D7.5 First Version of the Privacy Enhanced Digital Currency Prototype

This deliverable describes the ATOS privacy-enhanced digital currency use case prototype at the end of the second year of the project. It describes the cryptographic protocol related to Functional Encryption schemes and how they integrate into a payment platform based on blind signature cryptographic scheme. This document presents the first version of the pilot which has been developed as a proof of concept to check the viability of the design. The version presented should serve as base to be extended to fulfil the objectives of the use case.
