PiQASO: Post-Quantum Cryptography As-a-Service for Common Transmission Systems and Infrastructures

PiQASO is a multi-national consortium of 2 academic institutions and 23 industrial partners from 12 EU countries. The project aspires to provide fully optimized and operational implementations as-a-service for an ensemble of crypto algorithms and protocols, including key encapsulation, digital signatures, (authenticated) key exchange, authorization, identity management, longterm data security, multi-party secure computation, providing a fully functional equivalent of Public Key Infrastructure (PKI) which is robust against future algorithmic and quantum computing advances but also practical enough to be integrated in CTS and infrastructures without the need of any additional specialist hardware to be installed on the client side, thus, enabling quantum-safe application-layer encryption/decryption services that can be consumed by any legacy system.

PACY lab is contributing in the PiQASO project to the specification of PQC services and abstractions enabling quantum-safe encryption, signing, authentication, authorization for PiQASO's PQC-as-a-Service architecture. Specifically, we are working on the design of post-quantum secure public key encryption and associated key management approaches, leveraging NIST standards, to support longterm data encryption-at-rest operations.
