Using Proxy Re-Encryption for vehicle data sharing

Hi all,

I think this short video clearly explains the use of Proxy Re-Encryption (PRE) for data sharing in the vehicle ecosystem.

There is also some documentation in the NuCypher website: https://www.nucypher.com/proxy-re-encryption <https://www.nucypher.com/proxy-re-encryption>

To support that Proxy Re-Encryption is not something new, this is the first paper where Proxy Re-encryption was defined, it is from 1998 ...

Of course, there are plenty of PRE schemes now a days with different security properties, variable performance and assumptions but in general, the “Proxy” should be neutral and not trying to colude with any of the parties involved in the data exchange.

We can discuss PRE and other approaches for secure vehicle data sharing in the next Best Practices meeting.
