Three-party password handshake protocol

The document describes a three-party cryptographic handshake protocol in a wireless network, wherein an observer receives a packet from a beacon comprising an exponentiation of a random value and a proxy value, and generates an end-to-end encrypted transient identifier (E2EE-EID) from the exponentiation of the random value and the proxy value. The observer generates a message for the owner, selects a private key, and computes an exchanged key by using the private key and the E2EE-EID. The observer extracts a common symmetric key from the exchanged keys, encrypts the message by using the common symmetric key, and transmits the encrypted message to the owner. 本文档描述一种无线网络中的三方密码握手协议，其中观测器从信标接收包括随机值的乘幂和代理值的分组，并且从随机值的乘幂和代理值生成端到端加密的短暂标识符(E2EE-EID)。观测器生成针对所有者的消息，选择私钥，并且使用私钥和E2EE-EID来计算交换的密钥。观测器从交换的密钥中提取公共对称密钥，使用公共对称密钥来对消息进行加密，并且将经加密的消息传送到所有者。
