A component of the infrastructure equipment in the GSM network. Its purpose is to validate subscribers logging on to the network. It does this by means of a secret key. The AuC contains a unique key (code) for each subscriber in a network. The subscriber has a copy of this key within the SIM card. A subscriber attempting to log on to the network is sent a copy of a random number by the AuC. The secret key within both the SIM card and the AuC changes their copy of the number. The number produced by the SIM card is returned to the AuC and if it is the same as the number produced by the AuC the subscriber is validated and is allowed access to the network.

Authentication Centre The AUC stores confidential data and keys in a GSM network that are used to provide security.
