Abstract: A computing device has a security module that (i) receives a request to decrypt encrypted data; (ii) sets up an uninterruptible timer based on a specified time interval; (iii) decrypts the encrypted data to generate and stores corresponding decrypted data in a memory within the computing device; and (iv) provides a trigger signal to delete the decrypted data from the memory after expiration of the specified time interval as determined by the timer. The security module limits the duration that the decrypted data is stored in the memory and thus reduces the chance the data can be subject to unauthorized accessed.
