A Novel Approach for Authentication Technique in Mobile Communications

Abstract :-
Authentication of mobile subscriber is a challenge of future researchers due to increasing security threats and attacks with the enhanced population of wireless traffic. 3G mobile communication system has been developed to speed up the data communication. In general the authentication technique in 2G mobile communication is solely dependent on checking the authenticity of MS (Mobile Station or Subscriber) by challenge/response mechanism. Here authenticity is one-way for which MSC (Mobile or Main Switching Center) checks the validity of MS. 3G mobile communication works on two different switching techniques. One is circuit switching for voice and low speed data communications. Continue reading A Novel Approach for Authentication Technique in Mobile Communications
