Radiation Hardened Rust Implementation of a Crystals-Kyber Encryption Scheme for Space Applications

It is a well-known fact that the security of traditional cryptographic techniques relies on the algorithmic complexity of solving certain mathematical problems, such as one-way functions and factorization algorithms. However, the advent of quantum computers, which can solve factorization problems at unprecedented speeds, poses a significant threat to this security paradigm. This has created an urgent need for alternative cryptographic solutions. Two primary approaches have emerged: Quantum Cryptography, which ensures security by modifying the physical transmission of cryptographic information according to fundamental physical principles, and Post-Quantum Cryptography, which adapts algorithmic processing to use techniques resistant to quantum computing attacks. Among these, the Crystals Kyber algorithm has been recognized as a candidate for new cryptographic standards. This study specifically explored the integration of Post-Quantum Cryptography within a satellite communication scenario. The project involved the design and implementation of a Crystals Kyber-based encryption scheme and an information protection mechanism leveraging error correction through Turbo codes. Both components were developed and validated using the Rust programming language, contributing to a secure communication framework suitable for future satellite networks.
