Secure data storage and access during transition operations

Abstract:

A technique for secure data storage and access during transition operations includes retrieving an encrypted instance of a data object from a data store. The retrieved encrypted instance of the data object is stored in a cryptcache. The encrypted instance in the cryptcache is decrypted to a cleartext instance of the data object and stored as the cleartext instance of the data object in a clearcache. The clearcache instance of the data object is secured by controlling an access window defining an amount of time the cleartext instance of the data object is accessible in the clearcache.
