CryIf

Definition

CryIf: AUTOSAR Crypto Interface — abstraction between CSM and the underlying crypto driver. CryIf decouples CSM clients from the specific crypto driver in use (HSM, software).

Where this matters: AUTOSAR Development — Crypto Stack, SecOC and HSM integration

Each crypto primitive is mapped to a channel/key/algorithm triple via CryIf configuration, so changes in the driver layer don't require recompiling consumers.

Related terms

AUTOSAR module that exposes cryptographic services to upper layers.
Hardware Security Module (HSM)
