Problems solved by technology

[0004] There is a kind of CPU card that includes two parts of M1 and CPU in the current technology, but the two parts of this CPU card are completely independent in the internal processing flow, and there is no synchronization mechanism to synchronize the dual electronic wallets in these two parts. Therefore, when using the M1 terminal or CPU terminal for consumption, the balance of the two electronic wallets is inconsistent.

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] The present invention uses a dual-interface CPU card, which is specifically a non-contact CPU card with an ISO 14443 interface and Mifare 1 (M1 for short), such as SLE66CL80PEM, P5CD012, etc., and through the non-contact CPU Card, the present invention realizes double electronic purse application, specifically, what use the ISO 14443 interface in this contactless CPU card to realize is the electronic purse that conforms to bank standard (such as PBOC2.0 standard), namely CPU electronic purse, and uses The Mifare 1 in the non-contact CPU card implements the financial application based on the logic encryption chip standard (such as the Mifare standard), that is, the M1 electronic wallet. The two wallets are independent of each othe...

Abstract

The invention discloses a method for operating double electronic purses, relating to the information security field. The method comprises the following steps: a CPU card entering into a contactless induction zone of a terminal, electrifying and initializing the CPU card; obtaining the balance in a first electronic purse; obtaining the balance in a second electronic purse; comparing the balance in the first electronic purse and the balance in the second electronic purse; setting the balance in the second electronic purse to be identical with the balance in the first electronic purse if the balance in the first electronic purse is less than the balance in the second electronic purse; setting the balance in the first electronic purse to be identical with the balance in the second electronic purse and searching the card if the balance in the second electronic purse is less than the balance in the first electronic purse; and searching the card if the balance in the first electronic purse is equal to the balance in the second electronic purse.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for operating dual electronic wallets at a CPU terminal. Background technique [0002] The logic encryption card Mifare 1 (M1) has mature technology and low price, and occupies most of the traditional urban traffic smart card applications. However, there is no independent CPU and operating system inside the M1 card, and it completely relies on the built-in hardware logic circuit to realize security authentication and authentication. Therefore, the M1 card is easy to be cracked. According to the development trend of "one card with multiple functions and multi-card interoperability" of the transportation smart card, the fund stock of the electronic wallet in the M1 card will inevitably increase, so the security risk of M1 has caused a high degree of concern. focus on. [0003] The CPU card has a central processing unit (CPU), a random access memory (RAM), a program mem...
