Secure Key Management

Definition ∞ Secure Key Management is the comprehensive process of generating, storing, protecting, using, rotating, and destroying cryptographic keys throughout their lifecycle. This critical security practice ensures that only authorized entities can access and utilize sensitive data or digital assets. Effective key management is essential for maintaining the confidentiality, integrity, and authenticity of digital communications and transactions.
Context ∞ In the digital asset world, secure key management is paramount because private keys control access to cryptocurrencies and other blockchain-based assets. Loss or compromise of a private key results in irreversible loss of funds. Innovations like multi-party computation (MPC) and hardware security modules (HSMs) are improving key management practices for both individuals and institutions, balancing security with usability and recovery options in an environment prone to cyber threats.
