Study of consigned designated confirmer digital signature based on elliptic curve
Haiyan Wu · Journal of Shandong University of Technology · 2007
The signature scheme based on designated confirmer was analyzed and the pitfalls on the generalization and security factors were pointed out.A signature scheme of authorized designated confirmer was established for the first time and the improved algorithm was proposed.The authenticated identifying consigner based mechanism was advanced.The protection for personal privacy was also established.At the same time,the conversion to common digital signature could be realized.The right assigned to the consigner or designated confirmer could be recalled as an optional scheme for the security and commonality problem.
