Abstract
Encryption techniques for securing data in a data cache are generally disclosed. Example methods may include one or more of reading the cache to identify data, determining whether the data is encrypted to identify previously unencrypted data and/or previously encrypted data, and encrypting selectively at least a portion of the previously unencrypted data. The present disclosure also generally relates to a computer system data processor configured to read a cache to identify data, determine whether the read data is encrypted, and encrypt selectively at least a portion of the previously unencrypted data. The present disclosure also generally relates to computer accessible mediums containing computer-executable instructions for data encryption upon execution of the instructions by a data processor. The instructions may configure the data processor to perform procedures that read the cache to identify data, determine whether the data is encrypted, and selectively encrypt data determined as unencrypted.
