Web10 May 2024 · UMTS uses a mutual authentication between the mobile and the base station. It relies on a 128 or 256-bit shared secret key K stored in the USIM and the core network. … WebSymmetric key encryption is used to encrypt large amounts of data efficiently. Advanced Encryption Standard (AES) keys are symmetric keys that can be three different key lengths (128, 192, or 256 bits). AES is the encryption standard that is recognized and recommended by the US government. The 256-bit keys are the longest allowed by AES.
