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.
