Research and Implementation of Type-1-Based Virtualization Security System in Smart Devices Environment

Background: The mobile virtualization security system can provide enhanced security with separated environment of simultaneously and independently operating multiple OS on the Hypervisor Abstraction Layer. Methods Analysis: This paper introduces the research and implementation of Type-1-Based Virtualization Security System in Smart Device Environment. Its detailed functions are mobile virtualization management, security authentication, security policy and access control, encryption/decryption, and safe storage that provide secure communication among the guest Operating Systems. This paper also introduces an experimental product operating a mobile office application. Findings: In the comparative test with the existing TEEMO Type-2-based Virtualization Security System, it measured processing times of compulsory loading situation and no-loading situation for 12 major security APIs. As a result, our system has showed reduced API processing time from 48% to 85%, faster processing speed in both compulsory loading situation and noloading situation. Its average processing time has been 0.189 in the situation of consecutive API callings. Therefore, our system has proved acceptable processing time for real users as well as enhanced security with authentication and safe storage in the mobile hypervisor virtualization system. Application/Improvements: This research can offer assistance in providing secure communication and speed improvement among guest OS in mobile virtualization environment.
