“Security-as-a-Service” for files in cloud computing — A novel application model

Cloud Computing gains more popularity in current era, as it offers on-demand services. Numerous services are delivering upon the user request to make their process easier and more rapidly. It is necessary to secure the services which contain huge volume of data, while centralizing into cloud data centers for outsourcing. Challenge or the issue of each cloud service application lies in the confidentiality, availability and scalability in the data centers. In this paper, a new Security-as-a-Service based application model is proposed that offers encryption as a service to its consigners for assorted type of files. The proposed innovative application in public cloud model serves better to encrypt files consists of sensitive data and the result demonstrates efficiency of the application. Security analysis is performed for the proposed encryption algorithm that resist against various cryptanalytic attacks Comparative Analysis shows evidence of the efficacy of proposed pioneering application model.
