As known to all that Hénon chaotic system is not appropriate for generating the key-streams because it has non-uniformly distributed output signal, a new key-stream generation scheme based on Hénon chaotic system is presented.In order to get the key-streams with good statistics and long enough cycle length, a specific method for dividing the Hénon attractor into numerous non-overlapping sub-regions, and a new one-to-one mapping strategy between the divided sub-regions and elements of dynamically generated matrix consisting of 0s and ls are proposed.Experimental results demonstrate that the generated key-streams are with long enough cycle length and very sensitive to the initial values and secret keys.For example, key-streams with the cycle length of 1032 can easily be obtained.Moreover, even if the fluctuation to the initial values or secret keys is as small as 10-14, uncorrelated key-streams will be generated.Experimental results also demonstrate that the generated key-streams have good randomness and they can pass all the standard criteria specified in FIPS PUB 140-2 with no less than 98%.
