Abstract
A system for encrypting and decrypting data is provided. The system includes a client for receiving a data packet, setting a value of a crypto bit, and transmitting the data packet over a system bus. A crypto module receives the data packet from the system bus and performs a cryptology function on the data packet based on a first value of the crypto bit. A memory controller receives the data packet from the system bus and performs non-cryptology functions on the data packet based on a second value of the crypto bit.
