Department of Mathematical Sciences

Norwegian University of Science and Technology (NTNU) has vacancies for 3 positions at the Department of Information Security and Communication Technology (IIK) and the Department of Mathematical Sciencesat the Faculty of Information Technology and Electrical Engineering (IE). All positions are as a PhD candidate, 100% position.

The appointments are for a term of 3 years without teaching assistance, or up to 4 years including 25% teaching assistance.

Work description

Each researcher will work on a separate project in one of the following three related areas. It is expected that all researchers will collaborate and meet together regularly as a team. The project is a collaboration between members of the NTNU Applied Cryptology Laboratory.

Post-quantum primitives. Post-quantum public-key primitives are the main focus of the ongoing NIST standardization process that officially started on 30 November 2017. Initially 69 proposed schemes were proposed in three main categories: encryption schemes, key encapsulation mechanisms, and digital signatures. Those, and possibly new primitives, are the subject of the research for this position. In the next 3-4 years those primitives will be scrutinized from many different aspects such as: their security, their efficiency and practicality when implemented and used in different environments (high-end CPUs, low- power microcontrollers, FPGAs, specialized ASIC for ultra-fast and ultra-parallel or lightweight execution), how flexible, extensible and tweakable are their parameters, and how easy is their plug-in replacement with the existing and standardized public key schemes.

Post-quantum ecosystem. Current public key cryptosystems have a large associated ecosystem of auxiliary protocols and tools, such as proofs of knowledge, proofs of relations, verifiable decryption, and shuffles of ciphertexts. This ecosystem is sparse for most post-quantum schemes. Our group has already begun working on new tools, such as shuffles and verifiable decryption, mostly for lattice-based cryptosystem. We intend to continue this line of research, with a focus on lattice-based cryptography, but we will also work on code-based and multivariate cryptography.

Post-quantum key exchange. Key exchange protocols in use today typically use public key primitives and will be broken in the post-quantum world. Quantum-secure key exchange has already received some attention in the research community. However, there is a vast body of knowledge concerning key exchange, much of which needs to be re-written in the post- quantum world. This project will focus on how to achieve efficient quantum-secure key exchange which can achieve some useful key exchange properties, such as: forward secrecy, key compromise impersonation, deniability, anonymity, contributiveness, and key control. Strong models of security, such as those accounting for ephemeral key leakage and side channels, and different settings, such as password-based key exchange and group key exchange, will also be investigated.


The applicants should have a master’s degree in mathematics, computer science, communications technology or related areas. A background including experience with cryptography is desirable. Candidates completing their MSc degree in the Spring 2018 are encouraged to apply. The position is also open for integrated PhD for NTNU students starting their final year of their master degree in Autumn 2018.

The candidate must satisfy the requirements for admission to the PhD education NTNU; please see and In particular, admission to PhD education at NTNU requires an average grade of at least B, within a scale of A-E for passing grades (A best), for the last two years of the master’s degree.
