无线体域网需要一种安全、高效的密钥协商方法，特别是对于传感器/控制器间的通信。通信双方在物理层共享相似的信道信息，而对方无法掌握。基于物理层信息的密钥生成和协商仅将校验符号从通信信道的一侧传递到另一侧。然后接收端可以根据接收到的校验符号和类似的本地信息恢复发送端存储的原始信息。这种方式既可以达到较高的安全性，又可以达到较高的效率。本文进一步提高了上述方法的安全性和效率。
A secure and efficient key agreement method is required by Wireless Body Area Network, especially for intersensor/controller communication. The communicating parties share similar channel information at physical layer that the others cannot grasp. The physical layer information-based key generation and agreement will only pass check symbols from one side to the other side of the communication channel. Then the receiving side can recover the original information stored at the sending side from the received check symbols and the similar local information. This way can achieve both high security and efficiency. This paper further improves the security and efficiency of the above method.
