What is EAP-SIM Key Agreement Analysis about?
EAP-SIM aims to provide 128-bit security for authentication and key agreement but is flawed. It only achieves 64-bit security despite using multiple 64-bit GSM cipher keys (Kc). An attacker can guess one Kc with 1/264 probability and impersonate the authenticator. The document proposes improving this to 96-bit security by including the SRES value. Additionally, EAP-SIM lacks session independence since compromise of a Kc allows impersonation across sessions. There is no complete solution while relying on GSM
