Abstract
A network processor provides for in-line encryption and decryption of received and transmitted packets. For packet transmittal, a processor core generates packet data for encryption and forwards an encryption instruction to a cryptographic unit. The cryptographic unit generates an encrypted packet, and enqueues a send descriptor to a network interface controller, which, in turn, constructs and transmits an outgoing packet. For received encrypted packets, the network interface controller communicates with the cryptographic unit to decrypt the packet prior to enqueuing work to the processor core, thereby providing the processor core with a decrypted packet.
