Topic: "Secure virtual machine placement for IaaS clouds" supervised by Dr.Ta Nguyen Binh Duong

  • Designed a new virtual machine placement algorithm which combats side-channel attacks in public IaaS cloud data centers by reducing the probability of an adversary to co-locate their Virtual Machine(VM) with a benign user during initial VM placement.

  • Performed a theoretical and empirical analysis of the proposed algorithm to evaluate its resource efficiency and security. Results obtained using real-world Microsoft Azure workload dataset indicated that the proposed algorithm provides a significant increase in the cloud's co-location resistance with little compromise in resource utilization, compared to existing approaches.
