CSM (Crypto Service Manager)

Also known as: Crypto Service Manager

AUTOSAR module that exposes cryptographic services to upper layers.

AUTOSAR Crypto Service Manager (CSM) is the application-layer entry point for encryption, signing, MAC, hashing, and random-number services. CSM dispatches to the CryIf abstraction, which routes calls to an HSM-backed crypto driver or a software crypto library.
