Abstract
Key generation and roll over is provided for a cloud based identity management system. A key set is generated that includes a previous key and expiration time, a current key and expiration time, and a next key and expiration time, and stores the key set in a database table and a memory cache associated with the database table. At the current key expiration time, the key set is rolled over, including retrieving the key set from the database table, updating the previous key and expiration time with the current key and expiration time, updating the current key and expiration time with the next key and expiration time, generating a new key and expiration time, updating the next key and expiration time with the new key and expiration time, and updating the key set in the database table and the memory cache.
