Cooperative Laser IFF Technology Based on Encryption Mode
In order to solve the problem that the signal is easily detected and deciphered in general laser Identification,Friend or Foe(IFF),a cooperative laser IFF technology based on encryption mode is proposed.The working principle of laser IFF system is studied and analyzed.The time information is used to generate a set of pseudo-random numbers.A set of high-strength improved en-cryption algorithm is used to transform the pseudo-random numbers to generate encrypted data,and the encrypted data is spread by the spread-spectrum function.Combined with the Reed-Solomon(RS)error correction code,the final code is generated to enhance the anti-jamming ability of the data.Experimental results show that the signal confidentiality and security are enhanced,and it provides a new idea for the laser IFF development.
