Zühlke Tech Talk Berne

Welcome to the Zühlke Tech Talk in our office high above the City of Berne!

Wednesday March 20th, 2019, 5-7pm

This time, the talk is dedicated to the subject of Cyber Security:

The world’s largest public-key infrastructure has a trust problem. Here’s the fix.

All our online activities today heavily depend on various trust assumptions of the TLS encryption ecosystem, be it for private use, e-health applications, business affairs, or e-commerce. Trust is typically expressed by accepting a PKI's public root keys, on top of which a trust chain to an entity's key is constructed. These trust chains, however, have a number of problems: If any of the elements on a trust chain is compromised, the final authentication statement is meaningless, that is, impersonation and man-in-the-middle attacks occur, hence our online activities are not secure.

In the talk, we show numerous weaknesses of the world’s largest encryption ecosystem and present a blockchain-based PKI enhancement that offers fixes by automatic responses to CA misbehavior and incentives for those who help detect misbehavior. The decentralized nature and smart contracts allow for open participation, offer incentives for vigilance over CAs, and enable financial recourse against misbehavior.
