Provable secure identity based generalized signcryption scheme
According to actual needs, generalized signcryption scheme can flexibly work as an encryption scheme, a signature scheme or a signcryption scheme. In this paper, firstly, we give a security model for identity based generalized signcryption which is more complete than existing model. Secondly, we propose an identity based generalized signcryption scheme. Thirdly, we give the security proof of th...
متن کاملA Practical Identity-based Signcryption Scheme
In this paper, we construct a new identity-based signcryption scheme from bilinear pairings, which can process arbitrary length plaintexts. The scheme produces shorter ciphertext than the Libert-Quisquater signcryption scheme for the same plaintext and adapts to the bandwidth-constrained scenario very well. It is proved secure against adaptive chosen ciphertext and identity attack based on a va...
متن کاملProvably Secure Identity-based Aggregate Signcryption Scheme in Random Oracles
This article proposes a provably secure aggregate signcryption scheme in random oracles. Security of the scheme is based on computational infeasibility of solving Decisional Bilinear Diffie-Hellman Problem and Discrete Logarithm Problems. Confidentiality and authenticity are two fundamental security requirements of Public key Cryptography. These are achieved by encryption scheme and digital sig...
متن کاملSigncryption scheme for Identity-based Cryptosystems
An Identity-based cryptosystem is a Public Key cryptosystem in which the public keys of the entities are their identities, or strings derived from their identities. Signcryption combines digital signatures and encryption with a cost significantly smaller than that required for signature-then-encryption. This paper proposes an ID-based signcryption scheme based on bilinear pairings on elliptic c...
متن کاملEfficient and Forward-Secure Identity-Based Signcryption
Several signcryption schemes proposed in the literature are known to lack semantic security, and semantically secure signcryption schemes tend to be more computationally expensive. In fact, devising an efficient signcryption scheme providing both public verifiability and forward security was until now an open problem. In this paper, we show how a particular kind of signcryption scheme may becom...
