Can Cao, Pengcheng Ni, Xiaohu Wang · 2021
In the past years, some encryption algorithms were designed and developed through the process of combination and permutation. Most previous algorithms independently encrypted the network components. Hence, an encryption algorithm is put forward in this paper according to a special permutation and combination algorithm. First, the new algorithm uses permutation and combination logic diagram to diffuse the relationship between network speed and network component. Next, the key stream generated by the special permutation and combination can not only modify the value of the diffusion network speed, but can also replace the network speed components spatially at the same time, connecting those three components to each other. Finally, the outcome of the modified and replaced network speed use a random cyclic shift operation for the rearrangement of the bits of every encrypted network speed and the achievement of the great complicatedness and randomness between these key streams generated, the special permutation and combination graph is independently coupled with the nearest neighboring network. The experimental outcomes display that the algorithm can be used in network security and safe communication with high security, sensitivity and speed.
