In a classical computing environment, calculating discrete logarithms for sufficiently large prime numbers is computationally infeasible, which makes the Diffie-Hellman algorithm a secure method for key exchange. However, quantum computers use a different approach to computation, based on quantum bits or qubits, which allows them to perform certain calculations much faster than classical computers. One of the computations that quantum computers excel at is the calculation of discrete logarithms, potentially allowing them to break the security of the Diffie-Hellman key exchange algorithm.

Welcome to the world of Shor's Algorithm, superposition, entanglement, and Quantum Key Distribtuion (QKD), as this new Day One documents significant steps toward quantum-resistant cryptography. The book provides a comprehensive understanding of the threats posed by quantum computing to IPsec, and the role that quantum-secure key exchange algorithms play in mitigating those threats. The stellar author list includes some the finest engineers and scientists at Juniper Networks as they convey both new knowledge and the right tools needed to protect you and your network from quantum attack.

“Quantum computing promises to herald the next major revolution in computing. Personally, for me, its application to networking and security is the most practical application in the shorter term. Day One: Quantum-Safe IPSEC VPNs is a great way to impart solid understanding of applying quantum technology to secure communication and safe key exchanges. My thanks to some of our finest leaders who form the author list for the book. Enjoy!“ Raj Yavatkar, Chief Technology Officer, Juniper Networks

“Feynman, a Nobel Prize winner for his work on QED, said: “I think I can safely say that nobody understands quantum mechanics.” Einstein called quantum entanglement (crucial to quantum networking) spukhafte Fernwirkung (spooky action at a distance). Schroedinger spoke of a cat both dead and alive. All this may lead you to think quantum networking is beyond you and you won’t even try. WAIT! Here is a practical book that tells you why you need to learn this and it gives you very practical steps on how to get into the technology. It includes hands-on training on integrating quantum-safe methods into your network and it is explained by the best in the business. Give it a shot; you won’t regret it.”- Kireeti Kompella, SVP Architecture, Juniper Networks

“Quantum technology provides new and innovative tool kits to apply for solutions in multiple fields of science and engineering, in particular computing, security and networking. For me, it’s a fascinating discipline that allows you to explore new solutions thinking out of our classical and deterministic box.“- Domenico Di Mola, GVP Optical, Juniper Networks
