An ideal multi-secret sharing scheme based on minimal privileged coalitions [PDF]
, 2012 How to construct an ideal multi-secret sharing scheme for general access structures is difficult. In this paper, we solve an open problem proposed by Spiez et al.recently [Finite Fields and Their Application, 2011(17) 329-342], namely to design an ...

A Provably-Secure Outsourced Revocable Certificateless Signature Scheme Without Bilinear Pairings
IEEE Access, 2018 Certificateless public key cryptosystem (CLPKC) is a desirable cryptographic system because it refrains from both certificate management and key escrow. In CLPKC, how to revoke a misbehaving or compromised user is an important issue.

A secure Certificateless Aggregate Signature Scheme
International Journal of Security and Its Applications, 2016 Aggregate signatures allow n signatures on n distinct messages from n distinct signers to be aggregated into a single signature that convinces any verifier that n signers do indeed sign the n messages, respectively. The major advantage of utilizing aggregate signatures is to address the security of data and save bandwidth and computations in sensor ...

On the security models for certificateless signature schemes achieving level 3 security [PDF]
, 2011 Public key cryptography has found many applications in our modern society. To guarantee the authenticity of public keys, we need a trusted third party (TTP). In 1991, Girault defined three trust levels for a TTP.

New Certificateless Blind Ring Signature Scheme
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2014 A new certificateless blind ring signature scheme was proposed in this paper. The scheme could not only avoid the problem of certificate management of public key certificate cryptography, but also overcome the inherent key-escrow problem of identity-based public key cryptography. In the last, by using bilinear pairing technique, it was proved that this
