An Efficient Authentication Protocol to amplify collision resistance using Dynamic Cryptographic Hash Function & LSB Hop based Image Steganographic Technique

摘要

This paper introduces a new authentication protocol using a different cryptographic hash function, a dynamic cryptographic hash function and a hop based Steganography. In contrast to traditional cryptographic hash functions, the dynamic cryptographic hash function needs a parameter to select the appropriate hash function dynamically. Steganography uses a hop variable to embed the secret data into an object. Using this protocol we can exchange private data securely in mobile communication over the internet.
