This article is a transcript of the hearing of Timothée Rebours, co-founder of SEALD, editor of the eponymous software, and Thierry Leblond, co-founder of SCILLE, editor of the PARSEC software, two "zero trust" cybersecurity software, by end-to-end encryption of sensitive data on the Cloud.
Timothée Rebours, co-founder of SEALD
The issue of encryption lies in the control of who holds the encryption (de)keys, rather than in the encryption itself. The issue of data encryption comes down to two questions:
- What do we want to quantify?
- Who holds the encryption key?
Thierry Leblond, co-founder of SCILLE
With the arrival of 5G, everything will communicate with everything. We are no longer in a perimeter logic of the strong castle type, where security would be achieved through simple protection of the network, firewalls, or even probes to detect flows, etc. The billions of connected objects that will arrive are as many possible points of attack; it is therefore imperative to change the security paradigm.
When we talk about security on the Internet, we must understand that there are 3 levels of security:
- Authentication security,
- Transport safety
- The security of sharing
