On 17-18 September, we will be hosting the AlgoUK workshop at Warwick. AlgoUK is a two-day national workshop, combining a UK theory day with an additional one-day workshop focusing on applications and applied areas relevant to algorithms and complexity. The talks will take place in MS.02

In Memoriam: Josh Hill
We are deeply saddened to confirm that Josh Hill, a second year student studying Data Science has passed away in hospital overnight on Monday 10 June, following a fall in the Mathematical Sciences Building.
Head of Statistics Professor Barbel Finkenstadt said:
“The whole department is deeply saddened and distressed by the death of this lovely, gentle and kind young man. Our thoughts are with Josh’s family.”

It is with great sadness that we report the death of Prof Don Paul. Don will be remembered by many who worked with him as a brilliant scientist. He researched experimental condensed matter physics in Warwick since 1984 and created the highly successful Superconductivity and Magnetism research group.
Read an obituary here that reflects Don’s contributions to Warwick Physics and to science.
Breeding a home-grown baked bean
Dr David Gregory-Kumar from BBC Midlands Today was present to report on the harvest of the first full size field of haricot beans bred at Warwick Crop Centre by Professor Eric Holub. Watch programme from 3:37.
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”.
Mathematics at Warwick has been ranked 10th amongst Mathematics departments in the world by the Academic Ranking of World Universities (http://www.shanghairanking.com/Shanghairanking-Subject-Rankings/mathematics.html), improving its position by one place since 2018.
Imagining Futures is being exhibited as part of the British Science Festival - Felicity Boardman
I:DNA, which highlights the findings of Felicity Boardman's research project, Imagining Futures is being exhibited as part of the British Science Festival. The research explores the perspectives of people living with genetic conditions and their attitudes towards genetic screening. The installation uses spoken word, song, a large double helix structure and screens to communicate the findings of the research in an innovative and engaging way.
