PRISEC III: Cryptographic techniques for enhanced security
| Resumo: | This project presents PRISEC III, a cryptographic framework designed to improve the security and efficiency of IoT environments with limited resources. It features a four-tier encryption model - Guest, Basic, Advanced, and Admin - which balances security and performance by using increasingly sophisticated encryption techniques. PRISEC III integrates both symmetric (AES, ChaCha20 and Blowfish) and asymmetric (ECC and RSA) encryption to optimise efficiency and ensure secure key exchange. Lower tiers use lightweight encryption to reduce computational overhead, while higher tiers apply multi-layer encryption for critical operations. Hybrid encryption and edge computing further enhance scalability and resource optimisation. Performance evaluations confirm PRISEC III’s ability to provide secure, scalable data transmission while addressing IoT limitations. This research offers a structured approach to selecting cryptographic protocols, contributing to the development of efficient, adaptive security solutions for IoT applications. Keywords: Cryptographic algorithms, asymmetric and symmetric encryption, multi-level encryption, computational efficiency, hybrid encryption techniques. |
