Abstract

Cloud computing is one of the newest technologies in the era Cloud computing has become an extensively exploited research area in academic and industry. The security challenges related to cloud computing have been extensively studied. This review is aimed to highlight the existing research studies on cloud computing security, threats, and challenges and also proposed the security essentials for web-based applications. Cloud services are facing problems in providing security regarding data and file storage as well as sharing the files through cloud, securing the cloud from the threat actors causing external threats we are trying to address these issues to make reliable and secure file sharing and storage on cloud. We have developed file sharing system, security powered with AES encryption algorithm along with the Proxy Re-encryption (Proxy Transformation) to enhance the security on the cloud platform as well as while transferring the data.
