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