Key Management

Definition ∞ Key management refers to the systematic process of generating, storing, distributing, using, safeguarding, and revoking cryptographic keys. In the context of digital assets, this primarily involves the secure handling of private keys, which grant access and control over cryptocurrencies. Effective key management is fundamental to digital asset security.
Context ∞ The security of private keys is a paramount concern, and news often highlights instances where inadequate key management practices have led to substantial asset theft. Solutions range from hardware security modules (HSMs) to multi-signature schemes, each with its own risk profile and operational considerations. Robust key management protocols are essential for institutional adoption and individual security.
