Security system for surveillance radar network communication using chaos algorithm

摘要

Surveillance radar network is the network of some radar station to monitor and keep watch ship/vessel traffic. The communication of these station used tcp/ip over internet and local area network. The security system is an important part that can not be ignored for network communication. This paper proposed a prototype of security system for surveillance radar network, which is handling the security of communications over the Internet between a radar station to master station. The system is designed to protect the radar data against unauthorized parties. From the previous work, there was a weakness in the pseudorandom number generator. The generated number could not satisfy the randomness, it might be raise a security problem. Thus, Pseudorandom Number Generator (PNRG) using chaos algorithm was added to strengthen the salt cryptographic scheme. The analysis of result will be discussed to obtain the advantages of new system. Finally, a layered security system has been developed by taking advantage of a variety of encryption algorithms to get the best protection for the security of surveillance radar network communication.
