Single Sign-On Authentication Model using MAS(Mu1ti-Agent System)

Absnnct-The rapid expansion of the Internet has provided users with a diverse range of semces. Most Internet users create many different IDS and passwords to subscribe to various Internet services. Thus, the SSO system has been proposed to supplement vulnerable security that may arise from inefficient management system where administrators and nsers manage a number of I D S . The SSO system eau provide heightened efficiency and security to users and administrators. Recently commercialized SSO systems iutegrate a single agent with the broker authentication model. However, this hybrid anthentication system caunot resolve problems such as those involving user pre-registration and anonymous users. It likewise cannot provide non-repudiation service between joining objem. Consequeutly, the hybrid system causes considerable security vulnerability. Since it cannot provide security semce for the agent itself, the user's private information and SSO system may have significant security vulnerability. This paper proposed an authentication model that integrates a broker anthentication model, out of various authentication models of the SSO system, with a multi-agent system. The proposed method adopts a secure multi-agent system that supplements the security wlnerability of an agent applied to the existing hybrid authentication system. The method proposes au SSO authentication model that satisfies various security requirements not provided by existing broker autheutication models and hybrid authentication systems.
