在一些实施例中，可以具有多种感知类型(Sensing Type)。例如，基于信道状态信息(Channel State Information，CSI)的感知类型，即CSI-based Sensing，该感知类型是通过处理接收到的感知测量信号的CSI获得sensing测量结果。又例如，基于反射信号的感知类型，即Radar-based Sensing，该感知类型是通过处理接收到的感知测量信号的反射信号获得sensing测量结果。In some embodiments, there may be multiple sensing types (Sensing Type).

This sensing type obtains the sensing measurement result by processing the reflection signal of the received sensing measurement signal.
在一些实施例中，建立感知会话时，站点设备间可能需要一一协商感知角色和操作参数，或者站点设备声明自身的角色和操作参数。In some embodiments, when establishing a sensing session, the site devices may need to negotiate sensing roles and operating parameters one by one, or the site devices declare their own roles and operating parameters.
在一些实施例中，感知会话发起设备可以通过测量设置(Measurement Setup)流程来设置多组测量参数，一组测量参数(用Measurment Setup ID来标识，可以等价于突发组(Burst Group))可以应用于多次测量，一次测量认为是一个测量实例(用Measurement Instance ID来标识，可以等价于Burst)。In some embodiments, the sensing session initiating device can set multiple sets of measurement parameters through a measurement setup (Measurment Setup) process, and a set of measurement parameters (identified by a Measurement Setup ID, which can be equivalent to a burst group (Burst Group)) It can be applied to multiple measurements, and one measurement is considered as a measurement instance (identified by Measurement Instance ID, which can be equivalent to Burst).
在一些场景中，若只有一对设备进行感知测量，可以采用非基于触发(non-Trigger Based，non-TB)的测量。具体地，若感知发起设备是感知信号发送设备，则感知信号发送设备可以发送空数据物理层协议数据单元宣告(Null Data Physical Protocol Data Unit Announcement，NDPA)帧来宣告测量开始，在短帧间间隔(short interframe space，SIFS)时间后发送空数据物理层协议数据单元(Null Data Physical Protocol Data Unit，NDP)帧，感知信号接收设备接收该NDP帧产生测量数据，在SIFS时间后感知信号接收设备给感知发起设备上报测量数据。In some scenarios, if only one pair of devices performs perception measurements, non-Trigger Based (non-TB) measurements can be used. Specifically, if the sensing initiating device is a sensing signal sending device, the sensing signal sending device may send a Null Data Physical Protocol Data Unit Announcement (NDPA) frame to announce the start of the measurement, and the short inter-frame interval After (short interframe space, SIFS) time, send a null data physical layer protocol data unit (Null Data Physical Protocol Data Unit, NDP) frame, and the sensing signal receiving device receives the NDP frame to generate measurement data, and after the SIFS time, the sensing signal receiving device sends The perception initiating device reports measurement data.
在一些场景中，有多个设备参与感知测量，为提高效率，可以采用基于触发(Trigger Based，TB)的测量。例如，在轮询(Polling)阶段，接入点设备发送轮询触发帧来探测感知参与设备是否可用。在上行感知测量(UL sensing sounding)阶段，接入点设备发送触发帧(或称，测量触发帧)，以及接收感知信号发送设备发送的NDP帧，其中，该触发帧用于触发感知信号发送设备发送NDP帧。在下行测量(DL sensing sounding)，接入点设备发送NDPA帧和NDP帧。进一步地，在上报阶段，在感知发送设备发送NDP帧后，接入点设备发送反馈触发帧，感知信号接收设备接收该反馈触发帧后给感知发起设备上报测量数据。In some scenarios, there are multiple devices participating in the perception measurement. To improve efficiency, trigger-based (Trigger Based, TB) measurement can be used. For example, in a polling (Polling) phase, the access point device sends a polling trigger frame to detect whether the sensing participant device is available. In the uplink sensing measurement (UL sensing sounding) stage, the access point device sends a trigger frame (or measurement trigger frame), and receives the NDP frame sent by the sensing signal sending device, wherein the trigger frame is used to trigger the sensing signal sending device Send NDP frames. In the downlink measurement (DL sensing sounding), the access point device sends NDPA frames and NDP frames. Further, in the reporting phase, after the sensing sending device sends the NDP frame, the access point device sends a feedback trigger frame, and the sensing signal receiving device reports measurement data to the sensing initiating device after receiving the feedback trigger frame.
在感知测量中，感知信号接收设备可以基于感知发起设备的显式请求进行测量结果的上报，例如该显式请求可以是感知反馈请求帧或者感知上报触发帧，或者，基于隐式请求进行测量结果的上报，例如由NDP触发上报。In perception measurement, the perception signal receiving device can report the measurement result based on the explicit request of the perception initiating device, for example, the explicit request can be a sensory feedback request frame or a sensory report trigger frame, or the measurement result can be reported based on an implicit request report, for example, the report is triggered by NDP.
在一些有较高安全和隐私要求的感知场景中，例如感知靠近的人物是否存活，例如从多个人中感知识别某个人的身份/存在性，又例如感知人的跌倒/手势，又例如感知人的活动轨迹，再例如人的生命体征(例如呼吸/心跳)感知，需要防止恶意设备通过仿冒参与测量的设备来干扰测量，以及防止恶意设备频繁触发参与测量的设备进行测量，即拒绝服务攻击(Deny of Service，DOS)等。In some sensing scenarios with high security and privacy requirements, such as sensing whether close people are alive, such as sensing and identifying a person’s identity/existence from multiple people, and sensing people’s falls/gestures, and sensing people’s activity track, such as the perception of human vital signs (such as breathing/heartbeat), it is necessary to prevent malicious devices from interfering with the measurement by impersonating the device participating in the measurement, and to prevent the malicious device from frequently triggering the measurement of the device participating in the measurement, that is, a denial of service attack ( Deny of Service, DOS) and so on.
因此，如何进行安全的感知是一项亟需解决的问题。Therefore, how to perform security perception is an urgent problem to be solved.

