Certificateless Aggregate Signatures: A Comprehensive Survey and Comparative Analysis

Abstract

This paper presents a comprehensive survey of the certificateless aggregate signature scheme in terms of their computational performance and security. This signature scheme is of significant interest because of its relevance in various domains such as Internet of Things (IoT), Vehicular Ad-hoc Networks (VANETs), E-Healthcare Medical Systems, and Mobile Healthcare Systems. Further, we point towards potential future directions for research and development in this field and conclude our study. This survey serves as a valuable resource for expanding the horizons of this scheme by envisioning new applications.
