Embodiment Construction

[0029] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0030] In order to solve the problems of high command distribution time overhead and poor security in the prior art, the present invention proposes a method and system for command distribution of an intelligent security chip based on inversion technology.

[0031] When the smart security chip communicates with the terminal device, information is exchanged through the APDU command. When the command enters the smart security chip, the command is first distributed to the function mode of the corresponding application through the command distributor to complete the parsing and execution of the command and return. That is, after receiving the instruction, determine the corresponding instruction record according to the instru...

Abstract

The invention discloses an inversion technology-based instruction distribution method and system for intelligent security chips. The method comprises the following steps: establishing instruction records which comprises the basic information required by instruction distribution; distributing a corresponding unique offset address for the instruction record of each chip type according to different chip types; establishing an instruction inversion table which comprises instruction words and the unique offset addresses, wherein each instruction word corresponds to a plurality of unique offset addresses and the number of the unique offset addresses is same as the number of the chip types; receiving an instruction from terminal equipment and determining a corresponding instruction record according to the instruction word and chip type of the instruction; judging whether a data domain of the instruction needs to be received according to an instruction data domain sign of the instruction and the corresponding instruction record; if the judging result is positive, receiving the data domain of the instruction; and of the judging result is negative, skipping the step.

Description

technical field [0001] The present invention relates to the technical field of command distribution in the communication field, and in particular, to a method and system for command distribution of an intelligent security chip based on inversion technology. Background technique [0002] Before the smart security chip was used on a large scale, the products that were widely used in related fields mainly included memory cards with various interfaces, interface chips, and magnetic stripe cards. These products do not have the ability to identify visitors, the stored data is not safe, and it is easy to be forged and copied. Visitors can directly read the data inside through an open protocol. [0003] After the rise of the smart security chip industry, traditional products have gradually been replaced. At present, smart security chips are widely used in telecommunications, banking, electric power and other fields for safe storage of data, identification, and security control. The...
