一种基于点集拓扑分形变幻的云计算登录认证方法

A CLOUD COMPUTING LOGON AUTHENTICATION METHOD BASED ON POINT SET TOPOLOGY FRACTAL CHANGE

考虑到云服务登录安全性及便捷性的需求,针对单点登录认证模式,提出云计算的统一登录认证方法,并采用点集拓扑分形变幻方法生成随机密钥,提高登录认证的安全等级。首先对云计算登录认证系统结构进行分析,然后以网络公共数据库中的指纹图像为例,进行分形变幻环运算,生成伪随机序列,再将这些序列加密并通过UDP发送给服务器端进行认证,最后进行实例仿真。

Considering the safety and convenience demand of cloud service logon,we put forward a uniform logon authentication method for cloud computing aiming at the single sign-on authentication mode,and use point set topology fractal change method to generate random key for improving the logon authentication safety grade.First,we analyse the cloud computing logon authentication system structure,the next,we use fingerprint image in network public databases as the example do carry out fractal change ring operation,and generate a pseudo-random sequences,then these sequences are encrypted and sent to the server through UDP for authentication.Finally,we make a simulation with real example.
