We are looking for highly motivated candidates with a strong academic track record, ideally with some background on cryptology and with proven research abilities. We offer an exciting working environment in an international network with top scientists that is geared towards cutting-edge research. The financial conditions are very attractive. The project offers an opportunity to travel and interact with other PhD students and scientists all over Europe. Candidates may have resided in the host country for a most 1 year in the 3 years preceding the application. They can have at most 2 years of research experience at the doctoral level.
In this project on Leakage Resilience from Lattices the ESR will investigate how lattice-based cryptography can be used to create leakage-resilient scheme, which will be linked to side channel resistance of various lattice-based instantiations of practical schemes. In particular, we will examine a number of unique features of lattice-based cryptography in relation to leakage. The main focus will be on developing new methods to obtain leakage-resilient schemes. A secondary focus will be on determining reasonable leakage profiles for lattice-based schemes. The project will build upon recent work on side channels and leakage-resilience, as well as lattice-based schemes, performed in Bristol, Aarhus, EPFL, ENS and across the globe. Scientifically the project will investigate the how to exploit the inherent leakiness of the underlying hardness assumptions and to what extent recent breakthroughs with regards to multi-linear maps and indistinguishability obfuscation can be brought to bear. The specific objectives are:
- To determine how additional leakage can be incorporated meaningfully in assumptions such as learning with-errors (LWE) and learning-parity with noise (LPN).
- To provide leakage-resilient lattice-based schemes, using both low-level and high-level lattice-based techniques.
The supervisory team will be Dr Elisabeth Oswald and Dr Martijn Stam for this project.
The Cryptography and Information Security Group in Bristol conduct research into cryptography, the underlying hard problems on which it is based and the hardware and software needed to implement secure systems. We form part of the Bristol Security Centre, an Academic Centre of Excellence in Cyber Security Research. The group has particular interest in techniques for proving security of cryptographic systems, the efficient implementation of such systems on small computing devices and the verification that such implementations do what they say they do. We also have an interest in security auditing and computer forensics.
ESRs will be required to formulate and execute on new research ideas and directions relevant to the grant and topic. There will be a requirement for extensive travel to visit project partners, conferences, workshops and summer schools. The post will include extended secondments to other institutions and companies across Europe. Thus all candidates must be prepared, and able, to commit to these travel requirements. The candidates will be in possession of a high ranking degree from a good university in the field of computer science, mathematics, or a related discipline. Previous understanding of modern cryptography is not essential but is desirable. The post-holders will be expected to register for a PhD at the University of Bristol (no fees will be required to register for the degree).
