Secure and Efficient Authentication System for Cloud using Improved Hybrid Encryption Standard

Cloud computing (CC) is a virtualization technique that allows users to build and customise applications that run on the internet. Cloud technology is made up of a digital competence, a hard disc, a package application, and information. A trustworthy and dependable cloud storage service will be a great alternative for keeping data on the internet while being secure and stress-free. If security requirements are properly managed, many enterprises and government organisations will transit to cloud environments. The server for cloud storage systems, on the other hand, contains a significant amount of data. Data confidentiality is lost because data is kept for an extended length of time over the internet, allowing hackers to steal data from the storage system. Even when data is moved to the cloud, it retains data integrity (DI), which frequently disappoints cloud consumers. This article discusses about existing authentication and encryption systems in terms of user scenarios, distinguishing features, and limits. This research also looks at the benefits and drawbacks of authentication and data encryption strategies for CC services..
