University of Surrey, Surrey Centre for Cyber Security, UK
Job PostingDisclaimer: This position is funded by HM Government and is available only to UK citizens.
Surrey Centre for Cyber Security (SCCS) at the University of Surrey invites applications for a fully-funded PhD position in Cryptography to work on a research project focusing on the design, analysis and development of multi-factor authentication protocols.
The successful candidate will be working under supervision of Dr Mark Manulis (Principal Supervisor, http://www.manulis.eu) and Dr Thanassis Giannetsos (Co-Supervisor).
Successful applicants are expected to hold Bachelor degree or Master degree in Information Security, Computer Science, Mathematics or related discipline accomplished with at least 2:1 honours and have strong background knowledge and technical skills (incl. programming skills) in cryptography and/or information/cyber security. A related research-oriented BSc final year project or MSc dissertation will strengthen the profile of the candidate. We particularly welcome applications from ongoing students who are projected to fulfil the above criteria and complete their degree in 2018.
The appointed candidate will receive a tax-free PhD stipend of GBP 22,000 per year for 3.5 years of PhD studies within which the candidate is expected to submit their PhD thesis. This stipend is significantly higher than an average PhD stipend in the UK. Additional funding is available to support presentation of research results at international conferences, participation in PhD summer schools and other scientific events, and engagement with industry.
Prior to submitting your application please contact us by email.
Closing date for applications: 31 March 2018

ePrint ReportWe design a synchronized aggregate signature scheme that works for a bounded number of periods $T$ that is given as a parameter to a global system setup. The big technical question is whether we can create solutions that will perform well with the large $T$ values that we might use in practice. For instance, if one wanted signing keys to last up to ten years and be able to issue signatures every second, then we would need to support a period bound of upwards of $2^{28}$.
We build our solution in stages where we start with an initial solution that establishes feasibility, but has an impractically large signing time where the number of exponentiations and prime searches grows linearly with $T$. We prove this scheme secure in the standard model under the RSA assumption with respect to honestly-generated keys. We then provide a tradeoff method where one can tradeoff the time to create signatures with the space required to store private keys. One point in the tradeoff is where each scales with $\sqrt{T}$.
Finally, we reach our main innovation which is a scheme where both the signing time and storage scale with $\lg{T}$ which allows for us to keep both computation and storage costs modest even for large values of $T$. Conveniently, our final scheme uses the same verification algorithm, and has the same distribution of public keys and signatures as the first scheme. Thus we are able to recycle the existing security proof for the new scheme.
We also show how to extend our results to the identity-based setting in the random oracle model, which can further reduce the overall cryptographic overhead. We conclude with a detailed evaluation of the signing time and storage requirements for various practical settings of the system parameters.

ePrint ReportIn this work we consider a progressive approach to lattice sieving, where we gradually introduce new basis vectors only when the sieve has stabilized on the previous basis vectors. This leads to improved (heuristic) guarantees on finding approximate shortest vectors, a bigger practical impact of the quality of the basis on the run-time, better memory management, a smoother and more predictable behavior of the algorithm, and significantly faster convergence - compared to traditional approaches, we save between a factor $20$ to $40$ in the time complexity for SVP.
