EncryScation: A novel framework for cloud IaaS, DaaS security using encryption and Obfuscation techniques

摘要

Now a days every industry needs more income with less investment behind infrastructure. Here, the new era of Cloud computing comes where the user can have everything on rent and "pay as go" fundamental. Cloud users are able to store their valuable data on Cloud premises and make themselves free from local burden. While users data is available on Cloud servers, it is very important for the user that data must be secure when it is in transition and even after it has been stored on server. Most of the researchers think for the user centric(side) scenario i.e mainly consider the security issue related to Cloud users like Integrity checking, Authentication, Versioning Etc. On the other hand, some researchers provide their view related to working of Cloud service providers i.e. Database encryption, Security based on Metadata, Data Obfuscation Etc. To have proper confidentiality, Security and integrity of data, this paper presents two techniques, that is: Encryption, authentication at client side as well as Data Obfuscation at server side. Encryption helps user to provide secrecy to its data when it is transferred in the network. Data obfuscation helps service provider to secure the users data on his premises. By applying these two techniques, the user and Service provider gets maximum protection against intruders and unauthorized access.
