Problems solved by technology

However, for the most critical security part of the specification, the PBOC2.0 specification is equivalent to adopting the corresponding content in the EMV2000 standard, including the selection of cryptographic algorithms and secure transaction protocols, etc. The cryptographic algorithms are all foreign cryptographic algorithms, and the financial cards basically use foreign chips. , leaving a great security risk
The security of the above-mentioned foreign cryptographic algorithms has not been fully tested by domestic cryptographic experts and relevant departments. Some international experts have questioned the security of these algorithms. Some algorithms, such as the 1024-bit RSA algorithm, have been cracked in practical applications.
The security chip is the main carrier of the cryptographic algorithm. Foreign chip manufacturers may install a "back door" in the security chip. The "back door" can be activated by special means, and the various data processed by the chip can be sent back, and the chip can also lose its work. ability

Embodiment 1

[0025] A schematic structural diagram of a complex financial transaction system provided in this embodiment is as follows: figure 1 As shown, the following units are included:

[0026] Financial cards, financial terminals, compound financial PSAM cards and bank background. The specific functions of each unit are introduced as follows:

[0027] Financial card, which can be one: composite financial electronic wallet / electronic passbook card, composite financial debit card / credit card or composite financial IC card, supports two sets of cryptographic algorithm systems: domestic cryptographic algorithm system and foreign cryptographic algorithm system. It is used to negotiate with the financial terminal to determine the use of foreign cryptographic algorithms and / or domestic cryptographic algorithms to store the user's financial information, which includes the user's private key and related digital certificate information for online banking. The cryptographic algorithm completes...

Embodiment 2

[0036] When the above-mentioned financial card is a compound financial electronic wallet / electronic passbook card, when the financial terminal completes the electronic wallet / electronic passbook consumption business, the financial terminal uses the PSAM card to calculate MAC1 and returns the value of MAC1 and the terminal offline transaction number to the financial terminal , and then the financial terminal sends a consumption command to the composite financial electronic wallet / electronic passbook card, and the composite financial electronic wallet / electronic passbook card returns MAC2 and TAC2 to the financial terminal, and then the financial terminal uses the PSAM card to verify MAC2, and returns the information through the PSAM card Verify the results, and complete the electronic wallet / electronic passbook consumption business of the complex financial electronic wallet / electronic passbook card.

Abstract

An embodiment of the invention provides a composited financial transaction method and system. The composited financial transaction system supports an application of ATM (Automatic Teller Machine) cards of a foreign cryptographic algorithm system and a domestic cryptographic algorithm system. The application of the composited financial transaction system has the advantages of promoting the application of the domestic cryptographic algorithm in the financial payment field, strengthening ATM card safety and controllability in the financial payment field, maintaining compatibility of financial terminals which do not support the existing domestic cryptographic algorithm during the popularization process of the domestic cryptographic algorithm ATM cards and well promoting the application of the domestic cryptographic algorithm in the financial payment field.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of financial transactions, and in particular, to a compound financial transaction method and system. Background technique [0002] Drawing on foreign EMV2000 standards, the People's Bank of China promulgated the "China Financial Integrated Circuit (IC) Card Specifications (2005)" (hereinafter referred to as: PBOC2.0 Specifications) in 2005. In 2010, the PBOC2.0 specification was revised and the "China Financial Integrated Circuit (IC) Card Specification (2010)" was promulgated, which is the latest version of the PBOC2.0 specification. [0003] On March 15, 2011, the People's Bank of China issued the "Opinions of the People's Bank of China on Promoting the Application of Financial IC (Integrated Circuit) Cards" (hereinafter referred to as "Opinions"), and decided to officially launch bank card chips nationwide. Migration work, during the "Twelfth Five-Year Plan" period will comprehe...
