【摘要】 针对Kerberos认证协议由对称算法所带来的局限性,国内外已有很多人用以RSA算法为代表的公钥体制对Kerberos协议进行了改进。本文选用ElGamal算法来修正Kerberos协议,一箭双雕,不仅继承了先行者们的研究成果,而且彻底解决Kerberos可能窃听通信双方会话的问题。因此,更具安全性、实用性。更多还原

【Abstract】 To overcome the Kerberos’ limitations caused by using symmetric algorithm,many people home and abroad have improved Kerberos protocol with public-key algorithm represented by RSA.ElGamal algorithm is combined with the purpose to not only inheriting attained research achievements but also completely solving the problem of that Kerberos can intercept and see the information from two communicating sides with session key.In comparison with Kerberos RSA,it provides more security and practicality.更多还原
