基于混合加密的融合网络安全认证计费方案

Hybrid Encryption - Based Secure Authentication and Accounting Scheme for Integrating Networks

蜂窝网和Ad Hoc网是提供接入服务的重要技术。由于两者互补的特性,融合蜂窝网和Ad Hoc网能提供在热点地区和通信盲区的持续接入。但两者的融合涉及到许多问题。针对安全问题,在Ad Hoc辅助式的融合网络模型上提出一种基于混合加密的安全认证计费方案。此方案使用对称加密和非对称加密的混合加密机制,另外还采用了散列函数和数字签名技术。安全分析表明所提方案可以防止扮演攻击、重播攻击和中间人攻击,并具有反拒认特性。

Cellular mobile networks and Ad Hoc networks are two important technologies for providing seamless access service. Due to their complementary properties, integrating cellular mobile networks and Ad Hoc networks can offer access to mobile users and ubiquitous connectivity in spite of hotspot areas or blind areas of communication. The integration of the two heterogeneous networks involves several issues. In terms of security, a secure authentication and accounting scheme for Ad Hoc - aided integration networks based on hybrid encryption is proposed. Security analysis shows that this scheme, with non - reputation property, utilizing not only symmetric and asymmetric cryptography, but hash functions and digital signature, can circumvent impersonation attack, replay attack and man - in - the - middle （MITM） attack.
