σ-AND Random Number Generators
Shuqin Fan · 2009
A high efficient σ-AND random number generators (RNGs) in simple structure with period 2k-1 was pre-sented,where k is the multiple of 32.Software implementation of σ-AND RNGs only requires few fundamental instructions,such as XOR,Circular Rotation,AND operations.Meanwhile due to the good pseudo randomness of their output sequences,σ-AND RNGs may be used as a primitive building block in software oriented stream cipher.
