Efficient Distributed Signcryption Scheme as Group Signcryption

The existing distributed signcryption is designed for distributing a signcrypted message to a designated group. However, it does not provide confidentiality of sender ID and its extension to a group signcryption has certain weakness. This study solves the weakness and extends to an efficient group signcryption. In addition, the proposed distributed signcryption provides with sender ID confidentiality. The extension to a group signcryption is more efficient in computational load than the existing scheme. Moreover, the group manager doesn’t need to keep and generate his group member’s secret information. It can enhance the strength of security in the protocol.
