Recent Advances in Security, Privacy, and Trust, 2nd Edition

Dear Colleagues,

We are pleased to announce the second edition of our previous and successful Topic “Recent Advances in Security, Privacy, and Trust”.

The proliferation of information, communication, and computer technologies has brought us into the realm of the cyber–physical–social system (CPSS). The CPSS comprises cyber space, physical space, and social space, and their integration into such systems as cyber-physical systems (CPSs), the Internet of Things (IoT), social media, and even a system that integrates all three spaces. Recently, the CPSS has brought enormous opportunities that have significantly influenced how technologies are implemented; however, there are increasing security, privacy, and trust concerns, such as the exposure of user privacy and business information in the CPSS. Although theories and technologies regarding security, privacy, and trust have been widely studied and applied in recent years, existing methods remain insecure, impractical, or inefficient. To address these challenges, this Topic solicits articles reflecting the latest research outcomes and developments in security, privacy, and trust.

In light of growing concerns over the sustainability of technological ecosystems, this Topic seeks to explore the sustainable development of security, privacy, and trust frameworks, emphasizing environmentally friendly approaches, resource efficiency, and the long-term viability of security technologies—submissions of research that addresses these challenges while reflecting the latest innovations in ensuring sustainable and resilient systems across various domains are particularly encouraged. Areas of interest include, but are not limited to, the following topics:

• Privacy-enhancing technologies;
• Privacy-preserving/secure/trust data analysis and processing;
• Network security, privacy, and trust;
• Differentially private data analysis;
• Sustainable security, privacy, and trust;
• Economics of security, privacy, and trust;
• Blockchain and its applications;
• IoT/CPS/CPSS security, privacy, and trust;
• Security, privacy, and trust in edge/fog/cloud computing;
• AI/Machine learning security;
• Federated learning;
• System security;
• Hardware security;
• Web security, privacy, and trust;
• Big data, artificial intelligence for security, privacy, and trust;
• Digital twin security, privacy, and trust;
• Cryptographic techniques, cryptographic protocols.
