Abstract

Abstract

This paper presents a (t + 1,n)-threshold key escrow system with tolerance of t failure or withholding escrow agents on the basis of key generating of Ref.[1] and key spitting of Ref.[2], which can prevent from subliminal key attack, verify the pieces of the user s private key, effectively discover the failure or corrupted escrow agents and backup key for users. This scheme can used to real-time communication encryption and file encryption.
