Patent ID: 8351445

Claim:
A network interface system for interfacing a host system with a network to provide outgoing data from the host system to the network and to provide incoming data from the network to the host system, the network interface system comprising: a bus interface system coupleable with a host bus in the host system, the bus interface system being adapted to transfer data between the network interface system and the host system; a media access control system coupleable with the network, the media access control system being adapted to transfer data between the network interface system and the network; a memory system coupled with the bus interface system and the media access control system, the memory system being adapted to store incoming and outgoing data being transferred between the network and the host system; a security system coupled with the memory system, the security system being adapted to selectively encrypt outgoing data and to selectively decrypt incoming data; and a checksum system coupled with the memory system and the bus interface system, the checksum system being adapted to selectively generate checksum values for outgoing data as the outgoing data is being stored in the memory system.
