Post-Quantum Cryptography Alliance PQCA
The Post-Quantum Cryptography Alliance (PQCA) was formally established by the Linux Foundation in February 2024 as a major step to protect the digital future. In order to address the significant security issues raised by the emergence of quantum computing, this new project unites an extraordinary coalition of market leaders, researchers, and developers, including well-known companies like Google, IBM, Amazon Web Services, and Cisco. In order to ensure that our digital infrastructure is resilient to future quantum attacks, the PQCA’s main goal is to promote the development and broad use of post-quantum cryptography (PQC).

The Looming Quantum Threat to Modern Encryption
At the core of today’s digital security environment is public key cryptography. Important protocols like Transport Layer Security (TLS), which protects “https” websites, and digital signature methods, which are necessary for software package verification, are supported by it.
But the quick development of quantum technology has made a long-standing theoretical threat far more plausible. In 1994, Shor’s algorithm was created, proving that it could theoretically crack popular cryptography based on elliptic curves and RSA. Although this threat was mostly theoretical for many years, recent developments in quantum technology indicate that building sufficiently powerful quantum computers may become possible. Such devices have the ability to decrypt almost all modern communications once they are up and running, so seriously jeopardizing the security of any system or person that depends on the cryptographic techniques used today.

Omkhar Arasaratnam, general manager of the Open Source Security Foundation (OpenSSF), another Linux Foundation project, emphasized the seriousness of the matter by saying that quantum computing “is real” in its danger to contemporary encryption. The National Institute of Standards and Technology (NIST) has estimated that “sufficiently powerful quantum computers will easily compromise the cryptography,” and he issued a warning that such systems might appear as early as 2030.
A large-scale quantum computer “would be able to break modern public key encryption algorithms that are widely used in our IT infrastructure,” explained Douglas Stebila, associate professor of cryptography at the University of Waterloo and co-founder of the Open Quantum Safe (OQS) project. This makes post-quantum cryptography the creation and application of cryptographic methods especially made to withstand quantum computation urgently necessary.

The Genesis of the PQCA: A Call for Coordinated Action
Talks at the Linux Foundation Member Summit in Lake Tahoe gave rise to the idea for the Post-Quantum Cryptography Alliance. A vital component was still lacking, despite the fact that post-quantum cryptography research has attracted a lot of attention from a variety of organizations, including governments, businesses, and universities, and that projects like NIST’s Post-Quantum Cryptography Standardization Project and the Crypto Forum Research Group within the Internet Engineering Task Force have made progress. One thing that was found lacking was a cohesive, well-coordinated effort from all of these players to promote and ease the real-world application of these new algorithms.
The realization of a truly post-quantum future depends on the successful implementation and broad adoption of research and standardization, which are essential first stages. Additionally, software implementations that are not just widely used, dependable, and open source are desperately needed to guarantee widespread use of these crucial methods. This is the exact gap that the PQCA seeks to address, stepping in to offer the required structure for this cooperative activity. For enterprises who align with the Cybersecurity Advisory of the U.S. National Security Agency, the Alliance serves as a central basis.

Dual Goals: High-Assurance Software and Continuous Innovation
The PQCA’s main objective is to promote post-quantum cryptography use. This will be accomplished through two main, related sub-goals:
- Producing High-Assurance Software Implementations: The Alliance is dedicated to developing dependable and strong software applications for standardized algorithms. This involves compiling several implementations that already exist and making sure they are prepared for production use in order to promote industry-wide adoption. The goal is to unite big and small businesses to develop, test, and implement these novel algorithms while supporting their incorporation into current systems.
- Supporting Continued Development and Standardization: As the subject of post-quantum cryptography is always changing, the PQCA also seeks to encourage the continuous research and standardization of new post-quantum algorithms.

Current Projects Under the PQCA Umbrella
At the moment, the PQCA is working on two major initiatives that are essential to its purpose. Initially developed at the University of Waterloo, Open Quantum Safe (OQS) is an open-source project that has been in development for more than ten years. A C library for quantum-resistant cryptographic algorithms, liboqs, and prototype integrations into popular protocols and applications, such the OpenSSL library, are all part of OQS. The goal of this research is to facilitate the switch to encryption that is resistant to quantum errors.
PQ Code Package is the second important project. Building formally verified, high-assurance software implementations of post-quantum cryptography algorithms that adhere to standards is the main goal of this project. Its initial focus is on the algorithm chosen for standardization, ML-KEM (Kyber). One workable public key encryption method that can give popular protocols like TLS and SSH quantum-resistant secrecy is ML-KEM (Kyber). The goal of these initiatives is to help post-quantum cryptography become more widely used.

The Road Ahead: Collaboration and Agility are Key
To further develop the community and influence the direction of digital security, the PQCA is actively seeking collaboration on ongoing post-quantum cryptography projects. GitHub makes the Open Quantum Safe and PQ Code Package projects easily accessible, allowing for instant feedback and cooperation. Additionally, the Alliance is always open to suggestions and submissions for new initiatives that it should support or take on. Developing software that supports cryptographic agility or PQC migration, as well as infrastructure to make it easier to adopt and test new post-quantum algorithms, are examples of future development. During the transition phase, systems’ capacity to quickly switch between several cryptographic methods is known as cryptographic agility.

As Douglas Stebila pointed out, switching to quantum-resistant algorithms is a huge undertaking rather than just a technical difficulty. He stressed that “it takes a long time to deploy new technology, and this will be the most complex cryptographic migration ever conducted”.
This urgency is exacerbated by the “store now, decrypt later” threat, which states that bad actors may save critical communications that have been encrypted today and decrypt them later when powerful quantum computers become accessible. Stebila went on to say that “as we become more reliant on digital systems, the potential impact of quantum-enabled cryptographic breaches becomes more significant” . It is imperative that we begin this shift as soon as possible in order to defend our national security and digital interests by ensuring readiness and defense against quantum threats before they become real.

A “neutral, trusted hub for developers to code, manage, and scale open technology projects,” the Linux Foundation offers the perfect setting for this vital cooperative endeavor. Any Linux Foundation project ultimately depends on people investing their time and energy to contribute code and foster the community.
The Alliance welcomes everyone who wants to help ensure a post-quantum future that is safe and dependable. “A crucial initiative to ensure developers can access robust cryptographic libraries that implement post-quantum cryptography in various popular languages” is how the OpenSSF has declared its strong support for PQCA. The goal of this united front is to provide developers with the resources they need to safely transition to hybrid or entirely post-quantum cryptography.
