name: AUC
full_form: Authentication Centre
context: An intruder who gains direct access to an AuC can effectively clone all subscribers whose data he had access to. Number of employees having physical and logical access to AuC should be limited. From security point of view it is then reasonable to use an AuC which is not integrated with HLR. Operators should carefully consider the need for encryption of AuC data. Some vendors use default encryption, the algorithm being proprietary and confidential. It should be noted that strength of such encryption could be questionable. If decided to use an add-on ciphering facility, attention should be paid to cryptographic key management. Careless use of such equipment could even lower AuC security. Authentication triplets can be obtained from AuC by masquerading as another system entity (namely HLR). The threat is present when HLR and AuC are physically separated.
description: The Authentication Centre (AUC) is a network function responsible for storing and managing subscriber authentication data, including encryption keys and algorithms. It plays a critical role in ensuring the security of the mobile network by authenticating users and protecting against unauthorized access.
explanation: The context describes the AUC's functions within the mobile network infrastructure, emphasizing its role in authentication and security. This aligns with the definition of a Network Function as a component responsible for specific tasks within a telecommunications network.
