In this paper,we simply introduces the whole design scheme of security network access server; subsequently, we deeply analyse the principle and structure model of RADIUS and TACACS in the distributed security authentication system, and more explain the idea and implementation of design. On the other hand, in order to authencating、authorizing and accounting more securely, efficiently and accurately to the remote users, we put forward a series of key techniques which are used in analysis such as MD5 encryption arithmetic、packet retransfer、buffer storage、interprocess communication and so on, and prove the compatibility of the system through employing the commercial software Shiva AccessManager.
