Abstract:

A distributed digital signed system based on P2P Distributed Digital Signed System (PDDSS) was proposed in this paper. This system uses peer node to compute digital signature, which replaces the CA central server. The system has many advantages: low cost, high adaptation, high availability, and intrusion-tolerance. And Verified Secret Share and Proactive Secret Share scheme are used to protect the secret key of CA.
