Patent ID: 7603322

Claim:
A computer readable medium comprising computer executable instructions for retrieving a value secured in a key management system, the instructions, when executed, causing a processor to perform method steps of: obtaining a decoded key list by decoding an encoded key list, wherein the decoded key list comprises a key corresponding to the value; receiving a request for the value secured in the key management system from a requesting application, wherein the request comprises the key; in response to the request for the value, searching for the key in the decoded key list; determining the key corresponding to the value is in the decoded key list; obtaining an encrypted tuple, encrypted using a key encryption key associated with a key decryption key, from the key management system using the key, wherein the encrypted tuple comprises the key and the value; obtaining a tuple corresponding to the value by decrypting the encrypted tuple using the key decryption key; and providing the tuple corresponding to the value to the requesting application.
