A secure main key protecting scheme

Abstract

This paper points out the importance of protecting the main key. Because the conventional methods can do nothing about the flaws at all, this thesis puts forward the arithmetic of synthesized main key, which is based on the organic combination between the intrusion tolerance technology and the group zero-knowledge proof of the Elliptic Curve Cryptography (ECC). Through the share servers, the main key can be protected safely and validated without leaked information. Furthermore the system can work sequentially after being attacked. And this thesis strictly proves its correctness of the arithmetic by the means of the mathematics, and also reveals that this tactic effectively solves the problem of safely protecting the main key.
