摘　　要：在气象信息技术快速发展的当下,气象信息安全成为研究要点。密钥协商协议能够产生一个共同会话密钥,从而保证群组内气象信息加解密的安全性,群组成员参与通信需要身份认证来确保身份的真实性。为了实现气象数据中密钥协商和身份认证,文章研究了基于身份认证的非对称群组密钥协商协议,利用身份认证和安全分层来使协议更加安全可靠,并最终完成气象数据在群组内信息的安全加解密。With the rapid development of meteorological information technology,meteorological information security has become a key research point.The key negotiation protocol can generate a common session key to ensure the security of encryption and decryption of meteorological information in the group.Group members need identity authentication to ensure the authenticity of their identities.In order to realize key negotiation and identity authentication in meteorological data,this paper studies the asymmetric group key negotiation protocol based on identity authentication,uses identity authentication and security layer to make the protocol more secure and reliable,and finally completes the security encryption and decryption of meteorological data in the group information.
