The Design And Implementation Of High Intelligent Building Security System

Intelligent building is a combination of modern information technology and traditional building technology. It integrates the intelligent information security management system, building as the basic platform, combining with the construction equipment, network communication system and office automation system.It is the most optimal combination of information, networks, systems, construction and management.Computer information technology is intelligent buildings and other architect ural applications in key technologies. In various parts of the system in intelligent buildings, various types of equipments use the Internet network to achieve transmission, sending and receiving control commands and data collection of information.This paper describes some of the current problems in intelligent building systems exist in the network information security,and analyzes the feasibility of passwords and other information security technology in the intelligent building system applications,and presents a series of security measures based on Public Key Infrastructure PKI technology, combined with practical engineering, implementation of PKI in intelligent building systems, in terms of both hardware and software to build a series of intelligent building information security protection. The main contents include:1.In the intelligent building system has realized the PKI public key infrastructure technology. We protect the information security in intelligent building system by using PKI technology, password security algorithms to ensure data secrecy, integrity, authentication and non-repudiation.2. Use the public key infrastructure technology to access system for safety equipment. In order to be able to access devices for the safety certification, reliable security center will give legal equipment safety certificate, no safety certification of equipment access system will be prevented from access, and to achieve reliable transmission of information between devices.3. Put forward a concept for the security client. In my Paper,we use the CPU smart card as security client device which contains the USB port. The security client makes it easy to implementate the personnel PKI deployment in the intelligent building system. O n the basis of this fact that the traditional firewall do not prevent the attack form the inside,so we puts forward the constructing PKI in the intelligent building system solutions. we use the device authentication switch, trusted computing, security client popular security technology to solve the effective legal status of authentication access equipment and professional technical personnel and convenient implementation of PKI.
