Implementing a Post-Quantum End-To-End Encrypted Messaging Service (Q20b)
Today‚ Äôs end-to-end encrypted messaging services rely heavily on quantum-vulnerable algorithms like Elliptic-Curve Diffie-Hellman. This talk will present a prototype of a post-quantum end-to-end encrypted messaging solution, which adapts the widely used messaging protocol XMPP and its encryption extension OMEMO to use post-quantum algorithms. The solution architecture will be outlined, before a demonstration of the solution is presented. Finally, this talk will discuss the main issues encountered integrating post-quantum algorithms and compare the security and performance with existing solutions.
