提出了一种新的无线网络跨域认证协议。在通信过程中,使用对称密码体制来保障消息的机密性、完整性和不可抵赖性,对称密码体制比非对称密码体制的效率更高。理论分析和比较结果证明,该跨域认证协议安全且高效。 Proposed a new wireless network cross-domain authentication protocol. In the process of communication, the symmetric cryptosystem is used to protect the confidentiality, integrity and non-repudiation of the message. The symmetric cryptosystem is more efficient than the asymmetric cryptosystem. Theoretical analysis and comparison results show that the cross-domain authentication protocol is safe and efficient.
