Linear and Lossy Identification Schemes Derive Tightly Secure Multisignatures

Abstract

Information security is a multidisciplinary area that addresses the development and implementation of security mechanisms in order to protect information systems with specific purposes against potential attacks or threats. The security goal can be defined for each type of attacks. The currently relevant set of security goals includes confidentiality, integrity, availability, privacy, authenticity and trustworthiness, non-repudiation, accountability and auditability. However, with the rapid global penetration of network, different models are considered to design new solutions to realizing information security (e.g., in IoT or distributed scenarios). This attracts lots of attention to work on information security research on modern architecture of information systems. Very recently, the AI techniques have joined this area and also acted as a double-edged sword in realizing attacks and defenses. The main purpose of this special issue is to publish selected papers with high-quality from “15th Asia Joint Conference on Information Security (AsiaJCIS 2020).” In this special issue, we focus mainly on cryptography, network security, system security, and application security. We are interested in the novel ideas, advanced techniques, comparative analysis of different methodologies, detailed surveys, and technical reviews on all aspects of cooperative communications and mechanisms in information security. This special issue also covers industrial applications and academic research contributions, and totally includes three papers that are the extended version from their conference papers.
