Abstract
A technique for using a key repository to store data encryption keys provides a way to access key records in the key repository using a key identifier constructed from a media identifier associated with a data storage medium on which encrypted data is or will be stored. The media identifier is hashed and added to a counter value to produce the key identifier. In some embodiments, the technique is implemented in an encryption switch that provides data-at-rest encryption for a storage access network, but in other embodiments, the technique may be implemented in other devices, including data storage devices and hosts.
