Identity cards and integrated circuits

The full name of ID card is identification card, which is an unwritten induction card with a fixed number. There are mainly the EM format of SYRIS in Taiwan Province Province and various ID cards such as HIDMOTOROLA in the United States. Like magnetic cards, ID cards only use the "card number". Except for the card number, there is no security function in the card, and its "card number" is publicly exposed. So the ID card is an "inductive magnetic card". The specification of ISO standard ID card is: 85.6x54x0.80 0.04mm (height/width/thickness), and there are some thick, thin or irregular cards in the market.

IC card (integrated circuit card) is also called smart card, smart card, microcircuit card or microchip card. It embeds the microelectronic chip into the card base conforming to ISO 78 16 standard and makes it into the form of a card. The communication mode between IC card and card reader can be contact or non-contact. According to the communication interface, IC cards are divided into contact IC cards, contactless IC cards and dual-interface cards (both contact and contactless communication interfaces).

Because of its inherent advantages of information security, portability and perfect standardization, IC cards are increasingly used in identity authentication, banking, telecommunications, public transportation, parking lot management and other fields. For example, the second-generation ID card, the bank's electronic wallet, the mobile phone SIM card of telecom, the bus card and subway card of public transportation, and the parking card for charging parking fees. Are all in people's daily lives.

Therefore, the security of IC cards is the common sense of ordinary people. However, with the rapid development of chip upgrade, there are always pioneers who break this statement. In recent years, there are two big blocks in the anti-copy market: anti-copy IC and anti-copy ID. Today, I will talk about the new technology on the market from the perspective of copy protection (not new, the copy protection ID came out two years ago). The advantages of IC chips have long existed, but the good cards of anti-copy IC chips have been smashed by some manufacturers. Because of the low barriers to entry, many anti-copy IC chip cards are being made. In order to finally show its face, it has reached the point where it has to fight for the price, and the market is chaotic, so the security level of the anti-copy card has dropped. When the anti-copy ID chip card was first used as a promotion chip, the entry threshold was very high, only for. The management pressure in the market is not so great, so it is unique and the dark horse comes first. Therefore, the security level has risen from the perspective of chips and management. Don't look online, just tell you that it is "Shenzhen Jianhe Smart Card". Look up these words, there will be a bunch of suppliers, most of whom are agents or distributors, all of whom are unified under construction and smart card headquarters to get goods. This anti-copy ID card chip consists of JH letters, including JH4 10 1 and JH4 102 chips. This is a brand-new chip to upgrade the confidentiality agreement. The internal code of JH4 10 1 can be written as serial number chip or customized number segment according to customer requirements. JH4 102 is a chip with key authentication, which can only be accessed by matching a dedicated card reader (which is also built-in and exclusive). You can erase once, but you can't copy. Therefore, a bunch of articles on Baidu said that the ID card is an unwritten induction card, and that there is no confidentiality function, which is a bit embarrassing! The following is more detailed information, from which we can learn a thing or two:

You can copy the ID hazard: 1. ID card: Except the card number, there is no security function in the card; 2. There are many kinds of chips, such as T5577, EM4305, 5200, 5700, 8500 and 8800. 3. A treasure production market is flying all over the sky, and a few dollars can buy production equipment and access cards; 3. The landlord of the rental house is miserable and can't manage outsiders; 4. thieves are becoming more and more rampant, and so on

ID production prevention background: 1. Household access control system exists in name only, and the owners have no sense of security; 2. Rental housing management has become a social problem; 3. Property companies are at a loss, and the production of cards has become a mountain to pay property fees; 4. The system company is also very helpless; 5. Door lock reader manufacturers adopt various methods and biased means; 6. Unable to fundamentally solve the problem; 7. The incomes of hardware manufacturers, system software service providers, engineers, channel agents and property management companies have fallen sharply.

Unique performance and solution of reverse production D: 1. JH4 102 chip of Jianhe Smart Card Company; 2. Production prevention ID number (32 bits +64 bits) = password (32 bits) +ID number (64 bits); 3. The code of the conventional card reader upgrade software is to make a card reader for production prevention (note: it is not the developer of the card reader module, so it is recommended to change the reading head directly); 4. There are two options for upgrading the stand-alone/off-line access control system, namely, replacing the all-in-one card reader or updating the all-in-one program (note: it is not impossible for all-in-one manufacturers to modify it); 5. Upgrade scheme of access control system in networked community: the controller can directly replace the reader, and the system does not need to make any changes (note: the corresponding protocol is provided according to the previous reader protocol, such as WG26 protocol, which must be provided according to WG26 protocol); 6. Widely used: there are primary school parents' pick-up card system, community access control system, patrol system, and government and enterprise attendance system.
