Certificateless aggregate signcryption: Security model and a concrete construction secure in the random oracle model
Certificateless cryptography; Aggregate signcryption; Random oracle model; Bilinear pairing Abstract The concept of aggregate signcryption was first introduced in 2009 by Selvi et al. [Identity based aggregate signcryption schemes, Lecture Notes in Computer Science 5922 LNCS, 2009, pp. 378–397]. The aggregation process of these schemes reduces the amount of exchanged information and is particul...
متن کاملCertificateless Aggregate Signcryption Schemes
The concept of an aggregate signcryption scheme was first introduced in 2009 by Selvi S.S.D. et. al. in the identity-based setting. The aggregation process of these schemes reduces the amount of exchanged information and is particularly useful in low-bandwidth communication networks and computationally-restricted environments. In this paper, we define a suitable security model for certificatele...
متن کاملAn efficient certificateless signcryption scheme in the standard model
Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...
متن کاملA Strongly Secure Certificateless Digital Signature Scheme in the Random Oracle Model
The main purpose of this paper is to provide a security proof for the certificateless digital signature scheme found in [Hassouna, Bashier, and Barry, A short certificateless digital signature scheme, International Conference of Digital Information Processing, Data Mining and Wireless Communications, 2015, pp. 120–127] in the random oracle model. Two types of attacks are considered: The first t...
