Cryptography Apocalypse
John Wiley & Sons Inc (Verlag)
978-1-119-61819-5 (ISBN)
Computer encryption is vital for protecting users, data, and infrastructure in the digital age. Using traditional computing, even common desktop encryption could take decades for specialized ‘crackers’ to break and government and infrastructure-grade encryption would take billions of times longer. In light of these facts, it may seem that today’s computer cryptography is a rock-solid way to safeguard everything from online passwords to the backbone of the entire internet. Unfortunately, many current cryptographic methods will soon be obsolete. In 2016, the National Institute of Standards and Technology (NIST) predicted that quantum computers will soon be able to break the most popular forms of public key cryptography. The encryption technologies we rely on every day—HTTPS, TLS, WiFi protection, VPNs, cryptocurrencies, PKI, digital certificates, smartcards, and most two-factor authentication—will be virtually useless. . . unless you prepare.
Cryptography Apocalypse is a crucial resource for every IT and InfoSec professional for preparing for the coming quantum-computing revolution. Post-quantum crypto algorithms are already a reality, but implementation will take significant time and computing power. This practical guide helps IT leaders and implementers make the appropriate decisions today to meet the challenges of tomorrow. This important book:
Gives a simple quantum mechanics primer
Explains how quantum computing will break current cryptography
Offers practical advice for preparing for a post-quantum world
Presents the latest information on new cryptographic methods
Describes the appropriate steps leaders must take to implement existing solutions to guard against quantum-computer security threats
Cryptography Apocalypse: Preparing for the Day When Quantum Computing Breaks Today's Crypto is a must-have guide for anyone in the InfoSec world who needs to know if their security is ready for the day crypto break and how to fix it.
Roger A. Grimes has worked in computer security for over 30 years, specializing in host and network protection, including cryptographic systems. As a professional penetration tester, he successfully broke into every company he was hired to hack into within an hour, with a single exception that took three hours. He has been the computer security columnist for InfoWorld and CSOOnline magazines since 2005. As evangelist for KnowBe4, the world's largest security awareness training vendor, Roger speaks at major security industry events worldwide.
