One-way Transmission Tunnel Based on Bell-LaPadula Model
Shuhui Chen · 2012
In the situation of physical isolation,data can only be transmitted from the low security level network to the high one to ensure the safety of the internal network.Without message feedback,one-way network protocol makes the traditional database synchronization technology unusable,and it is very easy that information loss or information error in the transmission process occur frequently.To solve these problems,this paper analyses the BLP model,and presents a safe and reliable solution in the one-way synchronization of database and high reliable transmission.The availability analysis for the one-way transmission tunnel based on our solution is also provided.
