Abstract

The lock-keeper is a new network security solution which can provide secure data transfers between two different networks without having to establish a direct physical connection. By means of the lock-keeper system, the possibility of direct attacks to the protected network can be eliminated. An actual system, the singlegate lock-keeper, is used as an example to introduce the lock-keeper concept in detail, including its architecture, functionalities, applications, vulnerabilities and benefits. Based on this system, a new advanced dualgate lock-keeper including another "gate" unit is proposed that can provide more efficient and secure data exchange and make extensions of the lock-keeper applications possible.
