Funded Doctoral Studentship in Applied Cryptography for UK applicants – annual stipend £23,000

Posted: 22nd October 2013

Supervisors: Dr Cas Cremers and Dr Andrew Simpson

Start Date: October 2014 End Date: April 2018


We are looking for a top student in computer science or mathematics for a project on improving the security of network communications. The project focusses on the so-called key exchange phase that forms a core building block for establishing secure channels. Our goal is to use cryptographic techniques and proof methods to provide new forms of realistic, strong and provable key exchange security.

The student will be part of the Computer Science Department at the University of Oxford. The project will provide an annual stipend to the student of £23,000 per annum for 3.5 years.  The project will additionally cover the costs of university and college fees, and provision for a laptop.


The candidate is expected to have a strong background in computer science or mathematics, with an interest in applied cryptography. Candidates must have good written, communication, and organisational skills, and satisfy the usual requirements for a doctorate study at Oxford:

The studentship is sponsored by the Government Communications Headquarters (GCHQ) and the student will spend 2-4 weeks per year at GCHQ headquarters in Cheltenham. Therefore, to be considered for this studentship, the candidate has to be a UK national and been resident in the UK for ten years and has to pass GCHQ's security clearance procedures.


There is no deadline for applying. We will continue to process applications until a suitable candidate is found, and candidates are therefore recommended to apply as soon as possible. 

To apply in the first instance candidates should send their CV, a transcript with a list of courses and grades, and a motivation letter explaining why you want this studentship, to:
