Journal ArticleDOI
A novel chaos-based image encryption using DNA sequence operation and Secure Hash Algorithm SHA-2
TL;DR: The theoretical analysis and experimental results show that the algorithm improves the encoding efficiency, enhances the security of the ciphertext and has a large key space and a high key sensitivity, and it is able to resist against the statistical and exhaustive attacks.
Journal ArticleDOI

TL;DR: The promising results of the proposed sleep staging framework suggest that it may be a valuable alternative to existing automatic methods and that it could accelerate visual scoring by providing a robust starting hypnogram that can be further fine-tuned by expert inspection.
Journal ArticleDOI
A novel chaos based optical image encryption using fractional Fourier transform and DNA sequence operation
TL;DR: A new method for optical image encryption using fractional Fourier transform, DNA sequence operation and chaos theory is proposed, which has good encryption effect, larger secret key space and high sensitivity to the secret key.
Journal ArticleDOI
Hash key-based image encryption using crossover operator and chaos
TL;DR: Experimental results and security analysis show that the scheme can achieve good encryption result through only one round encryption process, the key space is large enough to resist against common attacks, so the scheme is reliable to be applied in image encryption and secure communication.
Journal ArticleDOI
A New Approach for Clustering in Wireless Sensors Networks Based on LEACH
TL;DR: In this article, a new method is proposed to optimize Low Energy Adaptive Clustering Hierarchy (O- LEACH) to improve existing LEACH and LEACH-C by selecting cluster according to the residual energy of nodes dynamically.
