Abstract
Key management for encrypted data. A node, such as a storage device, obtains a shared key to be used in cryptographic operations. The obtaining includes using an identifier of another node, such as a host of the computing environment, and a unique identifier of the shared key to obtain the shared key. The obtained shared key is then used in one or more cryptographic operations.
