## Key Management Failure

Key management failure encompasses the entire lifecycle of cryptographic keys, from generation to storage and destruction. In the context of protocols, this often means failing to secure private keys against unauthorized access.

Common failures include storing keys in plaintext, using weak hardware security modules, or failing to implement proper backup and recovery procedures. If keys are lost or stolen, the protocol is effectively compromised.

Robust key management is the foundation of security for any decentralized system relying on private key authentication.
