Quantum Threat: PKI Security & PQC Solutions

The quantum threat is a significant concern as quantum computing grows in popularity and profoundly alters the digital landscape. Quantum computing used to be an intellectual curiosity from the middle of the 20th century, but now it is a promising fact. The ideas that make this technology so powerful come from the complicated field of quantum physics. Richard Feynman and David Deutsch were pioneers in this uncharted area. They used superposition and entanglement to process information in ways that were thought to be impossible with traditional computers. Their pioneering work set the stage for what is now a busy field of study and development that has a big impact on many fields, especially digital security.

Since these early theoretical works, quantum computing has advanced notably, highlighted by IBM’s 127-qubit Eagle processor in 2021. Despite these advancements, practical threats to cryptographic systems by quantum computers remain theoretical at this stage.

We also look at how Public Key Infrastructure (PKI) has changed over time. Whitfield Diffie and Martin Hellman conceived the idea of PKI in 1976. It was a groundbreaking idea that laid the groundwork for safe digital communication. By using a set of mathematically linked keys—one private and one public—PKI has helped make it possible for digital transactions to be safe, secure email, digital signatures, and many other important web services to work. This dual-key framework has been a strong defense against many security threats, allowing private contact and data protection in a world that is becoming more and more connected.

However, the rise of quantum computing poses a significant threat to the security guarantees offered by standard PKI systems. With its incredible computing power, the quantum realm can penetrate the fortress that PKI has constructed over the years. This could make our digital world open to security threats that have never been seen before.

In this article, we will explore how quantum computing endangers the traditional security infrastructure of PKI, examine potential countermeasures, and discuss SSL.com’s vital role in aiding organizations through this challenging transition.

Quantum Threat: PKI Systems in Danger Due to Quantum Computing

Even though quantum computing has the potential to improve technology and help solve problems, it poses a major threat to the security of standard PKI systems. The problem comes from the fact that some cryptographic methods, like RSA and Elliptic Curve Cryptography (ECC), are not as secure as they could be.

In the old days of computers, RSA and ECC were the mainstays of digital security. RSA, named after its creators Rivest, Shamir, and Adleman. It is based on the fact that factoring big numbers is hard to do on a computer, and most people think that classical computers can’t do it. In the same way, ECC is based on the hard task of figuring out discrete logarithms in a finite field. The secure key exchanges in PKI systems, which are a big part of our modern digital security infrastructure, are based on these math problems, which are easy to set up but very hard to solve.

But the rules are different in the quantum world. Enter Shor’s algorithm. In 1994, mathematician Peter Shor came up with a quantum algorithm that could factor big numbers and do discrete logarithms faster than any known classical algorithm. This made RSA and ECC-based PKI systems vulnerable. If there was a strong enough quantum computer, Shor’s algorithm could figure out what private keys are from what public keys are. This would break the privacy that PKI systems are meant to protect.

The fear is not just an idea. A 2021 study by the National Institute of Standards and Technology (NIST) suggests that quantum computers capable of breaking RSA-2048 encryption, commonly employed in many PKI systems, might emerge within the next two decades.

This prediction shows how serious and urgent the danger that quantum computing poses to our current PKI systems is.

So, the security of our digital world is in danger as the promise of quantum computing moves from the theoretical to the real world. How, then, can we navigate this impending quantum revolution without jeopardizing our digital security systems? This becomes the most important question.

Addressing the Quantum Threat: The Solution of Post Quantum Cryptography (PQC)

Post Quantum Cryptography (PQC), which is also called quantum-resistant cryptography, is a potential way to deal with the problems that quantum computing poses. PQC is the next step in securing digital communication. It does this by creating new cryptographic systems that can resist attacks from both traditional computers and quantum computers.

Lattice-based cryptography is one of the more interesting methods in PQC. This method takes advantage of the fact that lattice problems in high-dimensional space are hard and have no good answers in either the classical or quantum worlds. This makes lattice-based cryptography a good choice for making cryptographic systems that can’t be broken by quantum computers.

Multivariate polynomial equations are the basis of multivariate cryptography, which is another method. This method of encrypting information is safe because it is hard to solve systems of multivariate equations over a small field. Classical computers can make these kinds of systems quickly, but even quantum computers have a hard time fixing them.

Hash-based cryptography, the third method, is one of the oldest and best-studied ways to use cryptography after quantum computers. Hash-based systems, which use the ideas behind cryptographic hash functions, have been shown to be safe from quantum threats. So, they are a tried-and-true option for companies that want to protect their cryptographic systems from the quantum threat.

Together, these PQC techniques pave the way for a new era of cryptographic systems that might be able to keep up with improvements in quantum computing. Exploring and using these methods, on the other hand, requires a lot of technical knowledge and careful planning, which SSL.com is the only company that can provide.

What the government needs to know about quantum cryptography

Adopting Post-Quantum Cryptography isn’t just a matter of technology; there are also a lot of legal and safety issues to think about. As PQC is a relatively new area, standards and rules are still being set and made official. This creates an ever-changing landscape that organizations must learn to navigate.

Several regulatory groups and standards organizations around the world, such as the National Institute of Standards and Technology (NIST) in the United States, are working hard to set PQC standards. As these guidelines take effect, organizations will need to make sure that their cryptographic systems follow them, balancing the need for more security with the need to follow regulations.

Also, the switch to PQC could make it harder for organizations to follow privacy and data protection laws, like the General Data Protection Regulation (GDPR) in the European Union. Organizations need to think about how to make sure the change goes smoothly without lowering data security standards.

Recent advancements include NIST’s post-quantum cryptographic standards, such as the inclusion of Crystals-Kyber and Crystals-Dilithium, critical for organizations to align with, particularly in sectors relying on robust encryption for data protection.

We at SSL.com can help companies find their way through all of these challenges. SSL.com can help businesses stay compliant during the transition process by giving expert advice on changing PQC standards and rules. With the company’s technical know-how and deep knowledge of the regulatory landscape, organizations can confidently move toward quantum-resistant cryptography without sacrificing compliance requirements.

Case Studies: Responding to the Quantum Threat with Post-Quantum Cryptography

Post Quantum Cryptography (PQC) is starting to show how it can be used in the real world, which shows that it is possible and necessary to switch to PQC. Across the digital world, there are many case studies and experiments that show this is true.

In 2022, Google tried out PQC in its Chrome Canary browser. This is a good example. In this pilot project, Google worked with a post-quantum cryptography startup called CECPQ2 to make a key-exchange algorithm that works with post-quantum encryption. This test implementation showed what it would be like to use PQC in widely used web applications and showed some of the options that lie ahead.

However, transitioning to PQC is not without its challenges. To make sure that a new cryptographic system is secure and works well, it is important to carefully plan, test, and keep an eye on it. Organizations must also make sure that their new systems can still talk to older, non-PQC systems during the change phase. This is called “backward compatibility.”
