Distributed signcryption is specifically designed for distributing a signcrypted message to a designated group. As such, it can not be used in anonymous communication. Accordingly, the current study adds an anonymity property to distributed signcryption that results in almost the same computational load as regards the modular arithmetic. Therefore, the new scheme is more efficient than the expansion for anonymity in, and has potential applications in electronic commerce.
