Design and Implementation of Network CryptoGate

چکیده
As the commercial use of the Internet becomes common and the demand for mobile computing through the Internet is emerging, it is necessary to construct a secure mobile environment. This paper presents an implementation example of such a system: "Network CryptoGate (NCG)", which employs the IETF/Mobile IP and the IETF/IP security on stationary security gateways (NCG servers) and mobile hosts (NCG clients). Using IP security primitives, both packets going into a corporate network and packets going out of the visiting network are securely guarded. This IP security based packet control allows transparent mobile access from anywhere on an IP network with su cient security support by encrypting and authenticating IP packets. Currently the NCG system is implemented on BSD/OS, Solaris and Windows NT/95. Preliminary performance measurements show that the proposed NCG's IPsec and Mobile IP processings are sufcient in the current Internet environment.

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
