A Distributed CA-Key Generation Scheme for Resilience CA

Resilience CA is a CA system which implements an intrusion tolerant algorithm to protect the private key of CA. It enhances the security of system by implementing a new method to split the private key, but it uses a key distribution center to generate the CA-key and this center compromises the private key. Based on the traditional resilence CA scheme, this scheme cancels the key distribution center, and implements a distributed algorithm to generate a shared CA key, so that any t-1(t is the threshold number) servers can't compromise the private key of CA in the initialization and running stage of CA.
