密钥协商是安全通信的重要环节，通过密钥协商协议可在通信节点之间建立共享会话密钥，以便实现网络中的安全通信。在物联网环境下，文章提出的密钥协商协议是在基于身份的可认证密钥协商基础上的无双线性对的可认证密钥协商协议。该协议主要包括3个部分：初始化、参数提取和密钥协商。与利用双线性对的密钥协商协议相比，该协议不仅提供了相同层次的安全性与可扩展性，且在能量开销、时间开销和计算复杂度方面具有明显的优势。

The key agreement is an important part of the secure communication. By the key agreement protocol. the shared session key is established between communication nodes in order to achieve secure communications in network. In the context of the Internet of Things, the authenticated key agreement protocol proposed in this paper is based on identity-based authenticated key agreement protocol without the bilinear pairing. The protocol mainly includes three parts: initialization, parameter extraction and key agreement. Comparing with the key agreement protocol using bilinear pairings, the protocol not only provides the same level of security and scalability, but also has obvious advantages in terms of energy overhead, time overhead and computational complexity.
