A fuze circuit address shift data out-of-sequence encryption method

Abstract

The invention discloses a disorder encryption method of fuze circuit address shifting data. A address shifting data disorder setting instruction is added in a setting instruction, meanwhile, a 16-bot configuration register is arranged in a fuze circuit, and an address shifting offset and a data disorder setting are written into the configuration register; when effective data including ID (Identity), timing time and functions are set, written data is stored in an address of a setting instruction address code+address offset in an order disruption way according to the data disorder setting; and when the fuze circuit works, the effective data, including ID (Identity), timing time and functions, is read to carry out work judgment, disordered data is read from a deviated address according to the address shifting offset and the data disorder setting set in the configuration register to carry out decoding, and the fuze circuit beings to work after correct data is obtained. The fuze circuit is encrypted through the disorder encryption method of the address shifting data, the safety of the fuze circuit is improved, and the scale of the circuit is not enlarged.

Description

technical field [0001] The invention relates to a fuze circuit address shift data out-of-order encryption method, which belongs to the technical field of data encryption in semiconductor integrated circuits. Background technique [0002] Before the fuze circuit works, various data such as ID, timing time and function need to be pre-installed. At present, there is no data encryption method specifically for the fuze circuit, and the set data is easy to be cracked. There are many other types of data encryption algorithms, but the algorithms are too complex and difficult to realize through semiconductor integrated circuits. Moreover, an overly complex encryption algorithm is not conducive to the miniaturization, lightweight and modularization of the fuze system structure, and cannot conform to the development direction of modern weapon systems. [0003] At present, there is no data encryption patent design specifically for fuzes. The paper "Research on the Application of an En...
