Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] figure 1 For the overall structure of the present invention, serial port communication module 3, fixer interface module 4, CMG encoding module 5, control module 6, position comparison module 7 are programmed with hardware description language VHDL and are integrated in a slice of FPGA9, wherein:

[0046] Control module 6 is made up of data gating module 15, clock management module 16, FIFO module 17, display control module 18, forms the main part of password, position combination authorization-verification special chip;

[0047] One end of the setter interface module 4 is connected to the control module 6 and the CMG coding module 5 respectively, and the other end is connected to the setter 2, and the input value of the setter is converted into a recognizable coded value through the setter interface module 4 ;

[0048] One end of the CMG encoding module 5 is c...

Abstract

The invention provides an authentication method of code position combination authorization and a special chip thereof. The method conducts encoding to a code according to encoding rules of the CMG mechanism and then realizes the encoding of a group via a logical circuit so as to realize code authorization; position authorization is carried out by building an authorization central coordinate and authority radius; position authentication is carried out via the sum operation of extraction of square root and subtraction operation of an arithmetic logic unit; and after the position authentication is passed, a tri state gate is broken over, so that a state unit excites the pass of a signal, and operation of the state unit is started to carry out code authentication. The code authentication is passed by that a pin of the special chip generates a trigger signal, and authentication of an identifier combination is passed. The method is applicable to the technical field of electronic authorization.

Description

technical field [0001] The invention belongs to the field of electronic authorization control, and in particular relates to a password position combination authorization verification method and a dedicated chip thereof. Background technique [0002] Usually rights management is divided into two steps of authorization and verification. In the customs entrepot trade, there are a large number of containers and high liquidity, and its monitoring and management is challenging. Traditionally, keys, electronic passwords or other identity certificates are used for supervision, and the means are relatively single and the security is not high. [0003] 2006, 26 (6) Gao Yang's "CMG Mechanism Optimization Coding Method" article (: 106~110) of the Journal of Military Engineering disclosed a coding method for an anti-interference gear set (CMG: counter-meshing gears) mechanism. It is used in mechanical password verification mechanism, which has ingenious conception and high confidential...
