Identity-Based Signcryption
نویسنده
چکیده
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-based signcryption scheme. We give a security model for such a scheme and sketch the details of how our scheme may be proved secure in this model.

Identity based signcryption scheme without random oracles
Signcryption is a cryptographic primitive which performs encryption and signature in a single logical step with the cost lower than signature-then-encryption approach.. In this paper we gave attacks on confidentiality and unforgeability of two identity based signcryption schemes without random oracles. Further we proposed an improved identity based signcryption scheme without random oracles. We...
متن کاملGeneralized Hierarchical Identity-Based Signcryption
In this paper, we propose a generic method to construct Hierarchical Identity-Based Signcryption scheme. Using this method, a Hierarchical Identity-Based Signcryption scheme can be converted from any Hierarchical Identity-Based Encryption scheme. Then, we give a concrete instantiation, which is the first constant-size fully secure hierarchical identity-based signcryption scheme in the standard ...
متن کاملCryptanalysis of an Identity Based Signcryption Scheme without Random Oracles
Signcryption is a cryptographic primitive that aims at providing confidentiality and the sender’s identity authentication in a logic step, at lower computational costs and communication overheads than sign-then-encrypt way. Recently, Yu et al.[1] proposed a new identity based signcryption scheme in standard model. However, in this paper, we show that the scheme still has some security weaknesse...
متن کاملProvable 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 کاملOn the Security of ID Based Signcryption Schemes
A signcryption scheme is secure only if it satisfies both the confidentiality and the unforgeability properties. All the ID based signcryption schemes presented in the standard model till now do not have either the confidentiality or the unforgeability or both of these properties. Cryptanalysis of some of the schemes have been proposed already. In this work, we present the security attack on ‘S...
متن کاملIdentity Based Public Verifiable Signcryption Scheme
Signcryption as a single cryptographic primitive offers both confidentiality and authentication simultaneously. Generally in signcryption schemes, the message is hidden and thus the validity of the ciphertext can be verified only after unsigncrypting the ciphertext. Thus, a third party will not be able to verify whether the ciphertext is valid or not. Signcryption schemes that allow any user to...
