GSM is the most secured cellular telecommunications system available today. GSM has its security methods standardized. GSM maintains end-to-end security by retaining the confidentiality of calls and anonymity of the GSM subscriber. The first step in the GSM security is the authentication of a valid user for the SIM (Subscriber Identity Module) [SIM stores all user-specific data that is relevant to GSM.]. The user needs a PIN to access the SIM. PIN is the Personal Identification Number. The next step is the subscriber authentication. This step is based on the challenge-response scheme. Later steps are encryption and

Unlike GSM, which has authentication of the user to the network only, UMTS uses mutual authentication which means the mobile user and the serving network authenticate each other, providing security against false base stations. This mutual authentication uses an authentication quintet which helps to ensure that a bill is issued to the correct person. The authentication quintet consists of the GSM is the most secured cellular telecommunications system available today. GSM has its security methods standardized.
