Certificate-Based Signcryption: Security Model and Efficient Construction
Signcryption is an important cryptographic primitive that simultaneously achieves confidentiality and authentication in an efficient manner. In 2008, Luo et al. introduced the notion of certificate-based signcryption and proposed the first construction of certificate-based signcryption. However, their scheme is insecure under the key replacement attack and also does not provide insider security...
متن کاملCertificate-Based Secure Three-Party Signcryption Scheme with Low Costs
A signcryption scheme combining public key encryption and digital signatures can simultaneously satisfy the security requirements of confidentiality, integrity, authenticity and non-repudiation. In a three-party communication environment, a message signcrypted by one party might have to be securely delivered to the other two and they usually independently decrypt the ciphertext and verify recov...
متن کاملEfficient Certificate-Based Signcryption Secure against Public Key Replacement Attacks and Insider Attacks
Signcryption is a useful cryptographic primitive that achieves confidentiality and authentication in an efficient manner. As an extension of signcryption in certificate-based cryptography, certificate-based signcryption preserves the merits of certificate-based cryptography and signcryption simultaneously. In this paper, we present an improved security model of certificate-based signcryption th...
متن کاملID based generalized signcryption
Generalized signcryption is a new cryptographic primitive in which a signcryption scheme can work as an encryption scheme as well as a signature scheme. This paper presents an identity based generalized signcryption scheme based on bilinear pairing and discusses its security for message confidentiality non repudiation and ciphertext authentication.
متن کاملIdentity-Based Signcryption
A signcryption scheme is a scheme that provides private and authenticated delivery of messages between two parties. It does this in a more eecient manner than a straightforward composition of an encryp-tion scheme with a signature scheme. An identity-based cryptosystem is one in which the public key may be any string (or may be derived from any string). In this paper we propose an identity-base...
