronic tag inactivation is to set the non-volatile memory inactivation flag inside the electronic tag, and read the value of the non-volatile memory when the electronic tag is powered on. If it is set, the electronic tag immediately enters the inactivation state.
由于电子标签低功耗的要求，非挥发性存储器并不能及时将电子标签中的数据擦除，在电子标签灭活后，电子标签中的数据还存在于非挥发性存储器中，存在安全隐患。Due to the low power consumption requirements of the electronic tag, the non-volatile memory cannot erase the data in the electronic tag in time. After the electronic tag is deactivated, the data in the electronic tag still exists in the non-volatile memory, which poses a security risk.

具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚明白，下面结合附图对本发明实施例做进一步详细说明。在此，本发明的示意性实施例及其说明用于解释本发明，但并不作为对本发明的限定。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
如图1所示，本发明实施例中，超高频无源电子标签灭活方法的处理流程可以包括：As shown in Figure 1, in the embodiment of the present invention, the processing flow of the UHF passive electronic tag inactivation method may include:
步骤101、超高频无源电子标签(下称电子标签)在生命周期结束时接收阅读器发送的灭活命令，向所述阅读器返回接收响应，其中，所述灭活命令携带通知擦除数据的指示参数，所述接收响应携带时间参数；
步骤102、所述阅读器在接收到所述接收响应后，根据所述接收响应中的时间参数向所述电子标签发送相应时长的连续载波；
步骤103、所述电子标签接收所述连续载波，根据所述指示参数擦除数据；
步骤104、所述电子标签根据所述灭活命令进行灭活处理。
由图1所示流程可以得知，本发明实施例中，超高频无源电子标签在生命周期结束时接收阅读器发送的灭活命令，所述灭活命令携带通知擦除数据的指示参数；所述电子标签根据所述指示参数擦除数据；所述电子标签根据所述灭活命令进行灭活处理；能够使电子标签灭活后，电子标签中的数据因已被擦除而并不存在于非挥发性存储器中，从而杜绝安全隐患，大幅度地提升电子标签的安全性能。所述电子标签在接收到所述灭活命令后，向所述阅读器返回接收响应，所述接收响应携带时间参数；所述阅读器在接收到所述接收响应后，根据所述接收响应中的时间参数向所述电子标签发送相应时长的连续载波；所述电子标签接收所述连续载波，并进行数据擦除；这样，通过阅读器与电子标签协商连续载波的发送时长，可以保证电子标签将内部的所有数据全部擦除，进一步提升电子标签的安全性能。It can be known from the process shown in Figure 1 that in the embodiment of the present invention, the UHF passive electronic tag receives the deactivation command sent by the reader at the end of the life cycle, and the deactivation command carries an indication parameter notifying the erasure of data ; The electronic tag erases data according to the indicated parameters; The electronic tag performs inactivation processing according to the inactivation command; After the electronic tag can be inactivated, the data in the electronic tag is not erased because it has been erased. It exists in the non-volatile memory, thereby eliminating potential safety hazards and greatly improving the safety performance of electronic tags. After the electronic tag receives the inactivation command, it returns a reception response to the reader, and the reception response carries a time parameter; after the reader receives the reception response, it The time parameter sends the corresponding continuous carrier wave to the electronic tag; the electronic tag receives the continuous carrier wave and performs data erasure; in this way, the reader and the electronic tag negotiate the sending time of the continuous carrier wave, which can ensure the All internal data will be erased to further improve the security performance of electronic tags.
由于电子标签是无源器件，因此在根据灭活命令中的指示参数进行数据擦除时，可以由阅读器向其发送连续载波以提供能量。电子标签在接收到灭活命令后，向阅读器返回接收响应，在该接收响应中携带时间参数，以告知阅读器需要发送多长时间的连续载波，这一段时间需要能够保证电子标签将内部的所有数据全部擦除，而不会出现数据未擦除完的情况。Since the electronic tag is a passive device, the reader can send continuous carrier waves to it to provide energy when erasing data according to the indicated parameters in the inactivation command. After receiving the inactivation command, the electronic tag returns a receiving response to the reader, and the receiving response carries a time parameter to inform the reader how long the continuous carrier wave needs to be sent. This period of time needs to be able to ensure that the internal All data is completely erased, and there will be no situation where the data is not completely erased.
一个实施例中，所述电子标签向所述阅读器返回所述接收响应，可以包括：In one embodiment, the electronic tag returns the receiving response to the reader, which may include:
所述电子标签将所述接收响应中的时间参数设置为所述连续载波的发送时长相应的取值。The electronic tag sets the time parameter in the receiving response to a value corresponding to the sending duration of the continuous carrier wave.
