Elliptic curve based multi-signature scheme for multi-server systems
Santosh Ghosh, Dipanwita Roy Chowdhury · 2008
This paper presents a multi-signature scheme based on elliptic curve cryptography. The scheme is suitable for a group of members who are connected to one of the k interconnected communicating servers. Main beauty of the scheme is that the identity of the servers are also included into the group signature. Every members and communicating servers prove their authentication to each other during signing on a message. The dynamic property of the group is also be handled very efficiently.
