This study evaluates its performance in execution time, CPU, and RAM usage across different message sizes, security levels (Dilithium-2, 3, 5), and pre-hashing. The results show linear scaling with message size, modest overhead at higher levels, and major speed gains when pre-hashing large files. Dilithium-2 provides optimal efficiency, while Dilithium-5 delivers stronger protection with practical performance. Beyond civilian use, Dilithium is well-suited for military systems, enabling secure communications, long-term confidentiality of classified data, and NATO interoperability, even in constrained environments such as tactical radios, drones, and field IoT devices.20262026-10-08 10:23:24Neznano1683UDK: 004:512.624.95:355/359ISSN pri članku: 2463-9575COBISS_ID: 294199555sl
