Security and efficiency improvement for image encryption algorithm based on high-dimension chaotic system
Di Xiao · Journal of Computer Applications · 2009
Concerning the high-dimension chaotic image encryption algorithm proposed by Sun et al,the authors analyzed the potential flaws and proposed corresponding improving methods in terms of security and efficiency respectively.Theoretical analysis and simulation experimental results testify that the enhancement scheme can maintain all the advantages of the original one and conquer the potential flaws.Moreover,the final scheme only needs two encryption rounds to achieve satisfactory performance.