具体实施时，时间参数的取值应对应于阅读器发送连续载波的时长。例如，所述电子标签将所述接收响应中的时间参数设置为T＝0x00～0xFE；阅读器发送连续载波的时长为T×20ms。又如，该时间参数也可以就是阅读器发送连续载波的时长。During specific implementation, the value of the time parameter should correspond to the duration for the reader to send continuous carrier waves. For example, the electronic tag sets the time parameter in the receiving response as T=0x00˜0xFE; the duration for the reader to send continuous carrier waves is T×20ms. For another example, the time parameter may also be the duration for the reader to send continuous carrier waves.
一个实施例中，所述接收响应可以包括标志位、随机数RN(Random Number)、所述时间参数和循环冗余校验码CRC-16。具体实施时，接收响应的具体组成部分也可以根据实际需要进行设置，此处的组成形式仅为一例。In an embodiment, the receiving response may include a flag bit, a random number RN (Random Number), the time parameter and a cyclic redundancy check code CRC-16. During specific implementation, the specific components of the received response may also be set according to actual needs, and the composition form here is only an example.
下表提供了电子标签向阅读器返回的接收响应的一个具体示例：The following table provides a specific example of the receipt response returned by the transponder to the reader:
一个实施例中，阅读器在发送连续载波时，还可以将接收的时间参数与延时结合考虑，这里的延时是指从阅读器发送灭活命令，至电子标签向阅读器返回灭活处理成功响应的时长。例如，所述阅读器根据所述接收响应中的时间参数向所述电子标签发送相应时长的连续载波，可以包括：In one embodiment, when the reader sends continuous carrier waves, it can also consider the received time parameter and the delay. The delay here refers to sending the deactivation command from the reader until the electronic tag returns the deactivation process to the reader. The duration of a successful response. For example, the reader sends a continuous carrier wave of corresponding duration to the electronic tag according to the time parameter in the received response, which may include:
所述阅读器发送Min(TREPLY，T×20ms)时长的连续载波；其中，TREPLY为从所述阅读器发送所述灭活命令，至所述电子标签向所述阅读器返回灭活处理成功响应的时长；T为所述接收响应中时间参数的取值。The reader sends a continuous carrier wave with a duration of Min(TREPLY , T×20ms); wherein, TREPLY is the inactivation command sent from the reader until the electronic tag returns the inactivation process to the reader The duration of the successful response; T is the value of the time parameter in the received response.
图2为电子标签灭活处理的一个示例图。由图2可见，要灭活电子标签，阅读器应发送灭活命令(本例中也可称为Kill命令)，若电子标签监测到接收的灭活命令无效时，会忽略该灭活命令；此时电子标签无响应，并保持当前状态。若电子标签监测到接收的灭活命令有效时，可以分如下几种情况进行处理：Fig. 2 is an example diagram of electronic tag inactivation processing. It can be seen from Figure 2 that to inactivate the electronic tag, the reader should send an inactivation command (in this example, it can also be called a Kill command), and if the electronic tag detects that the received inactivation command is invalid, the inactivation command will be ignored; At this time, the electronic tag does not respond and maintains the current state. If the electronic tag detects that the inactivation command received is valid, it can be processed in the following situations:
若灭活命令中携带通知擦除数据的指示参数，则返回携带时间参数的接收响应，如上表所示，该接收响应包含标志位(1位数据0)、RN(电子标签的handle)、时间参数T及从标志位至T结束位计算得到的CRC-16；电子标签接收阅读器根据该时间参数发送的相应时长的连续载波，擦除数据并进行灭活处理，灭活成功时可返回灭活成功响应；若电子标签在灭活处理中遭遇错误，则电子标签可以向阅读器发送错误码，并保持当前状态；If the inactivation command carries an indication parameter for notifying erasing data, a receiving response carrying a time parameter is returned. As shown in the above table, the receiving response includes a flag bit (1 bit data 0), RN (handle of the electronic tag), time The parameter T and the CRC-16 calculated from the flag bit to the end bit of T; the electronic tag receives the continuous carrier wave of the corresponding duration sent by the reader according to the time parameter, erases the data and performs inactivation processing, and returns off when the inactivation is successful If the electronic tag encounters an error in the inactivation process, the electronic tag can send an error code to the reader and maintain the current state;
若灭活命令中未携带通知擦除数据的指示参数，则进行灭活处理，灭活成功时可返回灭活成功响应，并不进行数据擦除。If the deactivation command does not carry an indication parameter for notifying erasure of data, deactivation processing is performed, and a deactivation success response may be returned when the deactivation is successful, and data erasure is not performed.
