Comprehensive Strategies for Mobile Data Security in Cloud Computing Using Advanced Cryptographic Techniques

Abstract

One of the major challenges in cloud computing environments is data security, especially for mobile data applications where efficiency and throughput are critical. To evaluate the effectiveness of advanced cryptographic algorithms in mobile data security, this paper discusses symmetricencryption (AES), asymmetric encryption (RSA), elliptic curve cryptography (ECC), homomorphic encryption, and blockchain. While RSA guarantees secure key exchange, AES is considered the fastest and most energy-efficient encryption. ECC is also suitable for low-resource devices due to its provision of strong encryption with smaller keys. Blockchain is ensured to offer
decentralized security that is immutable in nature, and homomorphic encryption ensures safe computation without revealing plaintext. A hybrid cryptographic security algorithm is proposed with the benefits of both approaches so that encryption can be maximally efficient, secured, and at high speed. The performance metrics state that the combined technique is perfect for
transmitting and storing data safely in cloud environments since this balances computational overhead, efficiency of storage usage, and security level. Findings indicate that it is essential to make use of multiple encryption techniques to improve security without making efficiency compromise.
