The Case

Public key cryptography has developed into a crucial aspect of the digital communication infrastructure in all over the world during the past three decades. Mobile phones, internet shopping, social networks, and cloud computing are only just a few of the numerous applications supported by these networks which are of the utmost importance to our economy, security, and way of life.

The ability of people, organizations, and governments to communicate securely is crucial in such a connected world. Since there are currently no quantum computers that can perform Shor’s and Grover’s algorithms on long keys, the quantum threat is only theoretical at this time. However, it is clear that current cryptosystems like RSA, ECDSA, ECDH, and DSA will need to be replaced by post-quantum cryptography (PQC) as soon as possible.

Several pertinent organizations have acknowledged the importance of addressing this issue as fast as possible. In this regard, the National Institute of Standards and Technology (NIST) recently launched an initiative to identify cryptographic algorithms resistant to quantum computer attacks by 2022 and make them accessible by 2024.

The PQ-REACT solution

Utilizing Europe’s most potent quantum infrastructure (the IBM Quantum Computer from Fraunhofer FOKUS), the
PQ-REACT primary objective is to design, develop, and validate a framework for a faster and simpler transition from
classical to post-quantum cryptography for a broad spectrum of contexts and usage domains.

This framework will incorporate PQC migration routes, cryptographic agility techniques, and a toolkit for validating
post-quantum cryptographic systems. Users can switch to post-quantum cryptography through this framework, considering their unique circumstances, different contexts, and a wide range of real-world pilots, such as Smart Grids, 5G,
and ledgers.

Further, the project will also foster a series of open calls for SMEs and other stakeholders to bring and test their PQC
algorithms and external pilots on the PQ-REACT, Quantum Computing Infrastructure.

About The PQ-REACT project

The PQ-REACT project aims to design, build, and validate a framework for a quicker and more effortless shift from classical to post-quantum cryptography for various contexts and usage domains.

This framework will include cryptographic agility techniques, PQC migration paths, and a toolkit for validating
post-quantum cryptographic systems, enabling users to switch to post-quantum cryptography while considering their
unique circumstances and preferences.

The Challenges

Assessment of the cryptographic components in existing technology infrastructures and migration roadmaps towards PQC era

Cryptographic agility

Validation of new PQC algorithms and cryptanalytical methods

QKD and PQC coexistence

Legal aspects of post-quantum mitigation

The Objectives

Design and build a framework for a faster and smoother transition from classical to post-quantum cryptography for a wide variety of contexts and usage domains.

Design architectures and develop innovative approaches and tools that enable cryptographic agility and
migration to new cryptographic algorithms and standards in an ongoing way.

Build an open platform that will provide a portfolio of tools around an actual quantum computer, for evaluation of PQC algorithms and cryptanalytical methods.

Demonstrate the project outcomes with a set of relevant pilot demonstrators.

Maximize the impact to streamline the migration to quantum-resistant cryptography assets. A realistic
and meaningful uptake will require validating the performance and transferring knowledge among a European ecosystem of researchers and SMEs capable of capitalising on the funding and guidelines.

The Ambition

The ambition of PQ-REACT is to create a bulwark against the imminent threat that quantum computing poses to
the cryptographic underpinnings of the digital world.

The project’s focus is not merely academic; it aims to tackle the practical complexities involved in transitioning from
classical cryptographic systems to quantum-resistant ones.
Given the pervasive use of public key cryptography in contemporary digital infrastructure, PQ-REACT seeks to forge a
robust pathway for the industry’s shift to post-quantum cryptographic systems.

Key Goals

Comprehensive
Assessment

PQ-REACT aims to carry out a detailed
evaluation of the cryptographic components
in existing IT and OT systems.
The project will develop tools that assist
organizations in identifying their vulnerabilities
and in formulating migration strategies tailored
to their specific needs.

Optimization
and Trade-offs

Recognizing the diversity of computing systems
that serve society, PQ-REACT is committed to
exploring optimal trade-offs among the
configurable parameters of PQC algorithms.
This includes factors like computation time,
communication overhead, and various system
constraints such as power consumption and
bandwidth

Migration
Roadmaps

Practical, actionable roadmaps for the shift to
PQC will be a central deliverable of the project.
These roadmaps will be customized to meet
the distinct requirements and priorities of
different technology infrastructures, thereby
enabling a seamless and secure transition to
the post-quantum era.

Interoperability

The project acknowledges the complexities
arising from the layered and heterogeneous
nature of current systems.
As such, PQ-REACT aspires to ensure that
new cryptographic standards are
backward-compatible with existing
technologies, thus facilitating a smoother
migration process and minimizing
operational disruptions.

Open Calls for SMEs

Understanding the critical role that small and
medium-sized enterprises (SMEs) play in
technological innovation and implementation,
PQ-REACT plans to initiate open calls that
attract these businesses.
The aim is to engage SMEs in contributing to
the development, testing, and scaling of
post-quantum solutions, thereby enriching the
project with diverse perspectives and expertise.

Education and Awareness

In addition to its technical goals, the project is
committed to raising awareness about the
urgency of migrating to quantum-safe
cryptographic systems.
This will be accomplished through the creation
of educational materials, white papers, and
symposiums aimed at disseminating key
insights and knowledge.

The Pilots

PQC for Smart
Grid applications

Application of Quantum Resistant
Crypto to Smart Grid deployments

QKD on
5G networks

Converged QKD and PQC
application for next-generation
networks (5G and beyond)

Post Quantum
enabled Blockchain

The Open Calls

The program will run two open calls that will allow the selected SMEs and technology providers to obtain optimized solutions to solve cryptographic encryptions based on classic algorithms that currently protect data and infrastructure, and this way will enhance Europe’s leadership in the global cybersecurity economy, as PQC is a vital
enabler for the protection and strengthening of critical infrastructure and services.
