| Acronym: QUESTS |
| Main Objective: QUESTS will engineer a universal quantum-enabled secure multiparty (SCM) computation framework suitable to be used in vehicular networks. SMC allows cooperation in the cyberspace between untrusted parties with full security and privacy. Oblivious transfer is a fundamental primitive for SMC. Based on a novel hybrid approach, quantum and classical, that we developed for the generation of oblivious keys, we will implement oblivious transfer in a way that surpass in terms of speed and security any know classical implementation. This secure and fast oblivious transfer has the potential to make SMC-based services broadly available, if the generated quantum oblivious keys can be securely distributed to every device in the network. We will investigate and propose a distribution network for quantum generated oblivious keys, in a way that makes possible to disseminate the keys for many end-devices. The end-devices, cars in the case of a vehicular network, are not wired therefore a final radio link will also have to be considered. The ability to distribute securely quantum generated keys to mobile devices is a fundamental step to integrate quantum technologies in modern complex and heterogeneous communication systems. As proof-of-concept, we will focus on a service to vehicular networks. Vehicular networks can play a major role in the future of mobility, but their full potential can only be unveiled if the parties can cooperate in a full secure and privacy respectful way. Therefore, implementing a secure multiparty computation service in a vehicular network can have a huge societal impact, but also raises major engineering challenges due to the large number parties involved and due to the mobility of end-users, which demands the novel approaches that will be pursued in the QUESTS project. |
