Security products in the access control system explains the technology and encryption technology

About IC card encryption cracking problem incredibly, the Ministry of information industry publishing relevant information, for a day of back door access system and card system in key departments and agencies on the prohibition of the use of IC card as identification card, the billing card.

Therefore, many access control manufacturers have changed the original design.

Mainly used the CPU card reader and the corresponding CPU card, and then do the encryption and decryption algorithm.

Some manufacturers consider the IC card and CPU card compatibility problems, but also in the design of appropriate software that incompatible, but reader hardware compatibility problem is still in the research and development, compatible software is relatively easy to achieve.

Access control system the most important thing is to prevent cracking encrypted card, identification and control of relative is relatively easy to do, so for card performance is crucial.

The card, the appropriate use of different hardware standard match, at the same time, companies use the card inside, design your own encryption algorithms, and is also the core of the company's technology, how to have a reliable and secure software and hardware technology is the key to door manufacturers.

With the rapid development of computer technology, a newly developed door systems all use a high-performance processing chip, such as the ARM9, ARM7 series chip using a technique based on TCP/IP, front-end reader uses the current security the highest CPU card reader and CPU card, but this is only a short period of technology at present.

Modao a foot, road climbs, no matter how reliable encryption taken, will have the chance of a break, just the time and cost, but as a means of improving science and technology, explains the cost and time is getting low.

Therefore, security improvements only is based on the development of biotechnology to final settlement cracking the encryption of the challenge.

Using living fingerprint technology, vein recognition technology, face recognition, iris recognition technology, DNA identification technology, even some the biometric technology is combined with the use of access control system is the ultimate technology development direction.

Although now have such access control system, but the cost is very high, thus lowering the cost of the biometric sensor and improve recognition technology is the next major technical difficulties. It contains math, biology, physics, sensors, optics, computer and other high-tech means that only a joint development to implementation.
