Smart energy meters upgraded with PQC capabilities via testing and evaluating the efficiency of PQC algorithms in real smart energy meters (loT) considering H/W limitations, bandwidth, length of Digital Signature PQC algorithms keys and signatures, CPU and memory usage, etc.

Leveraging PQC and QKD hybridisation approaches related to 5G and their evolution to 6G architectures. PQ-REACT will investigate their application to significant use cases, especially related to protection mechanisms for the network infrastructure, addressing the security and performance requirements in highly-pervasive, critical networked environments.

Test and validation of innovative services/apps that use PQC algorithms, extending beyond existing liboqs-based applications such as cURL, Nginx, and HTTP, to include new PQC enablers for protocols across communication, authentication, and network security domains. These enablers can support, for example, QUIC and SIP for secure transport and real-time communications, DNSSEC for quantum-safe domain integrity, and authentication frameworks like OAuth2, OpenID Connect, and Kerberos to resist quantum attacks.

Practical validation and assessment of the resilience of new applications/solutions using PQC techniques, exploiting the capabilities of an HPC (High-Performance Computer) or QC (Quantum Computer) via a suite of tools (C++/Python/Qrisp). Additional tools like Quantum Approximate Optimization Algorithm (QAOA), Shor’s algorithm, algorithmic primitives (e.g., quantum Fourier transform (QFT), quantum phase estimation (QPE)) and solving QUBO problem instances with QAOA are available in Qrisp.
