Proxy re-encryption for privacy enhancement in Blockchain: Carpooling use case
Résumé
Blockchain is an especially promising and revolutionary technology that brings transparency in a scalable way
for multiple organizations and this is thanks to its several
features. There are some exciting blockchain features but
among them, decentralization is undoubtedly the most interesting one. Organizations can share data within a distributed
ledger. As a consequence, each one can access synchronized
data stored in its local Blockchain node. This functionality
improves transaction tracking and facilitates access to data
within a private group of organizations. However, in some
cases, even if organizations accept to share data, they require
to hide some private information related to their users or their
business model. To tackle privacy and trust issues between
organizations, this paper presents a blockchain architecture
based on the proxy re-encryption scheme. This scheme is integrated within smart contracts to provide a very efficient, fast,
and secure platform. The proposed architecture is implemented
in an Hyperledger Blockchain and tested in a real transport
and mobility use case.
