Master Thesis: Time Synchronisation
Om jobbet
Join our Team
About this opportunity:
The objective of Ericsson Research Area Security is to provide Ericsson business and development units with security competence, architectures, solutions for platforms, networks, and services. Our research covers everything from pure cryptography, secure networking, AI/ML security, service layer and application security, identity management and privacy to methods for development and evaluation of security systems. Our focus is on new concepts and methods, patents, and standardization.
When joining our team at Ericsson you are empowered to learn, lead, and perform at your best, shaping the future of technology. This is a place where you're welcomed as your own perfectly unique self, and celebrated for the skills, talent, and perspective you bring to the team.
This Master Thesis project will be hosted by Ericsson Research in Kista in cooperation with Prof. Panos Papadimitratos of the Networked Systems Security group at KTH. You will be part of an international team of world-class researchers with different backgrounds, experiences, with a specialization in confidential computing and network security.
The project will focus on the security of Trusted Execution Environments (TEEs) such as Intel SGX, Arm TrustZone, or AMD SEV, that have recently gained popularity as a solution to host software services in a secure enclave on an untrusted host system. One challenge with such enclaves is to secure interactions with the untrusted host, in particular time synchronization using the NTP protocol or its NTS security extension assumes a trusted host. If the host is compromised it may interfere with time synchronization and thus subvert the security of applications that rely on an exact notion of time, e.g., for authentication or authorization. The goal of the thesis is to build a secure time synchronization service for other applications running in TEEs on a potentially compromised host.

The goal of the thesis is to build a secure time synchronization service for other applications running in TEEs on a potentially compromised host.
What you will do:
- Review papers and documentation related to TEEs, time synchronization, e.g., via NTP and NTS, and their combination.
- Study our proposed design for a secure time synchronization service.
- Implement a prototype of the service, running inside an Intel SGX enclave.
- Conduct experiments to show the security and efficiency of the proposed service and to benchmark the performance of the implementation.
- Give presentations on intermediate and final results of the work.
The skills you will bring:
- Currently pursuing a MSc degree in Electrical/Computer Engineering, Computer Science or similar.
- Strong knowledge of Linux systems.
- Programming skills in C and Python.
- A good understanding of computer security, Intel SGX, or the Network Time Protocol will be considered as a merit.
