CPU card and CPU card reader
According to the need to fingerprint information stored in the IC card, by entering the user's live fingerprint card information with the fingerprint data for comparison, to achieve the true identity of the user authentication and IC card applications. Fingerprint data can be stored in a computer or network system, by entering the user's live fingerprint information with stored fingerprint information for comparison, to achieve the true identity of the user authentication, with great flexibility.
Fingerprint IC card identification technology can be widely used in network communications, database management, e-commerce and electronic payment of permissions, data access, key management. Including computer systems, Internet, e-commerce systems, government, enterprise LAN system administrator certification, and financial, insurance, securities and other industries critical systems and departments authorized staff management, stock exchanges, credit card user, the identity of beneficiaries certification and security industry applications.
Two, MF1 card and CPU card comparison:
1, non-contact logic encryption card security certification independently of each sector depends on the calibration KEYB KEYA and, by sector and KEYB control word for KEYA combination of different security, achieving sector security controls to read and write data. Non-contact logic encryption card personalization is also relatively simple, including data and various sectors KEYA, KEYB updates during all sensitive data, including KEYA and KEYB are updated directly in the form of plain text. Since the calibration KEYB KEYA and mechanisms can only solve the card-to-end authentication, but can not solve end-to-card authentication, which are commonly called "counterfeit cards," the risk.
Non-contact logic encryption card, that key is a pre-set to determine the number, no matter what method to calculate the key, and finally it must be the same number and it was originally written, it can be protected for read and write operations. So whether it is a card a secret password system or a unified system, through the crack can be achieved on non-contact logic encryption card to decrypt. Many people think that as long as the use of a card a dense, real-time online access to the system or logical encryption card ID number will be able to avoid the key being decrypted, in fact, non-contact logic encryption card is decrypted means M1 card can be copied, avoid using the online system to make illegal recharge, but can not guarantee that the illegal consumption, that is the same as copying a card ID number of the M1, it can be illegal consumption. Today's technology can be fully replicated using FPGA. Based on this principle, M1 access card is secure. Currently 80% of access control products are supported by the original IC card ID number or ID card ID number to do access control cards, no authentication or encryption to develop a dedicated key, the security risk is much lower than the cracking Mifare card more dangerous, illegal crack who just uses professional techniques to crack the process can be completed, resulting in the majority of domestic security access control products do not have one of the reasons is because the early product design theory is access from abroad over, most of domestic manufacturers continue to use abroad has long been the practice, the use of ID and IC card read-only characteristics of identification to use, very little attention to the encryption between the card and equipment certification, the lack of key system design; the ID card is easily replicable vector, resulting in almost all of the access control can easily be broken in an instant copy; this is our biggest disaster the domestic security market.
