The Design and Implementation of a Hot Switch Isolation Circuit Card

Abstract:

To protect the security of critical data and application system, generally, many companies or departments use a parallel way of intranet and internet. Because every kind of security technology has its limitations, traditional security products such as firewall, VPN, data encryption, intrusion detection and network vulnerability scanning can not completely solve various security problems in information exchange between different networks. It is not able to meet all the security needs of critical networks and security data with the general products only. The way of data exchange of most of the existing products of "GAP" is mainly logic isolation .This paper describes a design and implementation of a hot switch circuit card in way of physical isolation .The data exchange mode of this circuit card is a half-duplex which can physically completely isolate intranet and internet. Through functional test and performance test, we can draw a conclusion that the circuit card can effectively achieve our demand of data exchange between different networks.
