TRSM

TRSM

A Tamper-Resistant Security Module is a device that encorporates physical protections to prevent compromise of Cryptographic Security Parameters (CSP) therein contained.

There are varying levels of protection afforded by TRSMs:
# Tamper-resistance: make intrusion difficult, usually by employing hardened casing
# Tamper-evident: make intrusion attempts evident to subsequent viewers, often by employing seals which much be broken during intrusion
# Tamper-responsive: detect the intrusion attempt and destroy the contents in the process

A TRSM is usually also a HSM.
