eap_sake_kdf - EAP-SAKE Key Derivation Function (KDF) : Key for KDF : Length of the key in bytes : A unique label for each purpose of the KDF : Extra data (start) to bind into the key : Length of the data : Extra data (end) to bind into the key : Length of the data2 : Buffer for the generated pseudo-random key : Number of bytes of key to generate
This function is used to derive new, cryptographically separate keys from a given key (e.g., SMS). This is identical to the PRF used in IEEE 802.11i.
