An Efficient Multi-Message Multi-Receiver Signcryption Scheme with Forward Secrecy on Elliptic Curves

Secure multicast communication has application in growing number of applications. Forward secrecy is of prime importance and insures message con…dentiality even long-term private key compromised. We present an e¢ cient construction of multi message multi receiver signcryption with forward secrecy on elliptic curves. It provides con…dentiality, integrity, authenticity, non-repudiation, public veri…ability, unforgeability and forward secrecy of multi message multicast. It is e¢ cient in computation cost and communication overhead and suitable for resource constrained IP-based secure multi message multicast systems.
