User authentication protocol for blocking malicious user in Network CCTV environment

In recent days, CCTV study is standing out by coming to the fore. CCTV used to be a method of crime prevention. But, these day, CCTVs are being networked by providing IP addresses and it is exposed to many threats existing in Web Environment. In this paper, it protects user information based on PKI(Public Key Infratructure) and we propose user authentication protocol to prevent unauthorized user access in Network CCTV environment using CCTV unique SN(Serial Number) value which provided when becoming a member and Random number R value which provides every login time. This proposed system is safer than existing system against brute force attack, masquerade attack, replay attack, known key attack, web-site hacking, brute force attack to server secret key, modification and key-board hooking. This proposal will be suitable for user´s privacy violation utilization which is unapplied user information security related technology about CCTV.
