A Comprehensive Study on Cryptographic Approaches for Securing Data in Cloud Storage

Abstract: Cloud computing is entirely dependent on the internet. Cloud service providers (CSPs) such as Google, Amazon, Salesforce, Microsoft and others store and manage client data in their data centers. Maintaining and keeping an eye on the outsourced data is the responsibility of CSP. Data leakages insecure interfaces resource sharing data availability and inside attacks are just a few of the security problems and threats that can arise from having little control over the data. Security availability performance lack of standards higher usage costs and difficulty integrating with on- premise IT resources are the initial problems. Because they are unaware of where their data will be stored whether it will be available when they need it and whether it will be processed by others a large number of clients do not fully rely on the cloud environment. Cloud security is a significant issue that needs to be taken seriously because cloud users are more concerned with their data. Data security is a major cloud concern. Confidentiality integrity and availability are some of the factors that can help achieve data security. The study also looks at how hybrid frameworks and steganography can enhance authentication and secrecy in cloud environments. In order to improve the security of data while it is at rest a number of algorithms have been investigated.
