The framework for efficient passphrase-based multifactor authentication in cloud computing

Abstract

Cloud computing has quickly become one of the top innovations in the information technology world due to its benefits in terms of costs, flexibility, accessibility, availability, increased throughput and the ease of use. However, it faces major security issues and challenges that must be addressed and investigated. Due to its expansion on a very large scale, many potential users are facing threats of data protection and privacy. In this paper, we discuss the major authentication frameworks in cloud computing environment and provide analysis of different authentication models in cloud computing.
