Hardware Security Modules (HSMs)

Definition

Hardware Security Modules (HSMs) are physical devices specifically designed to manage and safeguard cryptographic keys and perform cryptographic operations securely. These modules provide a high level of security for sensitive data by ensuring that cryptographic keys are generated, stored, and used in a secure environment, thus playing a crucial role in the implementation of secure systems, including those used for Quantum Random Number Generation (QRNG). HSMs are integral in various applications, enabling the protection of data integrity, confidentiality, and authentication processes.
