WebMany algorithms are used for making the GSM secure. The algorithms mainly used are A3, A5 and A8 algorithms. Algorithm A3 is used for authentication, A5 is used for encryption, and A8 is used for the generation of a cipher key. This paper presents an … WebJun 25, 2014 · We solved the GSM problem in A3 algorithm such as eavesdropping and this problem solved by CL-PKC because of its robustness against this type of attack by providing mutual authentication make the system more secure. Recent years, the mobile technology has experienced a great increment in the number of its users. The GSM’s …

For details on the way A3 and A8 are used see Authentication Center. A3 and A8 both take a 128-bit key (Ki) and a 128-bit challenge (RAND) as inputs. A3 produces a 32-bit response (SRES) and A8 produces a 64-bit session key (Kc). A3/A8 is the combined function with Ki and RAND as inputs and SRES and Kc as outputs. As A3 and A8 are not further specified, operators can freely choose the concrete algorithms use… WebA8Ciphering Key Generating Algorithm A8. This algorithm is used in conjunction with Ki , the authentication key, and RAND (Random Number) to generate Kc (Cipher Key). This is used with A5/X to cipher the data stream between the MS (Mobile Station) and the GSM network.
