分析了当前虚拟组织中身份认证的单向认证协议和带私有通道的认证协议,指出了这些协议需要参与双方进行多次信息交换,存在认证效率低下且占用大量网络资源与计算资源的弊端.为解决这些问题,提出了虚拟组织中无私有通道的一次认证协议.该协议所有的信息交换均在非安全的公用通道上进行.这种改进的身份认证协议只需一次信息交换便可达到身份认证的目的,信息的交换不需要建立私有通道.同时,给出了改进认证协议的证明,并对这3种协议的特征进行了比较,说明笔者所提出的“改进型的无私有通道一次认证协议”网络开销最小、效率和安全级别最高、实现难易程度最低,是确实可行的、有效的身份认证协议.
This paper analyzes the unidirectional authentication protocol and the authentication protocol with private channel in the current virtual organization. It is pointed out that these protocols need to participate in the exchange of multiple messages between the two parties, which leads to the disadvantage of inefficient authentication and occupy a large number of network resources and computing resources. In order to solve these problems, an authentication protocol with no private channel in the virtual organization is proposed, and all the information exchange of the protocol is performed on the non-secure public channel.The improved authentication protocol can achieve identity authentication with only one exchange of information , The exchange of information does not need to establish a private channel.At the same time, the proof of improving the authentication protocol is given, and the characteristics of the three protocols are compared, which shows that the author proposes “improved selfless channel authentication Agreement ”is the minimum cost of network, the highest level of efficiency and safety, the easiest to achieve, is a viable and effective authentication protocol.
