In recent years, cyber-attacks leveraging quantum algorithms like Shor’s and Grover’s, executed on cryptanalytically-relevant quantum computers, have demonstrated their potential to compromise and break the cryptographic systems currently safeguarding information systems. Recognizing the urgent necessity to bolster data and communication security in the quantum age, the National Institute of Standards and Technology took a significant step in July 2022 by announcing the four post-quantum cryptographic (PQC) algorithms to standardize by 2024. Notably, Kyber was chosen as key establishment algorithm, marking a pivotal transition towards quantum-safe cryptographic solutions. In the realm of space technology, current space systems predominantly rely on symmetric cryptographic primitives.
