StoredKey

StoredKey is a term that can refer to several related concepts within cryptography and computer security, primarily concerning the secure storage of cryptographic keys. At its core, a StoredKey implies a private key or secret that has been saved on a device or system for later use, rather than being generated on the fly and discarded. The primary concern with StoredKeys is ensuring their confidentiality and integrity against unauthorized access or modification.

Different contexts use StoredKey to denote specific implementations. For example, in hardware security modules (HSMs), keys are often generated and stored within the tamper-resistant hardware itself, with access controlled by strict policies. Software-based solutions might involve encrypting keys on disk or within secure enclaves, often protected by a master key or user authentication. The specific method of securing a StoredKey depends heavily on the threat model and the sensitivity of the data it protects. Vulnerabilities can arise from insecure storage mechanisms, weak encryption, or compromised access controls, potentially leading to key compromise and subsequent data breaches.