That is, the perception initiating device can use the ISTA-LTF-KEY to generate a protected LTF.

That is, the sensing response device can generate a protected LTF by using the RSTA-LTF-KEY.
在一些实施例中，所述CTR可以用于生成SAC，该SAC可以用于验证测量中所使用的CTR，和/或，用于验证上报的测量结果是否由已发送感知信号产生，其中，该已发送感知信号包括受保护的LTF，该受保护的LTF由CTR生成的ISTA-LTF-KEY或RSTA-LTF-KEY所生成。In some embodiments, the CTR can be used to generate a SAC, and the SAC can be used to verify the CTR used in the measurement, and/or, to verify whether the reported measurement result is generated by the sent sensing signal, wherein the The sent sensing signal includes a protected LTF generated by the ISTA-LTF-KEY or RSTA-LTF-KEY generated by the CTR.

实施例一：Embodiment one:
在该实施例一中，在感知会话建立阶段，所述第一设备向所述第二设备发送初始secure LTF参数。In the first embodiment, during the perception session establishment phase, the first device sends an initial secure LTF parameter to the second device.
应理解，第一设备可以通过感知会话建立阶段向第二设备发送的任意帧携带初始secure LTF参数。It should be understood that the first device may carry the initial secure LTF parameter in any frame sent to the second device through the perception session establishment phase.
作为示例，所述初始secure LTF参数是通过第一请求帧发送的，其中，所述第一请求帧用于请求建立目标感知会话。As an example, the initial secure LTF parameter is sent through a first request frame, where the first request frame is used to request establishment of a target awareness session.
在一些实施例中，所述第一请求帧又称感知会话建立请求帧(SENS Setup Request frame)，或者会话建立请求帧。In some embodiments, the first request frame is also called a sensory session setup request frame (SENS Setup Request frame), or a session setup request frame.

例如，在交互安全感知能力时，仅指示了是否支持安全的感知，未指示支持的感知会话类型，则在感知会话建立阶段可以仅指示待建立的感知会话是否为安全的感知会话。For example, when exchanging security awareness capabilities, it only indicates whether to support security awareness, but does not indicate the supported awareness session type, then in the awareness session establishment phase, it may only indicate whether the awareness session to be established is a secure awareness session.
可选地，若第一请求帧指示待建立的感知会话为安全的感知会话，表示待建立的感知会话为仅安 全类型的感知会话，或混合类型的感知会话。Optionally, if the first request frame indicates that the sensing session to be established is a secure sensing session, it means that the sensing session to be established is a sensing session of only a security type, or a sensing session of a mixed type.

在一些实施例中，可以通过第一请求帧中是否携带secure LTF参数确定待建立的感知会话类型。In some embodiments, the type of the perception session to be established can be determined by whether the secure LTF parameter is carried in the first request frame.
例如，若第一请求帧中不携带secure LTF参数，则表示建立非安全类型的感知会话。For example, if the secure LTF parameter is not carried in the first request frame, it means that a non-secure perception session is established.
又例如，若第一请求帧中携带secure LTF参数，则表示建立仅安全类型的感知会话，或者，混合类型的安装会话。For another example, if the secure LTF parameter is carried in the first request frame, it indicates that only a security-type awareness session is established, or a mixed-type installation session is established.

