Abstract
A technique for securing on-board bus transactions in a computing device is discussed. A shared key is generated and then programmed into the read-only non-volatile write-once storage of two on-board components. The shared key may be generated during the manufacturing process. Once complete, all transactions between the two on-board components are encrypted by the components using the shared key without exposing the key on any external bus.