由此可见，根据电子标签灭活处理成功与否，阅读器可获得多种可能结果：It can be seen that, depending on whether the electronic tag inactivation process is successful or not, the reader can obtain multiple possible results:
灭活成功：完成灭活后，电子标签应立即将自身置为灭活状态，且以后不再对阅读器进行响应；Successful inactivation: After the inactivation is completed, the electronic tag should immediately put itself in the inactivation state, and will not respond to the reader in the future;
电子标签遇到错误：当电子标签在灭活处理中遭遇错误，则电子标签可以向阅读器发送错误码；The electronic tag encounters an error: when the electronic tag encounters an error in the inactivation process, the electronic tag can send an error code to the reader;
灭活未成功：电子标签可以在灭活成功后向阅读器返回响应，如果阅读器未能在约定的时间内收到响应，则可以确定灭活没有成功完成。阅读器可发出Req_RN(随机数获取)命令(包含该电子标签的handle)验证该电子标签是否仍处于该阅读器的射频电磁场内，并可再次启动灭活处理。Unsuccessful inactivation: The electronic tag can return a response to the reader after the inactivation is successful. If the reader fails to receive the response within the agreed time, it can be determined that the inactivation was not completed successfully. The reader can issue a Req_RN (random number acquisition) command (including the handle of the electronic tag) to verify whether the electronic tag is still in the radio frequency electromagnetic field of the reader, and can start the inactivation process again.
一个实施例中，所述电子标签根据所述灭活命令进行灭活处理之后，还可以包括：In one embodiment, after the electronic tag is inactivated according to the inactivation command, it may further include:
所述电子标签向所述阅读器返回灭活响应，所述灭活响应携带时间参数；The electronic tag returns a deactivation response to the reader, and the deactivation response carries a time parameter;
所述阅读器根据所述灭活响应中的时间参数确定所述电子标签是否已擦除全部数据并成功灭活。The reader determines whether the electronic tag has erased all data and successfully deactivated according to the time parameter in the inactivation response.
这样，电子标签通过向阅读器返回上述灭活响应，阅读器可以根据灭活响应中的时间参数确定电子标签是否已擦除全部数据并成功灭活，这样可以确保电子标签在灭活时已没有剩余数据存在于非挥发性存储器中，提升标签安全性能；在阅读器确定电子标签是否已擦除全部数据并成功灭活后，阅读器不再发送连续载波。In this way, by returning the above inactivation response to the reader, the reader can determine whether the electronic tag has erased all data and successfully inactivated according to the time parameter in the inactivation response, which can ensure that the electronic tag has no The remaining data exists in the non-volatile memory, which improves the security performance of the tag; after the reader determines whether the electronic tag has erased all the data and successfully inactivated, the reader no longer sends continuous carrier waves.
具体实施时，所述电子标签向所述阅读器返回所述灭活响应，可以包括：所述电子标签将所述灭活响应中的时间参数设置为指定值，所述指定值用于指示所述电子标签是否已擦除全部数据并成功灭活。During specific implementation, the electronic tag returning the inactivation response to the reader may include: the electronic tag setting the time parameter in the inactivation response to a specified value, and the specified value is used to indicate the Whether all the data of the above-mentioned electronic tags have been erased and successfully inactivated.
例如，所述电子标签将所述灭活响应中的时间参数设置为0xFF，以指示所述电子标签已擦除全部数据并成功灭活；这样，在阅读器接收到灭活响应后，若确定灭活响应中的时间参数设置为0xFF，则阅读器可以确定电子标签已擦除全部数据并成功灭活。For example, the electronic tag sets the time parameter in the inactivation response to 0xFF to indicate that the electronic tag has erased all data and successfully inactivated; in this way, after the reader receives the inactivation response, if it is determined If the time parameter in the inactivation response is set to 0xFF, the reader can determine that the electronic tag has erased all data and successfully inactivated.
具体实施时，灭活响应中除包括上述时间参数外，还可以包括标志位、随机数RN和循环冗余校验码CRC-16等信息。下表提供了电子标签向阅读器返回的灭活响应的一个具体示例：During specific implementation, in addition to the above time parameters, the inactivation response may also include information such as a flag bit, a random number RN, and a cyclic redundancy check code CRC-16. The following table provides a specific example of a kill response that a transponder returns to a reader:
