Abstract
Method, device and computer program product for managing a plurality of encryption keys using a keystore seed that defines a seed bit set. A key management process defines a key mapping between the seed bit set and the plurality of encryption keys. The key management process enables each encryption key to be generated from the seed bit set using a corresponding keying material value and the key mapping. The key mapping specifies that an encryption key is generated by partitioning the seed bit set into a plurality of seed bit partitions, determining a keying value from the keying material value, determining a key sequence using the plurality of seed bit partitions and the keying value, and determining the encryption key from the key sequence. Management of a large number of encryption keys can be simplified through indirect management via the keystore seed and the key management process.
