Hi am munni i would like to get details on what is multisignature scheme for sending messages in a group ..My friend Justin said what is multisignature scheme for sending messages in a group will be available here and now i am living at nizambad and i last studied in the college nizam college and now am doing a major project i need help on multisignature scheme

The secure delivery rule ensures that any message delivered to the application by the group communication system has been received and acknowledged by all members of the group. A new multi-signature scheme that can be used in the client-server model of group communication systems to address certain problems that arise when implementing a secure delivery rule in such systems. If security is incorporated into the secure delivery rule by encrypting the acknowledgment messages from each member of the group using group key (to ensure message integrity) or requiring each member to digitally sign these messages (to prevent malicious members Interrupt the system) A message that receives these messages would have to decrypt or verify all these messages. The proposed multi-sign scheme allows the group communication server to merge acknowledgments of a message from all members of the group into a single constant-size group acknowledgment message and send it to the sender of the message. This unique recognition can be verified by any member in constant time and thus avoids the problem of performing n - 1 cryptographic operations.
