The Cyber Security Section at DTU Compute conducts interdisciplinary research in most aspects of computer and information security, ranging from advanced cryptography and access control mechanisms, for ensuring secrecy and authentication in todays’ communications, to the design, analysis and implementation of novel protection mechanisms for enhanced security, privacy, trustworthiness, and reliability in numerous emerging IoT applications. Through methods such as applied cryptography, hardware enhanced security, modelling and security analysis of systems, and verification, we are building security into new technology, providing assurance to the user that they are interacting with a trusted platform. Our research focuses on cryptography; trusted computing; secure communications; privacy and authentication; and security verification – with applications in, e.g., automotive, future Internet and 5G, smart grid, healthcare, e Payment, etc.

This PhD scholarship is funded by the RAINBOW research project as part of the European Union H2020 programme. The goal of RAINBOW is to design and develop an open and trusted fog computing platform that facilitates the management of scalable, heterogeneous and secure IoT services and cross-cloud applications. With the rise of Internet of Things and fog computing, the number of devices that run potentially vulnerable software has exploded, and vulnerabilities are increasingly being discovered in the software running on these devices. To keep up with the amount of services that must be vetted for vulnerabilities, an automated approach is required. Alternative, security architectures are required which allow the system to detect whether it is under attack, and therefore intensify the protection mechanisms. Particular focus would be given on control systems, communication and computing infrastructures, wireless communication and embedded software verification. The envisioned research activities include the design and development of cryptographically secure and scalable attestation mechanisms for enhancing the overall privacy posture of deployed fog devices as well as verifying the integrity of deployed software-based services.  Furthermore, carrying out research towards the vulnerability analysis of the leveraged Trusted Platform technologies (i.e., TPMs) and the underlying TCG Software Stack (TSS) as well as the market landscapes to allow a detailed design phase to proceed.

Examples of specific research aspects to be investigated include:
 

  • Definition and investigation of hybrid layered attestation approaches for enabling the collective attestation of edge devices. This will include the design of advanced attestation enablers such as Direct Anonymous Attestation (DAA) and control- and information-flow attestation;
  • Modelling of appropriate verification mechanisms needed for protecting the remote attestation mechanisms and edge services from unauthorized access;
  • Design and implementation of efficient and scalable (aggregate) remote attestation for a multitude of potentially heterogeneous edge devices and services;
  • The modelling of a trusted mesh overlay network that can be deployed over geo-distributed resources and can manage the trusted exchange of data and services
The objective of this project is to engage trusted and fog computing technologies towards developing a unified security overlay mesh network for enabling the secure and trustworthy orchestration and data management of emerging IoT-based edge applications and services.

Responsibilities and tasks
The primary task of the PhD candidate will be to conduct original research in the area described above with the goal to produce a PhD dissertation by the end of the 3-year program.

The goal is to answer difficult questions concerning the integration of advanced remote attestation enablers in the context of fog computing and the design of sufficient privacy-preserving protocols based on the use of trusted computing. The research outcomes will expected to be applied in security, privacy, trust and operational assurance of IoT-enabled ecosystems.

The PhD candidate will learn to write articles reporting the original results, of a sufficient high quality to appear in top scientific conferences and journals. He/she will participate in relevant conferences in the relevant field and, as part of the PhD program; he/she may have the opportunity for an external research stay abroad of 3-6 months.

It is a requirement of the program that all PhD students take advanced courses amounting to approximate 30 ECTS points. As part of the salary, there is a requirement of performing additional tasks (about 3 months during the 3 years) in the area of teaching or other departmental work.

Qualifications
Candidates should have a two-year Master’s degree or a similar degree with an academic level equivalent to a two-year MSc degree. A good background in the theory and practice of system and network security is essential, and preference will be given to candidates who can demonstrate knowledge on trusted computing concepts, fog computing, applied crypto and trust management. Good implementation skills and practical experience are also desirable. Furthermore, good command of the English language is essential.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU PhD Guide.
