Pairing-free Proxy Signature based on ECDLP

This book contributes to the variants of proxy signature scheme based on ECDLP without pairing. Significance of the scheme in chapters is not only to provide a secure and improved signature protocol but to enhance the efficiency of the scheme in the sense of computational operation-time with compare to the other available ID-based proxy signature schemes from pairings. These schemes do not use pairings still provid signatures in ID based settings. I believe that these signature schemes with formal security model without bilinear pairings will be helpful to bring a breakthrough towards the improvement of efficiency and security proofs of such schemes. I also believe that this work will be helpful for new researchers to enhance their interest in this field and to extend the related research in future with a vast list of references.
