Embodiment Construction

[0034] like figure 1 As shown, the composition of the cryptographic mechanism virtual machine of the present invention includes the B register ring, which represents the actual mechanism gear set B; the A register ring, which represents the actual mechanism gear set A; and the mechanism stapler.

[0035] Based on the composition of the above cryptographic mechanism virtual machine, the following embodiments are provided in conjunction with the content of the method of the present invention, that is, the 24bit cryptographic sequence ABAABBAABBAAABABABABABBBA cryptographic mechanical solidification embodiment:

[0036] There are two examples, one is that the gear sets B and A of the cipher mechanism do not circulate, and do not have the automatic reset function of positive codes;

[0037] 1) The gear sets B and A of the cryptographic mechanism do not circulate

[0038] The total number of layers of gear sets B and A is 3

[0039] Gear set B code digit 14

[0040] Gear set A c...

Abstract

The invention relates to a cipher mechanical solidifying and checking method used for safety assurance of a high-consequence system, including the steps: 1, constructing a cipher mechanism virtual machine; 2, starting up and running the virtual machine to reduplicatively execute mechanical solidification; 3, regulating and recording ternary numerical values of registers installed on the register rings at all layers; 4, according to the ternary numerical values, completing the mechanical solidification of the cipher in layers; where the cipher is a group of A and B combinations, representing the movements of gear sets A and B, respectively. It can conveniently implement multilayer and multitooth-bit mechanical solidification of an arbitrary cipher, implement the functions of correct-code turn-on and code-error instantly locking for an arbitrary cipher, and be used in safety assurance of a high-consequence system.

Description

technical field [0001] The invention relates to a password mechanical curing method, in particular to a password mechanical curing method used for key system security assurance. The utility model belongs to the field of micro-electromechanical systems and safety insurance devices. Background technique [0002] The core technology of important system security guarantee is password mechanical solidification and identification method. Using anti-interference gear set to realize password mechanical solidification and identification is a new important system security assurance method, which has many advantages, such as simple structure; password binding logic is complex, implicit, and high security; there are few dynamic problems, and the structure of the two The dimensional and half characteristics coincide with the characteristics of LiGA or quasi-LiGA. [0003] Find through literature search, " Surface micromachined counter-meshing gears discrimination device " (surface micr...
