We propose a t-out-of-n Certificateless Threshold Ring Signature (CL-TRS) scheme and
prove its security under a new and stronger set of security models. The models capture a …

In this work a new multisecret sharing scheme for secret color images among a set of users
is proposed. The protocol allows that each participant in the scheme to share a secret color …

In cryptography, security models play important roles to define the security with potential
attacks. Following the security models, a scheme is analysed to be secure or insecure …

A (t, n) threshold signcryption scheme makes the distributor authorize a group with n
members, any t or more signcrypters can cooperatively use the signcryption keys to sign the …

Service-oriented vehicular ad hoc networks (VANETs) are expected to support the diverse
infrastructure-based commercial services, including Internet access, real-time traffic …

As an extremely significant cryptographic primitive, certificateless signature (CLS) schemes
can provide message authentication with no use of traditional digital certificates. High …

In this paper, we present the first certificateless undeniable signature scheme. The scheme
does not suffer from the key escrow problem, which is inherent in identity based …
