The Development of the Technology of Digital Signature on Solving Key Exposure Problem
Ying Wang · Microprocessors · 2006
The damage of key-exposure has become the focus of the research.This problem may hardly be resolved complementally,what we can do is to minimizing the damage as we can.Many different approaches have been proposed and implemented to tackle this problem.In this article we introduce some of them and figure out the strength and the shortcoming of them.In SiBIR signature scheme,due to network congestion or active attack from an adversary, a single refresh message will be lost which makes signer and home base losing synchronization.To counter this problem we propose a timeout synchronization scheme.
