Implementation of Certificateless Signcryption based on Elliptic Curve Using Javascript

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...

Secure Signcryption on Hyper Elliptic Curve with Sensor-Based Random Number

The emerging trend now in network security is efficient signcryption which is due to the growth of wireless technology. Signcryption scheme is proposed with security features such as confidentiality, integrity(originality of sender and receiver), message and user authentication, non-repudiation, forward secrecy and public verifiability. Signcryption fulfils the functions of signature and encryp...

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.

Cryptanalysis of an Elliptic Curve-based Signcryption Scheme

The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Although several signcryption schemes are proposed over the years, some of them are proved to have security problems. In this paper, the security of Han et al.’s signcryption scheme is analyzed, and it is proved that it has ma...
