Hardware Security Module (HSM) A hardware security module (HSM) is a physical computing device that protects digital key management and key exchange, and performs encryption operations for digital signatures, authentication and other cryptographic functions. It can be thought of as a “trusted” network computer for performing cryptographic operations. A HSM is secure because it: Is […]
