Light Weight Encryption Technique for Group Communication in Cloud Computing Environment

Cloud computing is a typical example of distributed computing and emerged as a new paradigm that moves computing and data away from desktop and portable PCs into large data centers. Cloud services have three broad categories based on the fundamental nature of the cloud-based solution they provide: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), or Software-as-a-Service (SaaS). In this paper, the authors have focused on the SaaS services provided by the Cloud Service Providers (CSP). The issue with SaaS is data security and confidentiality that makes the cloud user reluctant towards the cloud services. Data confidentiality can be achieved by encrypted outsourced content before outsourcing to cloud servers.
