“随机否”攻击者和“随机错误”攻击者和上述情况一致，不再说明。我们将得

The "random no" attacker and the "random error" attacker are the same as the above situation, and will not be explained again. We will get different weights for each Internet of Things device, and add these weights together, and the result is positive means that the PU exists, and negative means that the PU does not exist. The final decision f can be expressed as follows.

"Random no" attackers and "random error" attackers are consistent with the above situation and will not be explained any more.

If the result is positive, it means that Pu exists, and if it is negative, it means that Pu does not exist. The final decision f can be expressed as follows.<br>
