Bit cyclic shift method to reinforce digital chaotic maps and its application in pseudorandom number generator
作者：
Highlights：
• Proposing a method that can greatly improve the dynamical degradation of digital chaotic maps.
• The improved digital chaotic map obtains high complexity without external systems introduced.
• This method has flexibility and lower implementation cost.
• This method is general for all digital chaotic maps.
• By applying the improved digital chaotic maps, a new pseudorandom number generator with good performance is designed.
