Exploring on Cloud Security Landscapes:A Comprehensive Review

Nowadays, the massive growth of data and the adoption of the cloud-based architecture indicate that the secure storage of data is a very essential issue. Cloud storage is the solution to convenient, scalable and cost-effective storage, yet security issues persist, especially regarding the protection of sensitive information. The encryption plays a vital role in which data is made unreadable and only accessible by those with the proper authorization. This helps in data management and minimizes data leaks. Shared responsibility in cloud security entails collaboration between the operators and users through the encryption strategy and a number of security measures to protect the data, apps, and infrastructure. This paper deals with the different cryptographic techniques and technologies used for improving cloud security. It discusses the notion of Non-Deterministic Cryptographic Scheme (NCS), which is a secure technique that effectively utilizes randomness in cryptographic algorithms. Regarding the Intel architecture compatibility, SGX and blockchain technology implementation not only ensures data immutability, but it also strengthens the data against cyber threats. SGX produces secure compartments inside cloud platforms, while blockchain makes data integrity possible through decentralized and immutable ledger technology. The research gives an impression of the seaside and multi sided cloud security. Involving encryption, access control, data loss prevention, and intrusion detection systems. Technologies of cryptography like Group Key Based Attribute Encryption (GKBAE) and Modified Random Fibonacci Cryptography (MRFC) offers both data protection and reduced resource requirement in clouds. GKBAE enables fine-grained access control and attribute-based encryption that ensures high data security without any additional computation. In addition, the paper also talks about the privacy-preserving technology, and policy-oriented access control framework. Techniques like Linear Elliptical Curve Digital Signature (LECDS) that combine digital signatures with blockchain technologies can also be used to implement the above features. To sum up, the changing scenario of cloud security requires ceaseless innovation and application of the latest cryptographic methods. Through encryption, hardware level security features and distributed ledger technology implementation, data environment is more strengthened and vulnerabilities to hacking, data leakage, and unauthorized access are decreased. Making use of the modern security tools not only does the data safety but also is responsible for the trustworthiness and stability of the cloud computing infrastructure.
