Analytical Approach to Evaluating the Effectiveness of Cryptographic Methods in Modern Information Security Systems

This study analyzes the effectiveness of modern cryptographic methods in information security systems. The research evaluates encryption algorithms based on cryptographic strength, performance, resource consumption, quantum resistance, and flexibility. A comparative analysis of AES-256, RSA-4096, ECC-384, SHA-3-512, and CRYSTALS-Kyber was conducted. The results indicate that AES-256 offers the best balance of security and speed, while post-quantum algorithms provide strong resistance against quantum attacks but require high computational resources. These findings emphasize the importance of selecting encryption methods based on specific security needs and future-proofing against quantum computing advancements.
