An Efficient Security Solution for IoT and Cloud Security Using Lattice-Based Cryptography

This study introduces lattice-based cryptography to enhance security in IoT and cloud systems. It focuses on two fundamental challenges in lattice-based encryption. The paper compares the advantages and disadvantages of lattice-based encryption with traditional RSA and elliptic curve cryptography. Furthermore, it presents a novel approach called “Lattice-based secure data aggregation,” specifically designed for IoT and cloud systems, ensuring confidentiality and integrity during data aggregation. The paper covers various aspects, such as data encryption, aggregation, decryption, and implementation on resource-constrained devices. Performance and security evaluations compare the proposed algorithm with other data aggregation techniques, demonstrating its effectiveness against attacks, computational efficiency, and low memory requirements. The paper also addresses the approach's limitations and proposes potential areas for future research. Overall, the proposed lattice-based cryptography offers a promising solution for privacy and security-sensitive IoT and cloud systems, making it a viable option for widespread adoption.
