Securing Authentication and Trusted Migration of Weblets in the Cloud with Reduced Traffic

Cloud computing is making a new revolution in the computing world. Elasticity is one of the key features of the cloud which makes cloud computing further fashionable. Cloud is still in its infant stages and it faces a wide range of security threats. The security downtime of cloud is relatively slowing down the spreading up of cloud computing. This paper focuses on the security threats faced by the web lets during their migration between the cloud and the mobile devices. Web let migration is an important task during the implementation of elasticity in the cloud. As a primary step, a secure communication channel is designed for the web let migration by deploying secure shell protocol. Herein, the vulnerabilities in some authentication mechanisms are highlighted and a better way of authenticating the web lets with SFTP (Secure File Transfer Protocol) is suggested. Finally, managing the traffic effectively in the designed channel with the aid of back pressure technique is also covered in this paper.
