Abstract: This paper studies the common hardware architecture of encryption network card. According to complex control and difficult design of stream architecture, it brings forward a multiple hardware architecture, which reduces the design difficulty and the control complexity, and designs the prototype card of encryption network card based on this architecture. A lot of data test shows the whole architecture achieves a good balance between performance and efficiency.

Key words: encryption network card, Ethernet, finite-state machine, local bus
