Which of the following is a physical device used to securely generate, store, and manage cryptographic keys, offering high levels of security for encryption processes?
A Hardware Security Module (HSM) is a physical device that provides secure generation, storage, and management of cryptographic keys. HSMs are designed to protect keys from unauthorized access and are used to enhance security in encryption processes. A Key Management System is typically software-based and manages keys but doesn't provide the physical security level of an HSM. A Trusted Platform Module (TPM) is a hardware-based security chip embedded in devices, used mainly for device authentication and integrity verification rather than comprehensive key management. A Secure Enclave is a secure area within a processor, primarily used in mobile devices to store sensitive data, but it is not a standalone device like an HSM.
