A New Intelligent Security Structure for Host System

There are lots of shortcomings in today' s NIC, and this results in the occupancy of lots of resources in CPU and Memory, greatly affects the responding time of computer and the transmission efficiency of data access, easily exposes the host to the attack and damage from the network and thus keeps the internal data in the host in great insecurity. Accordingly, this paper puts forward an intelligent NIC ' s security structure for independent host; the structure makes host and NIC into two fairly independent data processing modules. After testing, this structure can ensure the security of the host and greatly improve the running efficiency at the same time.
