Ioannis Krontiris

PhD in IT Security with 18+ years of experience at the intersection of security architecture, data protection frameworks, and AI trustworthiness. Proven track record designing access control and authorization frameworks for agentic AI systems (OAuth-based, least-privilege, context-aware), establishing data provenance mechanisms for AI pipelines. Led large-scale EU-funded R&I programmes as technical security authority.

Active contributor to international security standardization (IETF, CEN/CLC, DIN, 5GAA). Dual capacity as hands-on security architect and strategic communicator, translating complex security requirements into verifiable system designs, actionable standards, and executive-level guidance.

Technical Manager Security R&D Europe at HUAWEI Technologies (2014-07 – 2026-03)

Technical Manager "Trustworthy AI" R&D Europe at HUAWEI Technologies (2021-07 – Present)

• Led the design and evaluation of Zero Trust and defense-in-depth security architectures for large-scale connected systems, covering the full lifecycle from threat modeling and security concept definition.
• Pioneered security architecture for agentic AI systems, designing context-aware, Least Privilege authorization protocols for AI agents based on OAuth.
• Shaped international security standards through active leadership in IETF, ETSI, CEN/CENELEC, and 5GAA (Co-Chair, WG7), translating cutting-edge research into adopted technical frameworks.

Senior Researcher "Security and Trust" at HUAWEI Technologies (2018-07 – 2021-06)

• Initiated and managed bilateral projects and led collaborations on security and trust in safety-critical systems (e.g., connected mobility, CCAM and autonomous driving), addressing challenges like reliable predictions, data integrity, and risk-aware decision pipelines.
• Advanced research on architectural resilience and trustworthy execution in distributed systems.
• Represented Huawei in pre-standardization bodies (e.g. 5GAA), contributing to trust models, credential mechanisms and safety-critical evaluation criteria.

Senior Privacy Researcher at HUAWEI Technologies (2014-07 – 2018-06)

• Designed and validated PETs supporting selective disclosure, and privacy-preserving identity flows.
• Conducted privacy and data-protection assessments for identity systems and authentication platforms; authored guidelines to ensure product compliance with GDPR, eIDAS, and internal regulatory baselines.
• Provided engineering-facing technical guidance, ensuring that IAM and identity-management components met privacy, trust, and auditability requirements.

Senior Researcher & Project Manager (PostDoc) – Security and Privacy at University of Frankfurt (2010-04 – 2014-05)

• Coordinated a €13M EU FP7 project (ABC4Trust) across 12 international partners and ~40 contributors, managing deliverables, milestones, and reporting for a complex multi-stakeholder security R&I programme
• Led the System Architecture work package, defining the unified technical architecture for privacy-preserving attribute-based credential systems
• Drove cross-functional collaboration between security engineers, cryptographers, legal experts, and policymakers to design and validate privacy-by-design credential systems deployed in real production pilots
• Translated project security outcomes into actionable guidance for EU policymakers, legal authorities, and industry stakeholders, directly influencing the direction of European digital identity standards

Postdoctoral Researcher – Privacy & Smart Environments at University of Mannheim (2008-12 – 2010-04)

• Analyzed security and privacy risks in pervasive and smart environments, focusing on threat models and protection mechanisms for distributed, resource-constrained systems.
• Evaluated security architectures for mobile and sensor-rich environments, addressing system behaviour, attack surfaces, and secure interaction models.

Research Assistant – Algorithms & Security at Athens Information Technology Institute (2005-03 – 2008-12)

Research group "Algorithms and Security"

• Designed and implemented intrusion detection mechanisms for wireless sensor networks, providing early experience with embedded security, constrained-resources systems, and real-time threat detection.
• Developed authentication mechanisms for resource-limited embedded devices, forming the foundation of later work on hardware-backed identity and secure communication architectures.
