Abstract:
Transport Layer Security 1.3 is the latest version available. This protocol is widely used in Internet security, present in more than 60% of all Internet connections based on HTTPS. Quantum computers are a new computational paradigm that threatens information security as we know it, solving mathematical problems used in current cryptography in polynomial time or providing quadratic acceleration for brute force attacks. This paper highlights the quantum threat to Transport Layer Security, focusing on public key cryptography, exposes threat scenarios, propose a detailed attack model to the protocol, shows expected storage requirements to store-now-decrypt-later attacks, and explores ways to mitigate these quantum threats.
