Certificateless Elliptic Curve Aggregate Signcryption Scheme

Certificateless 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...

Efficient Certificateless Signcryption Scheme

In this paper, we propose a certificateless signcryption scheme from Weil pairings and give a practical security model. Compared with existing schemes, the new scheme is more efficient.

ECGSC: Elliptic Curve based Generalized Signcryption Scheme

Signcryption is a new cryptographic primitive that simultaneously fulfills both the functions of signature and encryption. The definition of generalized signcryption is proposed in the paper firstly. Generalized signcryption has a special feature that provides confidentiality or authenticity separately under the condition of specific inputs. So it is more useful than common ones. Based on ECDSA...

An 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 ...
