Functions of AUC in GSM

In GSM (Global System for Mobile Communications), the Authentication Center (AUC) plays a crucial role in ensuring network security. Its primary functions include generating and managing encryption keys and handling user authentication to prevent fraud. The AUC verifies the identity of users by comparing the response from the mobile device with the expected result based on stored parameters. Additionally, it helps in securing communication by providing encryption algorithms that protect the confidentiality of user data during transmission.
