A new algorithm of encryption in non-cooperation IFF system

The technology of identification of friend or foe(IFF) has been extensively applied in the information warfare with the development of science and technology. The Algorithm of dynamic encryption based on current date as seed, two times operation to the seed by two groups of keys, is put in Non-Cooperation IFF system in this paper, which data quantity is smaller and security, reliability, confidentiality also could meet the need of requirement, so it fit high dynamic and high mobility weapon system.
