Welcome to the first Cloud CISO Perspectives for August 2024. Today I’m adapting our upcoming Perspectives on Security for the Board report. It examines three key cybersecurity topics from the vantage of the board of directors: multifactor authentication, digital sovereignty, and — the one I’ll be focusing on here — post-quantum cryptography.
As with all Cloud CISO Perspectives, the contents of this newsletter are posted to the Google Cloud blog. If you’re reading this on the website and you’d like to receive the email version, you can subscribe here.

How boards can help navigate the quantum leap
By Phil Venables, VP, TI Security & CISO, Google Cloud
Quantum computers are a hot topic in the tech world. They’re a new type of machine that uses quantum mechanics to solve complex mathematical problems that can stump today’s computers — and they could pose a risk to existing cybersecurity technology and practices.
If powerful enough, quantum computers could potentially crack the codes, or encryption, that protect our online communications and sensitive data. This could have serious consequences, jeopardizing online privacy and the security of our digital world. We’re already seeing cyberattacks where threat actors steal vast troves of encrypted data.

One reason they might have for doing that is to decrypt the data at a later date. In one anticipated scenario, these threat actors use the quantum computers of the near future to access data that today would be considered inviolate.
Fortunately, there are alternative cryptographic systems known collectively as post-quantum cryptography (PQC) that offer a secure way forward. Standards to guide the development of “quantum-safe” cryptographic systems have just been finalized by National Institute of Standards and Technology (NIST) — and they run on today’s conventional computers.
At Google, we take these risks seriously, and we’re taking steps on multiple fronts to address quantum computing risks. We began testing PQC in Chrome in 2016, we’ve been using PQC to protect internal communications since 2022, and we’ve taken additional quantum computing protective measures in Google Chrome, Google servers, and in experiments for connections between Chrome Desktop and Google products (such as Gmail and Cloud Console.)
Additionally, Google engineers have contributed to official, formal quantum computing standards released by NIST, ISO, and other standards organizations, and we are working with partners to produce formally-verified PQC implementations that can be used at Google and beyond.
Board members should understand the consequences of not preparing for PQC, and ask questions of their organization’s leaders including the CISO, CIO, and CTO, and despite the unpredictable timeline for quantum breakthroughs.
There are four primary reasons that drive our interest in getting ready for PQC now — and not delaying action.
Business impact of cryptography failing. Quantum attacks could be able to break the cryptography used to protect data critical to delivery of your most important business services.Migrating cryptography takes a long time. Although quantum-safe cryptographic algorithms are available and can be implemented on existing hardware, upgrading to new cryptographic algorithms and protocols requires significant time and effort.Harvest now, decrypt later. Future technology could unlock the secrets hidden in data that cybercriminals are stealing today — secrets that could be the very lifeblood of your organization, such as intellectual property, trade secrets, and sensitive communication records.Standardization and upcoming regulations. Well-recognized standards bodies, including NIST, have just released post-quantum cryptography standards. Even the White House is developing directives urging federal agencies to prepare for quantum computing advancements. We anticipate new regulations across various industries, and Google is actively participating in working groups such as the Financial Services Information Sharing and Analysis Center (FS-ISAC) and the PQC Alliance to address these developments.
From PQC preparation to PQC action
Preparing for PQC doesn’t need to be managed as a “big bang”. Board members should speak with their CISO, CIO, and CTO about developing a post-quantum cryptography strategy. This should include preparing for integration of new, quantum-resistant algorithms into existing systems, while ensuring efficiency and scalability and weighing cost, risk, and usability.
Implement a PQC strategy: Acquire expertise to distinguish between hyped up announcements of small improvements, marketing, and actual advancement in quantum engineering. Follow up with both industry best practices including our post-quantum cryptography blogs and academic and industry research, including Google’s Quantum Research.Assess the business risk: Conduct a risk assessment to identify critical data that is most vulnerable to quantum attacks. Identify where cryptography is utilized — it is likely pervasive throughout your systems. Create an inventory of all systems employing cryptography to safeguard data at rest, in transit, and in use. Classify the data and perform a threat analysis. Google’s quantum threat analysis can serve as an example of how to determine which changes should be addressed first.Analyze the broader risk: Assess the wider impact to other systems that might need to change. This could be like a Y2K problem where the format of data (for example, larger digital signatures) in databases and applications might need significant software changes beyond the cryptography.Learn from the past: Reflect on how your organization successfully dealt with major cryptography-related issues in the past. This will help identify strategies that worked well and areas for improvement. Organize a tabletop exercise — a workshop for the organization’s leadership (and board members) to raise awareness of the complexities associated with migrating cryptographic systems — and to identify the necessary steps moving forward. Google’s adoption of PQC can serve as an example for other organizations.
To be clear, we’re not sure of exactly when we’ll see a quantum computer powerful enough to break today’s security. Whether it happens in 5, 10, or 15 years, the task of adopting post-quantum cryptography is substantial.
Additionally, with NIST’s new PQC standards, regulators, governments, customers, and auditors are likely to question your organization about its PQC plans. Therefore, it’s crucial for organizations to initiate the transition immediately.
