A THRESHOLD KEY ESCROW SYSTEM BASED ON RSA
基于RSA的门限密钥托管方案

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.
