Scheme of Electronic Seal Based on Public Key Infrastructure

This paper improves the general electronic seal scheme based on PKI platform. The original scheme has low efficiency and complicated process when seal's authenticity is verified. In this new scheme, before the seal is used for the time a random code will be created by CA. The random code and the electronic seal image will be printed together. User can easily complete the seal security anti-counterfeiting verification under security strength with no high requirement, through contacting CA for checking the random.
