Cryptographic key management involves the secure generation, storage, distribution, usage, and destruction of cryptographic keys. These keys are fundamental for securing digital assets and communications. Proper management ensures the confidentiality, integrity, and authenticity of data. Inadequate key management presents a significant security vulnerability for any system relying on cryptography.
Context
Cryptographic key management remains a paramount concern in the digital asset sector, with ongoing discussions about best practices for institutional and individual holders. Hardware Security Modules (HSMs) and multi-party computation (MPC) are key areas of development to enhance security. News frequently reports on advancements in secure key storage and recovery solutions.
Expander Signatures, a novel cryptographic primitive, decouple heavy key generation from constant-size, lightweight verification, solving the key management burden for IoT devices on-chain.
