Authentication method in SWIM based on improved Diameter/EAP-MD5
system wide information management)采用面向服务的体系结构(SOA
service oriented architecture)提供民航信息交互与数据共享功能。在分析SWIM体系结构和基于Diameter协议的EAP-MD5应用子协议基础上,给出标准Diameter/EAP-MD5认证过程中存在的安全隐患,改进了EAP-MD5认证协议,提出基于改进的Diameter/EAP-MD5协议的SWIM用户身份认证方法,研究基于Diameter的SWIM认证服务,并在模拟的SWIM环境中对改进方法进行仿真实验和安全性分析。实验结果表明,改进的Diameter/EAP-MD5认证方法可在计算性能相当的前提下提高SWIM认证系统的安全性,为SWIM安全服务框架的构建提供保障。
Abstract
System wide information management (SWIM) provides the civil aviation information exchange and data sharing function by using service-oriented architecture (SOA). Based on the analysis of SWIM architecture and the sub-protocol EAP-MD5 of Diameter
the security vulnerable of authenticating process in standard Diameter/EAP-MD5 is explored
the EAP-MD5 authentication protocol is improved
and the SWIM authentication service based on Diameter is studied
then the SWIM authentication method based on improved Diameter/EAP-MD5 protocol is proposed. Experi-ments on the security of SWIM authentication service based on Diameter are performed in SWIM simulation environ-ment
results show that the improved Diameter/EAP-MD5 authentication method can enhance the security of SWIM au-thentication and guarantee SWIM security service.
