Design of Security Isolation Card Based on Extended ROM
Zeng Guangyu · Jisuanji gongcheng · 2008
Now,as vulnerability scanning can not fully check out complex attack existing in network,many of the traditional security technologies are no longer valid and failure to prevent effective solutions to modern network security problems from information technology,so many methods based on security model are presented.This paper analyzes the PCI extended ROM specification,the mechanism of network communications link switch,the principle of secret information storage,the connection relation of host computers and devices and the characteristic of attack,presents a novel security architecture of network terminal,which is based on extended ROM and PCI bus to carry out the physics gap of a network terminal between interior and exterior network.It discusses the principle and hardware design of the security isolation card based on PCI bus.
