Quantum computers will render current public-key cryptography (PKC) obsolete due to their ability to break hard problems. Post-quantum cryptography (PQC) algorithms are needed to replace classical PKC. The U.S. National Institute of Standards and Technology (NIST) is standardizing PQC. Lattice-based schemes are prevalent in PQC and enable Fully Homomorphic Encryption (FHE), which is the "holy grail" of computing. However, existing algorithms do not consider security against side-channel and fault attacks, which pose threats in various applications like automotive, IoT, and cloud-based applications. This project aims to strengthen collaboration between partners through visits, exchanges, joint workshops, and tutorials to enhance knowledge and human resources in cryptography. The team will analyze lattice-based PQC and FHE schemes against physical attacks and provide secure countermeasures. The collaboration will leverage the expertise of KU Leuven and IIT Kharagpur to develop secure PQC schemes and FHE protocols that resist fault attacks, side-channel attacks, and combined attacks.
