Special Issue Information

Dear Colleagues,

Symmetry is an extraordinary characteristic which has been widely deployed in different research fields of computer engineering, such as symmetric architecture for telecommunications, symmetric network structures, and symmetric algorithms. Recently, an increasing number of organizations have embraced zero-trust technologies due to their ability to minimize risk in enforcing accurate, least privilege per-request access decisions in service applications under the circumstance of a compromised network. In a zero-trust architecture, each access request should be authenticated and evaluated whether the request is permitted no matter whether it originated from an external or internal network. In addition, unauthorized people from utilizing devices of authorized users can intrude other devices for lateral movement. Organizations need to evaluate the trustworthiness of access requests based on user behaviors and threat intelligence and adapt their associated access control policies. To date, the research community has stressed the importance of innovative technologies and integrated solutions for zero-trust. Therefore, this Special Issue solicits original and high-quality works, involving the concept of symmetry, on recent advances in innovative technologies, challenges, and solutions for zero-trust. Topics of interest include, but are not limited to:

  • Trust evaluation algorithm with symmetry for zero-trust;
  • Cyber threat intelligence with symmetry for zero-trust;
  • Edge device risk evaluation with symmetry for zero-trust;
  • Emerging innovative access control with symmetry for zero-trust;
  • Novel theories, architectures, applications, and paradigms with symmetry for zero-trust;
  • Security modeling with symmetry for zero-trust architecture;
  • Privacy enhanced technologies with symmetry for zero-trust;
  • Effectiveness evaluation and benchmark with symmetry for zero-trust;
  • Advances in the use of zero-trust underlying technologies (e.g., AI, blockchain, deterministic networks, cloud/edge computing, etc.) with symmetry;
  • Miscellaneous issues with symmetry for zero-trust.

The large and interconnected nature of the Internet of Things (IoT) presents unique security challenges, even as it revolutionizes various sectors. With numerous devices, often limited in resources, traditional perimeter-based security methods struggle to keep pace. The “never trust, always verify” principle of zero trust security offers a viable solution. Zero trust security is a concept that has become increasingly popular, using key exchange techniques to ensure secure and authenticated communication within the network, especially in managing risks in critical infrastructure. Authentication is a process to identify an entity, a prerequisite for authorization, and essential for granting access control. It fundamentally relies on trust management and various methods to generate and manage cryptographic keys for authentication. The aim of this study is to enhance zero trust security in the context of the Internet of Things by investigating authentication methods and discussing several potential solutions for successful implementation. This study also presents the performance evaluation criteria for authentication in IoT and introduces advanced approaches for different scenarios, including lightweight cryptography, mutual authentication, and blockchain technology. Finally, we address challenges related to implementation and future directions for research. Full article
