Full Description
A practical guide to navigating cryptographic challenges in the era of quantum computing.
Becoming Quantum Safe: Implementing Post-Quantum Cryptography to Mitigate Risks and Protect Your Business is a is a definitive, pragmatic guide designed for CISOs, CTOs, CIOs, CROs, CCOs, CDOs, DPOs, security leaders, and technology executives who need to understand and act on the challenge posed by quantum computing to current cryptography. This comprehensive playbook delivers step-by-step strategies for transitioning to Post-Quantum Cryptography (PQC)—ensuring your organization remains secure, compliant, and resilient in the quantum era.
Authored by leading experts in cybersecurity, cryptography, and quantum technologies, this book demystifies the quantum threat, explains the vulnerabilities in today's encryption, and provides clear, actionable guidance to achieve crypto-agility and implement quantum-safe cryptography.
What You Will Learn:
What is Quantum Computing and how it Threatens Current Encryption
Understand the basics of quantum computing and the challenges it poses to RSA, ECC, and other widely used encryption. Gain explanations of Shor's Algorithm, Grover's Algorithm, and how they impact classical cryptography.
Practical Crypto-Agility Strategies
Learn how to build a crypto-agile enterprise—one that can rapidly adopt, test, deploy, and manage new cryptographic standards without disrupting business operations.
A Roadmap to Post-Quantum Cryptography (PQC) Adoption
Follow a proven, step-by-step framework to transition from classical to quantum-safe cryptography. Identify key milestones, address operational challenges, and implement solutions that safeguard data, operations, and digital trust. Learn about the consortia work that brings together players in the ecosystem and how one can leverage the work being done to accelerate the quantum safe journey.
Case Studies Across Industries
See how global leaders in banking, financial services, government, telecommunications, healthcare, and retail are adopting post-quantum cryptography to mitigate risks, achieve compliance, and future-proof their security infrastructure.
Why This Book Matters Now:
The quantum threat to encryption is real and time-sensitive. Quantum computers will render today's encryption obsolete, exposing sensitive data, customer trust, and business continuity.
Regulatory pressures are rising. Governments and standards bodies across the globe are mandating quantum-safe transitions.
Organizations that embrace crypto-agility today will lead the future, maintaining a secure competitive edge in a quantum-powered world.
