Wireless medium is open to all. Hence it is always acceptable to threats and attacks. GSM being a wireless network is always prone to the unauthorized access to the network and entrustment to the privacy and confidentiality of the users. Therefore, the GSM provides security measures to ensure the privacy and confidentiality of the users to ensure that only registered and authorized users get the access to the network. This paper briefly presents the security measures of GSM technology. The study is enriched with a general overview of GSM protection and the algorithms that are mainly used in A3, A5 and A8. Author’s also discussed the authentication and encryption methods provided by GSM. A3 for MS authentication algorithm. A5 for powerful over wind voice privacy algorithms. A8 for voice privacy key generation algorithm.
