Analysis of Multilevel Security based Service Access Control and Data Protection Approach for Cloud

Abstract

Resolving security issues in cloud-based systems has been a focused area for research from quite some time. Many techniques and models have been proposed by researchers but still there is a scope for improvement in this regard. Issues like access control and authentication for accessing services has been a prime area of concern over the years. Over a cloud using or accessing various services securely is a major concern keeping in mind the malicious insider attack which might occur raising security concerns for Cloud Service Providers(CSP’s). Apart from this, data security with a suitable mechanism for key exchange over cloud has also been a major concern for cloud practitioners. Here in this paper one such technique for service access key distribution acting as multilevel security technique, being made securely has been discussed and analyzed. System implementation is performed on a system modelled as cloud using a simulation tool CloudSim. The paper also covers implementation and analysis of a secure technique for data protection over cloud using digital signature and cryptography.
