基于輕量級數(shù)字簽名的銀行卡身份認(rèn)證系統(tǒng)
[Abstract]:In recent years, although the banking card industry has been rapid development, but the risks of various bank cards are also gradually highlighted. Among them, clone bank card fraud crime showed a high trend. These criminals not only seriously affect the security of cardholders and financial institutions, but also disrupt the normal social and economic order. Therefore, it is urgent to solve the security problem of bank card, which is directly related to the development of bank card industry and the stability of financial industry. This paper first analyzes the shortcomings of the existing magnetic bank cards which are easy to be forged and the high cost of the popularization of IC bank cards, and puts forward the advantages of applying the JUNA lightweight digital signature technology and resident ID card to the anti-counterfeiting of bank cards. The customer information (including the ID number) is signed with the private key, and the generated JUNA digital identity is replaced by the CVV code stored in the track to ensure that the bank and the bank card are issued and issued, and that the bank card is not forged by the thief. And take the ID card as the secure and credible root, add the resident ID card authentication module to the existing ATM machine, ensure that the relationship between the customer and the bank card is held and be held, and ensure that even if the swiper uses the way of copying all the contents of the track to clone the card, In the absence of a card holder ID card is also unable to succeed. In ATM transaction, the bank card uses the ID number extracted from the ID card reader and the customer information stored in the track to recombine, and then use the public key to perform JUNA digital authentication of the recombined information. The result of verification ensures the corresponding relationship among customer, bank card and bank, which can prevent the bank card from stealing. Then from the point of view of customers and banks, the functional requirements of the bank card identity authentication system are put forward, and the overall framework of the system is designed, including the bank card printing subsystem, the key generation subsystem, and the key generation subsystem. The digital identity coding subsystem and the authentication and alarm subsystem can be subdivided into the authentication subsystem and the pseudo-card alarm subsystem among which the authentication and alarm subsystem can be subdivided into the authentication subsystem and the pseudo-card alarm subsystem. And the specific functions and business processes of each subsystem are designed. The key generation subsystem is used to generate the public key and the private key; the digital identity coding subsystem is used to generate the digital identity; the authentication alarm subsystem is used to verify whether the bank card is a fake card; if the verification is a fake card, the information of the corresponding counterfeit card is recorded. To provide clues for banks and the police to investigate the theft of illegal activities. Finally, the data storage method used in the system is given, the simulation realization of the system card system and the simulation realization of the ATM verification process are presented, and the security of the bank card identity authentication system based on JUNA digital signature is analyzed. By comparing with the cost of IC bank card, it is proved that the system designed in this paper has the characteristics of easy operation, low cost, high anti-counterfeiting and strong generalization.
