Research and Implementation of IP - VPN

Li Xiuzhong

Strategic Study of CAE 2002, Volume 4, Issue 3,   Pages 84-91

Abstract:

Recently, IP - VPN is proposed as a way satisfying large company´s inter-connect requirement because of the prevalence of Internet. But there are some problems to be solved, especially security and QoS. In this paper, one way of network-based VPN QoS is proposed based on analysis of some available QoS algorithms. For IP - VPN, now there are several mechanisms： VLL, VPRN, VPLS and VPDN. This paper places emphasis on VPRN and VPLS. Two kinds of VPRN: BGP/MPLS and VR are discussed and compared with each other. And besides, VLAN, one way of VPLS, is introduced.

Driftor: mitigating cloud-based side-channel attacks by switching and migrating multi-executor virtual machines Regular Papers

Chao YANG, Yun-fei GUO, Hong-chao HU, Ya-wen WANG, Qing TONG, Ling-shu LI

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 5,   Pages 731-748 doi: 10.1631/FITEE.1800526

Abstract:

Co-residency of different tenants’ virtual machines (VMs) in cloud provides a good chance for side-channel attacks, which results in information leakage. However, most of current defense suffers from the generality or compatibility problem, thus failing in immediate real-world deployment. VM migration, an inherit mechanism of cloud systems, envisions a promising countermeasure, which limits co-residency by moving VMs between servers. Therefore, we first set up a unified practical adversary model, where the attacker focuses on effective side channels. Then we propose Driftor, a new cloud system that contains VMs of a multi-executor structure where only one executor is active to provide service through a proxy, thus reducing possible information leakage. Active state is periodically switched between executors to simulate defensive effect of VM migration. To enhance the defense, real VM migration is enabled at the same time. Instead of solving the migration satisfiability problem with intractable CIRCUIT-SAT, a greedy-like heuristic algorithm is proposed to search for a viable solution by gradually expanding an initial has-to-migrate set of VMs. Experimental results show that Driftor can not only defend against practical fast side-channel attack, but also bring about reasonable impacts on real-world cloud applications.
