A testing and verification device and system for encryption and decryption algorithm of identification friend or foe system

Abstract

The invention discloses an encryption and decryption algorithm testing and verification device and system for an identification friend or foe system, comprising a signal processing unit, an encryption and decryption unit and a loading management unit. The signal processing unit loads an externally input signal processing program, and the loading management unit loads the externally input encryption Decryption algorithm program and key data; the encryption and decryption unit is used to periodically generate the query signal according to the externally input query trigger signal, and encrypt to obtain the encrypted query data; the signal processing unit is used to process the encrypted query data to generate an ASK encoded signal And AM coding gate signal; Encryption and decryption unit is also used for deciphering PSV video signal to obtain response data; And the encrypted inquiry data and response data are carried out package and obtain package data; Wherein, PSV video signal is converted to response signal by outside get; the load management unit is also used to send the package data to the outside. The invention can improve the flexibility and convenience of encryption and decryption algorithm verification.

Description

technical field [0001] The invention relates to the technical field of identification of friend or foe, in particular to an encryption and decryption algorithm testing and verification device and system of an identification friend or foe system. Background technique [0002] The identification friend or foe system consists of two parts: an inquiry device and a response device. The inquiry device can transmit an inquiry signal, and the response device performs analysis and calculation after receiving the inquiry signal. After receiving the response signal, it can calculate the friend and foe attributes, location, altitude, etc. of the corresponding target. [0003] In the current military environment with increasingly fierce confrontation, modern information warfare has higher and higher requirements on the identification system of foe and foe. In order to grasp the ever-changing battlefield situation in time, the IFF system needs to quickly and accurately identify the frien...

AI Technical Summary

Problems solved by technology

When a new encryption and decryption algorithm is developed, it needs to be verified. However, the traditional identification friend or foe system is not convenient and inflexible in verification. The main reasons are as follows:

[0005] 1. Since the encryption and decryption algorithm program of the traditional identification friend or foe system is part of the signal processing program, there are many signals cross-linked with the signal processing program. Whenever a new encryption and decryption algorithm needs to be verified, the signal processing program needs to be integrated Substantial changes require a lot of time and effort;

[0006] 2. Since the traditional identification friend or foe system does not have a special data recording and analysis function, it is very inconvenient to record, compare and analyze the query data and response data when verifying the new encryption and decryption algorithm;

[0007] 3. Since the traditional identification friend or foe system only has a single program loading method, for example, it only supports JTAG interface loading, so the development of new encryption and decryption algorithms is very inconvenient

[0008] 4. Since the traditional identification friend or foe system does not have the function of program erasure, there are problems of poor security and confidentiality
