Study on Weak Key Based on a Certain Kind of Discontinuous Chaotic Map

摘要：

With pseudo-randomicity, chaotic signals are frequently adopted in designing cryptosystem. However, it has always been ignored that there are many weak keys in chaos encryption which will bring threat to the security of the system. Taking the discontinuous piecewise linear chaotic map frequently used in chaotic cryptosystem as an example, this paper presents some weak keys which exist in this map under limited calculation precision conditions, and proves the corollary is right with numeric experiments.
