Generation of RAESSES Hash Function for Medical Blockchain Formation Based on High Dynamic Chaotic Systems.

Abstract

This paper proposes a new method of generating a high randomness hash function for the blockchain technology in healthcare industry. The hash of the block is heart of the blockchain. The integrity of the data within the block is achieved by the hash value. In medical health sector images, text, video is stored in the blockchain technology for its tampered free applications.The blockchain technology uses various standard encryption function such as MD(X), SHA family have the issues in secure data transfer becauseof fixed key generation and key dependent. To secure the images in the block, the effective chaotic RAESSES hash function was proposed based on 3D Multi scroll attractor and 3D Logistic Map based S-Box. The experimental results give the high raesses hash which fulfils the performance requirements of hash function.
