Comparative Analysis and Application of Common ...

Through technical analysis and comparison of authentication modes and architecture of commonly used network accounting technology such as PPPoE + Radius, DHCP + WEB + Radius, 802.1X + Radius, Kerberos and SSO, it is revealed in this paper that Kerberos as a new mode is suitable for the application of Web network system identity Authentication; while in many cases SSO can access all the mutually trusted application system by means of a single login; and in modern broadband Ethernet access, optimized IEEE 802.1x protocol + Radius server authentication mode is recommended, which can solve the bottleneck problem of the traditional authentication methods such as PPPoE and Web / Portal.
