Function Documentation

int eap_sake_compute_mic (  const u8 *  tek_auth, const u8 *  rand_s, const u8 *  rand_p, const u8 *  serverid, size_t  serverid_len, const u8 *  peerid, size_t  peerid_len, int  peer, const u8 *  eap, size_t  eap_len, const u8 *  mic_pos, u8 *  mic )

Compute EAP-SAKE MIC for an EAP packet. Parameters: tek_auth  16-byte TEK-Auth rand_s  16-byte RAND_S rand_p  16-byte RAND_P serverid  SERVERID serverid_len  SERVERID length peerid  PEERID peerid_len  PEERID length peer  MIC calculation for 0 = Server, 1 = Peer message eap  EAP packet eap_len  EAP packet length mic_pos  MIC position in the EAP packet (must be [eap .. eap + eap_len]) mic  Buffer for the computed 16-byte MIC Definition at line 326 of file eap_sake_common.c.

void eap_sake_derive_keys (  const u8 *  root_secret_a, const u8 *  root_secret_b, const u8 *  rand_s, const u8 *  rand_p, u8 *  tek, u8 *  msk, u8 *  emsk )

Derive EAP-SAKE keys. Parameters: root_secret_a  16-byte Root-Secret-A root_secret_b  16-byte Root-Secret-B rand_s  16-byte RAND_S rand_p  16-byte RAND_P tek  Buffer for Temporary EAK Keys (TEK-Auth[16] | TEK-Cipher[16]) msk  Buffer for 64-byte MSK emsk  Buffer for 64-byte EMSK This function derives EAP-SAKE keys as defined in RFC 4763, section 3.2.6.
