Efficient Certificateless Signature Scheme with Provable Security
N. B. Gayathri, P. Vasudeva Reddy · 2016
Due to the limited computational resources and communicational bandwidth in wireless communication systems, Certificateless Public key Cryptography came into light and reduced a significant amount of data load on the network. Certificateless cryptographic schemes not only eliminate the certificate management complexities in the traditional Public Key Cryptography (PKC) but also resolve the key escrow problem, which is a major drawback in identity based PKC. This paper proposes a new certificateless signature scheme with formal security proof using pairings. It improves the computational and communicational efficiency along with security against the known adversaries.
