Sequential digital multi-signature scheme without using Hash and Redundancy functions
Dong Tao · Computer Engineering and Applications Journal · 2007
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.This paper points out the insecurity problem in Shi’s scheme(reference1]),and constructs a new sequential digital multi-signature scheme based on ECC.This scheme doesn’t use Hash functions or Redundancy functions and cancels the signature centre in reference 1].All the messages in the scheme will be public,signers can validate the signatures to discover fake signature and avoid the cheating by inner users.The scheme can solve the insecurity problem in reference 1],and has lower computation,higher safety,simpler structure and more applied value than Shi’s scheme.
