We are delighted to report that Dr Tom Gur has been awarded a Future Leaders Fellowship on Foundations of classical and quantum verifiable computing, funded by £892K from UK Research and Innovation. Professor Artur Czumaj, the head of the department's Theory and Foundations research theme, has commented:
We congratulate Tom and look forward to hosting this exciting project that he will lead. This prestigious award confirms the high international standing of research at Warwick in theoretical computer science and its rich interfaces with other fields.
Tom’s Future Leaders Fellowship is concerned with algorithms and cryptographic protocols, both in the classical and quantum settings, and their applications to blockchain technology and delegation of computation to the cloud. This research programme is inherently interdisciplinary, involving fundamental research at the intersection of computer science, pure mathematics, and quantum physics.
The vision that this project aims to achieve is to develop new and exciting mathematical tools and to capitalise on their power to the end of pushing the frontiers of verifiable computing; providing new methodologies for meeting the challenges imposed by big data and the societal need for decentralised systems.
Professor Sandra Chapman is part of the Centre for Fusion, Space and Astrophysics in the Physics Department and is taking part in the British Science Festival happening on campus in September.

Videos from First Labcut Workshop
Funded by the Wellcome Trust and Warwick Quantitative Biomedicine Programme (WQBP), LabCut is a science film workshop run by SynBio CDT PhD students Cansu Kuey, Charlotte Gruender and Patrick Capel. The five films created during the inaugural workshop are now available to be viewed and will be screened during the British Science Festival in September. Find out more
We’re delighted that a generous gift of $100,000 USD from honorary graduate Nicholas Donofrio has enabled the University to launch Pre-School Futures, a five year early intervention project designed and led by Dr Joanna Collingwood.
- The security, privacy and safety of connected autonomous vehicles (CAVs) has been improved thanks to testing at WMG, University of Warwick
- WMG undertook real-world testing of four innovations in the IoT-enabled Transport and Mobility Demonstrator.
- They were able to connect CAVs to other CAVs and roadside infrastructure more securely and privately.
The privacy and security of data in CAVs has been improved thanks to WMG, University of Warwick who tested four innovations that were results of the PETRAS project. CAVs can now connect to each other, roadside infrastructure, and roadside infrastructure to each other more securely.
In the near future Connected and Autonomous Vehicles are expected to become widely used across the UK. To ensure a smooth deployment, researchers from WMG, University of Warwick undertook real-world testing of four academic innovations in the IoT-enabled Transport and Mobility Demonstrator project funded by Lloyd’s Register Foundation.
The testing looked at how the vehicles will connect to each other, as well as to roadside infrastructure, and the roadside infrastructures to each other.
The four innovations tested were developed within the PETRAS Internet of Things Research Hub and aimed to improve the security, privacy and safety of future connected vehicles.
The four new innovations included:
1. Group Signatures
For a vehicle to communicate it is important that the messages it sends contain a proof that the vehicle is who they claim to be (via a digital signature). However, by revealing and proving the vehicle’s identity it allows that vehicle to be tracked over a long time. In order to provide privacy a group signature can be used, which only indicates that the vehicle is a member of a group.
The group signature scheme can be extended to use a timestamp that updates every 10 minutes as a component of the signature. Therefore, if the vehicle was to send the exact same message at 10:00am and 10:10am the group signature would differ and an eavesdropper would not be able link that the vehicle sent both messages. This scheme would be useful in vehicle platooning where vehicles want to demonstrate they are part of the platoon group.
2. Authentication Prioritisation
It is an expensive task for a vehicle to verify another’s identity. Vehicles will have limited computing resources and so will only be able to verify a specific number of identities included in messages per second. For example, if a vehicle is on a busy motorway in traffic there may already be more vehicles sending messages that can be verified in a timely manner. An adversary may also try to send many messages with incorrect signatures in order to prevent vehicles from verifying the identity of actual vehicles. Therefore the order in which the identity of messages are verified is decided based on assigning a priority to the messages. A higher priority means that those messages have the identity of the sender verified first.
3. Decentralised PKI
When a vehicle is travelling down a road it may meet multiple vehicles in a short space of time. In order to check the identity of these vehicles, the public key of the other vehicle needs to be downloaded from a keyserver. However, hosting this keyserver in the cloud has limitations due to additional communication hops increasing the time before the vehicle receives the necessary keys. Instead, vehicles can receive these keys faster if the keysever is distributed over Edge infrastructure that sits next to the road.
4. Decentralised PKI with Pseudonyms
This innovation extended the previous innovation to support periodically issuing new identities to vehicles on the road to provide privacy. Both this innovation and group signatures may be required, as they are useful in different scenarios.
Each of the techniques above were demonstrated in the real world on the campuses of the Universities of Warwick and Surrey, as well as Millbrook Proving Ground.
A follow up executive summary, informed through feedback when the work was presented at the House of Lords, is now available. The summary makes a number of recommendations, including more communication infrastructure should be deployed, and that researchers should have an ability test different types of cyberattacks on CAVs and roadside infrastructure. 5G should also be used to perform the testing, as 5G is being rolled out across the UK in the future.
Lead of the project Professor Carsten Maple of WMG, University of Warwick comments:
“The cyber-security of CAVs is key to make sure that when the vehicles are on the roads, the data is trustworthy and that vehicle communications do not compromise privacy. We tested four innovations developed in the PETRAS Project, and being able to apply them to the real world is the first major step in testing security of CAV systems.
“The units being investigated to be used in cars and on the roadside were taken to Parliament in February to demonstrate how they work; now we can focus on further testing in the real world. Future work include will include testing on 5G systems, and with different types of attacks”.