在一些实施例中，第一请求帧中携带的初始secure LTF参数可以适用于该目标感知会话中的所有测量实例。In some embodiments, the initial secure LTF parameter carried in the first request frame may apply to all measurement instances in the target awareness session.
在另一些实施例中，可以通过额外的指示信息指示第一请求帧中携带的初始secure LTF参数是否适用于该目标感知会话的每个测量设置。In other embodiments, additional indication information may be used to indicate whether the initial secure LTF parameter carried in the first request frame is applicable to each measurement setting of the target awareness session.
可选地，在未指示某个测量设置不使用该初始secure LTF参数时，默认该测量设置使用该初始secure LTF参数。Optionally, when a measurement setting is not instructed not to use the initial secure LTF parameter, the measurement setting uses the initial secure LTF parameter by default.
在一些实施例中，在测量设置(measurement setup)建立阶段，所述第一设备向所述第二设备发送第一指示信息，所述第一指示信息用于指示是否启用安全的感知，或者，所述第一指示信息用于指示待建立的测量设置是否使用该初始secure LTF参数。In some embodiments, during the establishment of a measurement setup (measurement setup), the first device sends first indication information to the second device, where the first indication information is used to indicate whether security awareness is enabled, or, The first indication information is used to indicate whether the measurement setting to be established uses the initial secure LTF parameter.
例如，对于混合类型的感知会话，第一设备可以通过第一指示信息指示感知会话中的部分测量设置中的测量实例启用安全的感知，即使用初始secure LTF参数。For example, for a mixed-type sensing session, the first device may use the first indication information to indicate that the measurement instances in some measurement settings in the sensing session enable secure sensing, that is, use the initial secure LTF parameter.
可选地，对于混合类型的感知会话，在测量设置(measurement setup)建立阶段，所述第一设备未向所述第二设备发送第一指示信息时，默认表示待建立的测量设置启用安全的感知，或者，默认表示待建立的测量设置不启用安全的感知。Optionally, for a mixed-type sensing session, when the first device does not send the first indication information to the second device during the measurement setup establishment phase, it defaults to indicate that the measurement setup to be established is enabled with security Awareness, or default means that the measurement settings to be established do not enable security awareness.
应理解，在本申请实施例中，是否启用安全的感知也可以替换为是否启用安全的测量，或者，是否启用安全的感知测量，上述表述是等价的，可以相互替换。It should be understood that, in this embodiment of the present application, whether to enable security awareness may also be replaced with whether to enable security measurement, or whether to enable security awareness measurement, the above expressions are equivalent and may be replaced with each other.
在一些实施例中，所述第一指示信息通过第二请求帧发送，所述第二请求帧用于请求建立测量设置。In some embodiments, the first indication information is sent through a second request frame, and the second request frame is used to request establishment of measurement settings.

可选地，在启用安全的感知的情况下，对于该测量设置标识对应测量设置中的测量实例，感知参与设备可以使用CTR值生成LTF密钥，进一步使用该LTF密钥生成受保护的LTF，在感知信号中携带该受保护的LTF。Optionally, when secure sensing is enabled, for the measurement instance in the measurement setting corresponding to the measurement setting identifier, the sensing participating device may use the CTR value to generate an LTF key, and further use the LTF key to generate a protected LTF, This protected LTF is carried in the sensing signal.
例如，感知发起设备可以根据该CTR的初始值生成ISTA-LTF-KEY，进一步使用ISTA-LTF-KEY来保护其发送的PPDU(例如NDP帧)中的LTF。For example, the sensing initiating device can generate an ISTA-LTF-KEY according to the initial value of the CTR, and further use the ISTA-LTF-KEY to protect the LTF in the PPDU (such as an NDP frame) it sends.
又例如，感知响应设备可以根据该CTR的初始值生成RSTA-LTF-KEY，进一步使用RSTA-LTF-KEY来保护其发送的PPDU(例如NDP帧)中的LTF。For another example, the sensing response device may generate an RSTA-LTF-KEY according to the initial value of the CTR, and further use the RSTA-LTF-KEY to protect the LTF in the PPDU (such as an NDP frame) it sends.

如图5所示，可以包括如下步骤：As shown in Figure 5, the following steps may be included:
S2001，第一设备向第二设备发送感知会话建立请求帧。S2001. The first device sends a perception session establishment request frame to the second device.
其中，该感知会话建立请求包括感知会话发起设备标识和第三指示信息，用于指示待建立的感知会话类型，例如仅安全类型，或者，混合类型。Wherein, the perception session establishment request includes the perception session initiating device identifier and third indication information, which is used to indicate the type of the perception session to be established, for example, the security type only, or the hybrid type.

