between these parties. This Standard defines MAC that uses acryptographic hashfunction in conjunction with a secret key. This mechanism is called HMAC. HMAC shall use an Approved cryptographic hash function [FIPS 180-3]. HMAC uses the secret key for the calculation and verification of the MACs....
Section 5 defines the constants and the composite functions used to specify the hash algorithms. Section 6 gives the actual specification for the SHA-224, SHA-256, SHA-384, and SHA-512 functions. Section 7 provides pointers to the specification of HMAC keyed message authentication codes and to...

Wasef and Shen [72], [73] try to reduce the time involved in checking the CRLs during message authentication; they use the keyed Hash Message Authentication Code (HMAC), wherein the key used to calculate the HMAC is shared only between non-revoked OBUs. However, vehicles must still verify...

Sessions are immutable (each save generates a new session), and lockless. Session data is AES-256-GCM encrypted with a key derived using HKDF-SHA256 (on FIPS-mode it uses PBKDF2 with SHA-256 instead. Session has a fixed size header that is protected with HMAC-SHA256 MAC with a key ...
