The new symmet ric block cipher SWING which we put forward here is wholly performed by the state change of a shift register.We give the detailed encryption and decryption schemes and setting s of some necessary parameters.By the cryptanalysis of key bit avalanche effect and plaintext bit avalanche effect, we show that SWING has remarkable properties on defending of some usual ways of cry ptanaly sis and attacks, such as linear and differential cry ptanalysis, and related keys.Besides security, easy implementation and high speed of encryption and decryption, SWING has as well the feature of precision and simple structure which serves efficient confusion and diffusion.
