An efficient multi-receiver certificate less digital multisignature scheme with anonymity

Abstract

Certificate-less (CL) signature schemes were presented to deal with key escrow issue in ID based signature. In recent years a number of digital signatures schemes with bilinear pairing have been presented to maintain information security and integrity. Acutely, the greater part of them endure intent security invasion. They don’t enforce in terms of computing and dissemination complications. Many researchers have proposed different schemes on anonymity for multi receiver identity based cryptography. In this paper an attempt has been made to propose an efficient CL Digital Multi-Receiver (CL-DMS) scheme with anonymity without bilinear pairing which is secure against foregeability, key replacement and key escrow attack. Our motivation is to design a CL DMS that simulcast a message with high level of computation efficiency and employs security that only proficient recipients can fetch the message. This will also include the non-repudiation as well as the time replay attack. We presented an enhanced and efficient scheme, which is secure against Type 1, and Type II attacks. We also compare the proposed scheme with some existing schemes in terms of computation and communication cost with higher level of security.
