ABSTRACT:
A system and method of protecting data on a communication device are provided. Data received when the communication device is in a first operational state is encrypted using a first cryptographic key and algorithm. When the communication device is in a second operational state, received data is encrypted using a second cryptographic key and algorithm. Received data is stored on the communication device in encrypted form.
