Problems solved by technology

[0004] Aiming at the problem that there is no suitable data encryption method for the fuze circuit, the present invention proposes a data encryption method for the fuze circuit, which adopts a simple register configuration, and the address shift data of the fuze can be stored in random order according to the settings, ensuring that the data in the data When encryption improves the safety of the fuze circuit, there will be no negative effects such as timing delay, circuit scale surge, power consumption, and volume increase caused by the encryption method being too complicated

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] Add a setting instruction of "address offset data out of order" in the setting instruction, and at the same time design a 16-bit configuration register inside the fuze circuit, and write the address shift offset and data out of order setting into the configuration register. After the configuration is completed, when valid data such as ID, timing time, and function are set, the written data will be stored in the address of "set instruction address code + address offset" in a random order according to the data out-of-sequence setting, such as figure 1 As shown; when setting the read command, the address code of the setting command should be the address after the offset, from which the out-o...

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...
