Abstract

Key derivation function (KDF) is used to generate security key in LTE network. For MD5 and SHA1 algorithms in LTE networks shortage, this paper presented an approach KDF based on HMAC-SHA-256(Hashed Message Authentication Code, Secure Hash Algorithm) algorithm. HMAC_SHA is a secure cryptographic hash function-based message and shared key authentication protocols. It can effectively prevent data being intercepted and tampered with during transmissions, maintain data integrity, reliability and security.
