Abstract

The invention discloses an authentification method of a communication system. The device comprises a request module, a transmitter module, an identifying and processing module and an authentification module, wherein, the request module is used for the user to send an access request to a system through the terminal; the transmitter module is used for a call session control server on the system side to receive the access request and to send an authentification request message to an HSS; the identifying and processing module is used for the HSS to receive the authentification request message and to judge whether the times of the authentification request in a presetting time period are up to the presetting times as well as sending the message including the judged result to the call session control server; the authentification module is used for the call session control server to authenticate the user according to the message. The invention can maintain the authority and the security of a legal user and can have good compatibility.

Description

technical field [0001] The present invention relates to the field of communication, and in particular, to an authentication device in a communication system. Background technique [0002] Because IP technology has a series of advantages such as interoperability, the communication system is gradually changing to IP bearer. The resulting network convergence has led to the birth of a new generation of network communication standard - IMS. Due to the openness of IP technology, the security requirements of communication networks have reached unprecedented heights. The challenge-response-based bidirectional authentication mechanism has become a mainstream method for authenticating terminals or networks in communication systems. IETF's RFC3310 standard organically combines the authentication mechanism in the traditional IP field represented by RFC2617 with the authentication mechanism in the mobile field represented by the 3GPP 33.102 protocol. With the convergence of the network...
