Secure Multi-tenant Design for Cloud Computing Environment

Abstract

Multi-tenancy is one of the most important elements of cloud computing environment due to salability and economic benefit it offers for both cloud service provider (CSP) and end user. As resources are shared, it induces security and privacy issues and tenant dependent on cloud service provider to assign trustworthy co-tenants. However, CSP maximize its resource utilization by allowing maximum co-tenancy irrespective of the behaviors of tenants. Subsequently techniques like Reputation management based design aid in identifying good and malicious tenants. However, the state-of-art model is not efficient when behavior of malicious tenant changes rapidly. Addressing the said research issue, a secure multi-tenant (SMT) design using a modified reputation management model is proposed which handles dynamic behavior of tenants efficiently for cloud computing environment. Experiments are conducted using TPCC benchmark shows significant performance in terms of latency and throughput by SMT over state-of-art model.