其中，该测量设置建立请求帧可以包括感知会话发起设备标识、测量设置标识和初始secure LTF参数。Wherein, the measurement setting establishment request frame may include a perception session initiating device identifier, a measurement setting identifier and an initial secure LTF parameter.
在该实施例中，待建立的测量设置为安全的测量设置。In this embodiment, the measurement settings to be established are secure measurement settings.
以下，对初始安全长训练字段参数在测量中的使用进行说明。为便于区分和说明，将CTR的初 始值记为CTR1，将SAC1的初始值记为SAC1。Hereinafter, the use of the initial safety long training field parameter in measurement will be described. For the convenience of distinction and description, the initial value of CTR is recorded as CTR1, and the initial value of SAC1 is recorded as SAC1.
对于non-TB的测量实例，在安全的测量设置的测量实例中，感知发起设备或代理设备可以通过第一宣告帧携带SAC1，指示本次测量将要使用的SAC，其中，所述第一宣告帧用于宣告该感知发起设备或其代理设备将要发送感知信号(例如NDP帧)。For non-TB measurement instances, in the measurement instance of secure measurement settings, the perception initiator device or proxy device may carry SAC1 through the first announcement frame, indicating the SAC to be used for this measurement, wherein the first announcement frame It is used to announce that the sensing initiating device or its proxy device will send a sensing signal (such as an NDP frame).
进一步地，感知发起设备或代理设备发送感知信号，例如NDP帧，该NDP帧中携带受保护的LTF，该受保护的LTF由LTF密钥(例如，ISTA-LTF-KEY或RSTA-LTF-KEY)生成，该LTF密钥根据SAC1对应的CTR(即CTR1)生成。Further, the sensing initiating device or the proxy device sends a sensing signal, such as an NDP frame, which carries a protected LTF, and the protected LTF is determined by the LTF key (for example, ISTA-LTF-KEY or RSTA-LTF-KEY ), the LTF key is generated according to the CTR corresponding to SAC1 (namely CTR1).
对应地，感知信号接收设备接收该感知信号(例如NDP帧)，使用第一宣告帧中的SAC1对应的CTR1所生成的LTF密钥(例如，ISTA-LTF-KEY或RSTA-LTF-KEY)解析该感知信号中的受保护的LTF。Correspondingly, the sensing signal receiving device receives the sensing signal (such as an NDP frame), and uses the LTF key (such as ISTA-LTF-KEY or RSTA-LTF-KEY) generated by CTR1 corresponding to SAC1 in the first announcement frame to parse Protected LTF in this perception signal.
应理解，感知信号接收设备接收第一宣告帧后，可以获知SAC1，由于SAC由对应的CTR值唯一生成，则感知信号接收设备可以确定SAC1对应的CTR值和该感知信号接收设备缓存的CTR值是否一致。例如，可以利用自身所缓存的CTR值计算出SAC值，通过比较该SAC值和SAC1是否一致确定该SAC1对应的CTR值和缓存的CTR值是否一致，若SAC1与计算出的SAC值一致，则说明使用的CTR值和缓存的CTR值一致，否则说明不一致。可选地，在不一致的情况下，该感知信号接收设备可以不执行测量，有利于避免恶意设备频繁触发设备进行测量，即拒绝服务攻击(Deny of Service，DOS)。It should be understood that after receiving the first announcement frame, the sensing signal receiving device can know SAC1. Since SAC is uniquely generated by the corresponding CTR value, the sensing signal receiving device can determine the CTR value corresponding to SAC1 and the CTR value cached by the sensing signal receiving device Is it consistent.

其中，初始安全长训练字段参数的获取方式可以参考方法200中的详细描述，为了简洁，这里不再赘述。Wherein, the method for obtaining the parameters of the initial security long training field can refer to the detailed description in the method 200, and for the sake of brevity, details are not repeated here.

也就是说，对于获取CTR的初始值后的第一个测量实例，可以根据该CTR进行测量，在之后的每个测量实例中，CTR值都增加预定义值，或者增加随机正整数N。That is to say, for the first measurement instance after the initial value of CTR is obtained, measurement can be performed according to the CTR, and in each subsequent measurement instance, the CTR value is increased by a predefined value, or increased by a random positive integer N.
因此，基于上述计数方式，CTR的值在每次测量后均会发生变化，下次测量所使用的CTR值跟上一次测量所使用的CTR值不同，因此，每次测量中所保护的LTF都会变化，有利于防止重放攻击(Replay Attack)。Therefore, based on the above counting method, the value of CTR will change after each measurement, and the CTR value used in the next measurement is different from the CTR value used in the previous measurement. Therefore, the LTF protected in each measurement will be Changes are helpful to prevent Replay Attacks.
