摘要
单点登录系统对于信息的安全保密性要求很高,而信息高保密性实现的难点是如何在现代发达的网络技术条件下对非法的登录访问实现隔离。提出一种基于改进Kerberos协议的对称密钥下虚假身份认证方法,在对称密钥约束下,采用Kerberos协议解密的方法对访问用户的登录信息进行深层次识别和判断,并且与数据库中的身份特征相互比较,如果满足设定的门限要求,则认定为正常登录,否则,拒绝登录。采用某企业实际的访问数据进行测试实验,结果显示,采用基于改进Kerberos协议的对称密钥下虚假身份认证方法,虚假身份的识别概率提高了25%,具有很好的应用价值。
The single sign-on system required high security and confidentiality, and the most difficult thing of security was how to isolate illegal login access in modern network technology. So a high recognition rate method of false authentication based on Kerberos protocol under symmetric key was proposed, the Kerberos protocol was used to access the user＇s login in-formation to identify and determine the depth, and the identity and characteristics of each database was compared, if the set threshold requirements was met, it was identified as normal login, otherwise reject login. Data of an enterprise was used to do the actual experiment, and the result shows that with the Kerberos protocol method, the false identity recognition proba-bility increase by 25%, it has good application value.
