The Study and Design of the Website Information Survivability System Based on Hash Functions and Automatism Recovery Technology;

All the existed sequential digital multi-signature schemes use Hash and Redundancy functions,so it will take a risk of using Hash functions and Redundancy functions.

Summary of the image is generated through Hash function and the difference matrix of the carrier

Combined with the well-known scheme ECDSA,the design of the presented scheme has no time waste inverse operation through all the process,from key producing,signature calculation to verifying calculation,and use the hamming weight of Hash code of a message instead of Hash code itself to participate in the signature and verifying calculation,which can improve the computation efficiency.
