A PROVABLY SECURE MULTI-RECEIVER IDENTITY-BASED SIGNCRYPTION USING BILINEAR MAPS
Shivaramakrishnan Narayan, Udaya Parampalli · 2007
In this paper, we present a new, efficient multi-receiver identity (Id) based signcryption scheme. Our signcryption construction involves no pairing operations for sign-encrypt unlike other schemes which require at least one pairing. The scheme provides confidentiality, authenticity, non-repudiation and facilitates public verifia-bility. We provide the security result of our scheme in the random oracle model for message confidentiality and signature unforgeability properties under the multi-receiver security notion.
