Our project applies Multisignature scheme for sending messages in a group.
Multisignature is more secure and eliminates the latest attacks.
Individual signers are identified by the information contained in Multisignature.
It consists of two protocols, Distributed Key Generation(DKG) and Distributed Key Regeneration/Updating(DKRU).
Java is used as the front end and MS Sql Server is used as the back end.
Existing System
In many applications , a group of members are required generate digital signature.
Individual signers remain anonymous , due to the fact that it is computationally hard to derive the individual identities from the group signature.
The computational cost for Signature generation and verification is high.
Proposed System
Individual signers do not remain anonymous , they are traceable.
This ensures accountability, i.e., a participant holds responsible for his contribution in the multisignature.
The computational cost is reduced when compared to other schemes.
We have applied the multisignature in a simple application for sending group messages
