A unique transaction key (Tk) is established amongst multiple entities using a common hardware security module (HSM) with a common HMAC key (HK) and transaction scheme name (T). The transaction key (Tk) can be used for various cryptographic functions (e.g. encryption, MAC, HMAC, key management) with one or more messages at the transaction or session level.
