A High-speed Image Two-scrambling Encryption Algorithm Based on Self-generating Unit Matrix Model m
Lina Zhang · Science Technology and Engineering · 2013
A new double image scrambling encryption algorithm is presented which is based on the number theory and uses n-dimensional matrix model m as a permutation matrix.The proposed algorithm encrypts images through scrambling the space location which contains pixels and the pixels of the specific location.The implementation of this algorithm improves the security of the image encryption through expanding key space and scrambling the image histogram.At the same time the efficiency of the images encryption and decryption has been greatly enhanced.
