A tamper-resistant security module (TRSM) is a device that incorporates physical protections to prevent compromise of cryptographic security parameters that it contains.
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 must be broken during intrusion
# Tamper-responsive: detect the intrusion attempt and destroy the contents in the process
A TRSM is usually also a
hardware security module
