Authentication and Ciphering Algorithms in GSM

WebFor 2G authentication, AuC keeps the Ki, authentication algorithm (have A3, A8 functions) and generates the random number (RAND). 3GPP /GSM provides a specification for the authentication algorithm. AUC for GSM 2G, sim cards send the triplet to MSC (or SGSN). Each triplet has RAND, Kc, and SRES. A3 (Ki, RAND) -> SRES, A8 (Ki, RAND) = Kc. WebEncryption key for protection of RRC data derived in eNB and UE. All LTE security keys (EPS) are 256 bits in length. The ciphering and integrity keys for AS and NAS algorithms use only the 128 LSB (Least Significant Bits) of the derived keys. For more detailed information on key derivation and key hierarchy refer 3GPP 33.401 document. simplisafe wireless frequency https://connersmachinery.com
