Shared data security is a major worry in today’s world. An individual uses the data-sharing system to upload a file that has been encrypted with the private key. This feature is essential in any system for sharing huge amounts of data since it makes it hard for the owner of the data to maintain the secrecy of the information if one of the users discloses the important information. It provides a concrete and effective implementation of the strategy, showing its viability and establishing the security of the method. Data owners encounter a variety of challenges when it comes to sharing their data on servers or in the cloud. These problems have a number of solutions. These techniques are essential for handling keys that the data owner has shared. The purpose of the paper is to establish trusted authority for user authentication when accessing cloud data. A trustworthy authority generates the key using the SHA algorithm, which is subsequently sent to both the user and the owner. After receiving an AES-encrypted file from the data owner, the trusted authority module computes the hash value using the MD-5 method. Its database contains keys that will be used to detect during dynamic operations which user is abusing the system. The file is sent from a trustworthy source to the CSP module, which saves it in the cloud. It is demonstrated that the produced key sets have a variety of desired qualities that protect communication session confidentiality from collusion assaults by other network nodes. The proposed model provides a flexible and scalable approach to access control, as it allows administrators to define different trust levels and policies for different cloud resources. This model also includes mechanisms for monitoring user behavior and detecting anomalies that may indicate a breach of trust. The access control model offers an effective solution for securing cloud computing environments while ensuring that users can access the resources, they need to perform their tasks.
