从形式化处理的角度出发,首先分析了跨域C2C—PAKE协议应该具有的安全属性,然后给出了一个适合于跨域C2C—PAKE协议的安全模型,并推广了单服务器C2C—PAKE协议的通用协议,进而给出了一个跨域C2C—PAKE协议的通用构造,并在新的模型中证明了其安全性。
From the formalism point of view, the security attributes needed in the cross-realm C2C-PAKE scenario was first analyzed, and then a new security model for cross-realm C2C-PAKE was presented. Analogous to the general construction of 3PAKE protocol for single server C2C-PAKE setting, a general construction of cross-realm C2C-PAKE protocol was given, which security was proved in the new security model.
