5)AF或基站或UE将感知隐私需求直接发送给SensingMF(不需要经过AMF转发)。
步骤2：第二设备获取第一信息后，确定以下信息的至少之一：

步骤3：第二设备生成当前时刻的第一感知信号r(m)，m＝0,1,2,M-1对应频域采样点或子载波序号。
例如第一感知信号采用基于正交相移键控(Quadrature Phase Shift Keying，QPSK)调制的伪随机序列(伪随机(Pseudo Noise，PN)序列，同当前5G NR标准)，即生成公式为：
其中，c(n)为PN序列，构造方式为：
c(n)＝(x1(n+NC)+x2(n+NC))mod2
x1(n+31)＝(x1(n+3)+x1(n))mod2
x2(n+31)＝(x2(n+3)+x2(n+2)+x2(n+1)+x2(n))mod2
其中，NC＝1600，并且第一个m序列x1(n)初始化方式为x1(0)＝1,x1(n)＝0,n＝1,2,...,30，第二个m序列x2(n)初始化方式为cinit表示初始化因子，与PN序列的具体用途相关联。
不同时刻对应的第一感知信号示例图3所示，假设当前时刻为t1，对应的第一感知信号r(m)在频域上占据m个子载波。

c1init＝(210(2nsensingID+1)+nsensingID)mod231
每个时刻对应的第一加密信号使用相同的c1init，生成的第一加密信号特征为：每个时刻对应的第一加密信号相同，每个加密信号中的元素不完全相同(与PN序列特性相关)。
步骤5：第二设备根据当前发送时刻对应的第一感知信号和第一加密信号生成目标感知信号，具体的，方式为r‘(m)＝r(m)*r1(m)，m＝0,1,2…,M-1对应频域采样点或子载波序号。
具体的，如图3所示，t1时刻、t2时刻、t3时刻…对应的第一感知信号和第一加密信号分别进行频域相乘。
步骤6：第二设备向第三设备发送目标感知信号，第三设备接收到目标感知信号后根据已知的第一感知信号r(m)进行信道估计得到的第一信道信息H′(该信道信息为非真实信道信息)，此时第三设备根据H′进行时延和多普勒的检测结果如下，此时能够检测出确定的多普勒/速度信息，无法获得确定的时延/距离信息。

步骤2：第二设备生成第一感知信号，生成方式同实施例一。
步骤3：第二设备生成第一加密信号r1(m)，m＝0,1,2…,M-1对应频域采样点或子载波序号。
例如第一感知信号采用基于QPSK调制的伪随机序列，生成方式同第一感知信号，可以是例如：
其中PN序列生成初始化因子与感知业务ID或感知加密ID关联，与时间信息无关，例如可以是：
其中，表示每帧中的时隙个数，表示每个时隙中的符号个数，nf表示当前帧号，表示当前时隙号，l表示当前符号序号。如此一来，每个时刻对应的第一加密信号使用不同的c1init，生成的第一加密信号特征为：每个时刻对应的第一加密信号不完全相同，每个加密信号中的元素相同(即不同频域采样点对应的r1(m)相同)。
步骤4：第二设备根据当前发送时刻对应的第一感知信号和第一加密信号生成目标感知信号，具体的，方式为r‘(m)＝r(m)*r1(m)，m＝0,1,2…,M-1对应频域采样点或子载波序号。

需要说明的是，本申请将第二设备发送信号称作是目标感知信号，将第三设备接收的信号(通过了信道)也称作是目标感知信号，这样描述的目的是为了便于对应，方便理解，实际上，上述两者的具体内容可能不同，例如，第二设备发送信号对于第三设备而言可以是本地参考信号，用来对接收的参 考序列进行相关计算得到信道估计结果；而第三设备接收的信号可以是接收信号。
可选地，作为一个实施例，所述方法还包括：所述第三设备根据所述目标感知信号生成第一感知测量结果；所述第三设备发送所述第一感知测量结果。例如，第三设备可以将第一感知测量结果发送给第二设备；第三设备还可以直接将第一感知测量结果发送给第一设备；第三设备还可以将第一感知测量结果发送给第四设备。

由于第二设备未知第三感知信号，因此，即使第二设备获取到了第二感 知测量结果，也无法获取正确的感知测量结果，相当于是接收设备(即第三设备)也对感知信号进行了加密处理，有利于提升感知结果的安全性。
该实施例中，感知信号的接收设备也可以根据感知加密需求对感知信号进行加密处理，使得仅特定设备能够获取正确的感知测量结果，有利于提升感知结果的安全性。
