Abstract |
|
|
| Security of the image information has become more and more important. At present,
researchers have paid much attention to DNA cryptography-based image encryption.
In this paper, an efficient encryption approach is proposed, in which, we do not use
DNA biological operation to implement image encryption, but DNA sequences are
used as the secret keys. The permutation process is implemented by using Hao’s fractal
sequence representation and the diffusion process is used to alter the gray values.
According to the simulation experiment and performance analysis, this approach is
feasible and effective. |
