A Comparative Study Of Symmetric And Asymmetric Cryptographic Algorithms For Enhancing Data Security In Cloud Computing
Year: 2025
Type: article
Abstract: This paper provides a comprehensive comparative analysis of symmetric and asymmetric cryptographic algorithms, contextualized for the unique security landscape of cloud computing. We conduct an in-depth examination of the core principles, architectural designs, performance benchmarks, and key management complexities of prominent algorithms such as AES, DES, RSA, and ECC. The study evaluates their application in mitigating pervasive cloud security challenges, including securing data at rest and in transit, and addressing risks in multi-tenant environments. A central focus is the analysis of the hybrid cryptosystem, exemplified by TLS/SSL, as the de facto standard for secure communication. Furthermore, the paper explores advanced and future-facing cryptographic paradigms. It investigates Homomorphic Encryption, assessing its potential for privacy-preserving computation against its current performance limitations. Critically, it analyzes the existential threat posed by quantum computing to current public-key infrastructures and details the ongoing global effort toward standardizing Post-Quantum Cryptography (PQC), with a focus on lattice-based solutions. The paper concludes with strategic recommendations for cloud architects and security professionals, emphasizing the necessity of a crypto-agile posture to navigate the evolving threat landscape and ensure long-term data security in the quantum era.
