摘要:

针对传统1-to-1和m-to-1认证模式中认证密码容易泄露的安全隐患,提出一种m-to-n认证模式。系统认证时,由m个客户端同时向n个认证服务器发起认证请求,将该认证模式抽象为安全两群体计算模型,并定义其在半诚实模型下的安全性。构造一个安全多方求和协议,并以该协议为基本构建模块,将健忘传输协议作为基本密码工具,设计安全两群体认证协议。分析结果表明,该协议安全性和效率较高,能够解决两群体群体内及群体间的安全认证问题

关键词: 安全多方计算, 安全两群体计算, m-to-n认证模式, 半诚实模型, 健忘传输协议

Abstract:

In order to solve the problem that the authentication cipher security risk of the traditional 1-to-1 and m-to-1 authentication mode is easier to leak,the paper proposes a m-to-n authentication mode,which includes m clients and n authentication servers.m clients request to n servers at the same time.In this mode,m clients and n servers are abstracted as the secure two-group computation model.It defines the model security under the semi-honest model,puts forward a security multi-party summation protocol.Taking the security multi-party summation protocol as the basic building block and the forgetfulness transfer protocol as the basic cryptographic tool,this paper designs a secure two-group authentication protocol.Analysis results show that this protocol has higher security and efficiency,it can solve the problem of security authentication between intra group and inter group .

Key words: secure multi-party computation, secure two-group computation, m-to-n authentication mode, semi-honest model, forgetfulness transfer protocol
