Quantum Distribution Oblivious Transfer
Q.DOT is a research project, which will contribute to the creation of new
trustable and privacy technologies, with main focus to vehicular networks.
This project will implement Secure Multiparty Computation (SMC) for vehicular networks,
specifically to calculate the average speed of of a vehicle.
The consortium of Q.DOT is composed by
Instituto de Telecomunicações (IT),
namely the Optical Quantum Communications and Technologies Group (OQCT-Av) at IT Aveiro and
the Security and Quantum Information Group (SQIG-Lx) at IT Lisbon.
We will explore a new generation of cryptographic technologies, based on the realization
of both high-speed and secure quantum oblivious transfer (OT) cryptographic primitive for the statistical analysis of
private databases - Privacy Preserving Data Mining (PPDM).
Design a method capable of calculating the average speed of the road traffic by vehicle category,
in a given location, and at the same time ensuring the privacy of the collected data;
Development SMC-based technology based on quantum oblivious key distribution (QOKD).
Development of a protocol for the generation and distribution of oblivious keys;
Implementation of a quantum communication physical system based on single photon encoded
in the polarization;
Integration of the protocol with the quantum communication physical system;
Test and validation of the quantum technology developed for SMC use case.

Altran R&I Workshop on Quantum and Q.DOT Project
Altran organized an internal workshop dedicated to Quantum Technologies, more specifically to the Q.DOT project on
26st November 2020. The programme of this event includes a presentation of the Quantum area challenges,
as well as the components of Secure Multiparty Computation (SMC). In addition, an overview of the Q.DOT project will be made regarding
its main information, objectives, structure and conceptual approach. The architecture design and the use case defined within the scope of
the project will also be presented. Finally, a first demonstration of the work already done by Altran in the Q.DOT
project will be presented.
Visit of the Q.DOT consortium to IT
On 29st September 2020, the consortium visit Instituto de Telecomunicações at University of Aveiro. The laboratory implementation of the quantum communication system based on single photon encoded in the polarization was presented.
