Abstract
Techniques are generally described for methods, systems, data processing devices and computer readable media configured to decrypt data to be stored in a data cache when a particular condition indicative of user authentication or data security has occurred. The described techniques may also be arranged to terminate the storage of decrypted data in the cache when a particular condition that may compromise the security of the data is detected. The describe techniques may further be arranged to erase the decrypted data stored in the cache when a particular condition that may compromise the security of the data is detected.
