Dr. Aristidis Ilias research centers on strengthening cybersecurity within industrial, cloud, and cyber-physical ecosystems through advanced cryptographic models, secure computation frameworks, and resilient system architectures. A primary contribution lies in enhancing the security of SCADA and industrial control environments by integrating Elliptic Curve Cryptography into the Modbus protocol, enabling strong protection against interception, tampering, and denial-of-service attacks while meeting the performance constraints of real-time operational systems. Further developments address security challenges in microservice-driven data pipelines, focusing on confidentiality, authentication, and integrity in distributed architectures that support critical operations. This includes designing and validating secure communication models that leverage modern cryptographic primitives and Secure Multi-Party Computation (MPC) to ensure privacy-preserving collaborative data processing. Another important research direction advances the fusion of Linear Algebra operations with MPC, examining BLAS-level computational implementations that enable secure matrix operations at scale. These contributions include performance optimization, protocol engineering, and feasibility studies supporting the potential replacement of traditional CBLAS workflows in sensitive analytical contexts. Supported by contributions across cybersecurity projects spanning industrial protection, intelligent transportation, digital transformation, and privacy compliance, the overall research portfolio—reflected in 76 citations, 15 publications, and an h-index of 6-advances secure digital infrastructures and offers scalable, next-generation frameworks for cyber-resilient computing.
