Key Escrow Component (KEC).The KEC, which is operated by key escrow agents, manages the storage and release or use of data recovery keys.It may be part of a public key certificate management system or part of a general key management infrastructure. Data Recovery Component (DRC).The DRC consists of the algorithms, protocols, and equipment needed to obtain the plaintext from the ciphertext plus information contained in the DRF and provided by the KEC.It is active only as needed to perform a specific authorized data recovery.
