Secured Data Transfer For Cloud Using Blowfish
As an emerging technology and business paradigm, Cloud computing platforms provide easy access to a
company’s high-performance, computing and storage infrastructure through web services. Mainly cloud computing
technology enables users/enterprises to eliminate the requirements for setting up of expensive computing infrastructure and
reduces system’s operating costs. As a result, this technology is used by an increasing number of end users. On the other
hand, existing security deficiencies and vulnerabilities of underlying technologies can leave an open door for intrusions.
Therefore, cloud computing providers need to protect their user’s sensitive data from insider or outsider attacks by installing
an intrusion detection system. Form the viewpoint of security, various risks and issues are identified in the area of Cloud
Computing. There are various risks associated with the security but one of the major issues is the security of data being
stored on the provider's cloud and privacy while the data is being transmitted. This paper deals with various issues associated
with security and focus mainly on the data security and methods of providing security by data encryption. Various encryption
methods of block cipher algorithms such as RSA, Blowfish are discussed for providing solutions to cloud security.
