Certificateless Group Oriented Signature Secure Against Key Replacement Attack
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificate...

Group-oriented Encryption Secure against Collude Attack
A group oriented encryption scheme is presented in this paper. In this scheme, a sender is allowed to encrypt a message using the group public key and send the ciphertext to the gr...

On the relation among various security models for certificateless cryptography
: Certificateless cryptography is a promising technology for solving the key escrow problem in identity-based cryptography. However, the lack of a unified set of definitions and se...

Distributed Key Management with Protection Against RSU Compromise in Group Signature Based VANETs
—The group signature based security scheme is a promising approach to provision privacy in vehicular ad hoc networks (VANETs). In this paper, we propose a novel distributed key m...

Machine-Checked Security Proofs of Cryptographic Signature Schemes
Abstract. Formal methods have been extensively applied to the certification of cryptographic protocols. However, most of these works make the perfect cryptography assumption, i.e....
