In current mobile system environment there is a large gap in the use of smart phones for personal and enterprise use due to required enterprise security policies, privacy concerns as well as freedom of use. In the current environment, data-plans on mobile systems have become so wide spread that the rate of adaptation of data plans for every day customers has far outpaced the ability for enterprises to keep up with existing secure enterprise infrastructures. Most of the enterprises require/provide the access of emails and other official information on smart platforms which presents a big challenge for the enterprise in securing their systems. Therefore due to the security issues and policies imposed by the enterprise in using the same device for dual purpose (personal and enterprise), the consumers often lose their individual freedom and convenience at the cost of security. Few solutions have been successful addressing this challenge. One effective way is to partition the mobile device such that the enterprise system access and its information are completely separated from the personal information. Several approaches are described and presented for mobile virtualization that creates a secure and secluded environment for enterprise information while allowing the user to access their personal information. A reference architecture is then presented that allows for integration with existing enterprise mobile device management systems and at the same time providing a light weight solution for containerizing mobile applications. This solution is then benchmarked with several of the existing mobile virtualization solutions. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2013.

The Evolvable Virtual Machine abstract architecture (EVMA) is a computational architecture for dynamic hierarchically organised virtual machines. The concrete EVM instantiation (EVMI) builds on traditional stack-based models of computation and extends them by notions of hierarchy and reflection on the virtual machine level. The EVM Universe is composed of a number of autonomous and asynchronously communicating EVM machines. The main contribution of this work lies in the new model of computation and in the architecture itself: a novel, compact, flexible and expressive representation of distributed concurrent computation. The EVMA provides a way of expressing and modelling auto-catalytic networks composed of a hierarchical hypercycle of autopoietic subsystems characterised by self-adaptable structural tendencies and self-organised criticality. EVMA provides capabilities for: a) self-learning of dynamical patterns through continuous observation of computable environments, b) self-compacting and generalisation of existing program structures, c) emergence of efficient and robust communication code through appropriate machine assembly on both ends of communication channel. EVMA is in one sense a multi-dimensional generalisation of stack machine with the purpose of modelling concurrent asynchronous processing. EVMA approach can be also seen as a meta-evolutionary theory of evolution. The EVMA is designed to model systems that mimic living autonomous and adaptable computational processes. The EVMI prototype has been designed and developed to conduct experimental studies on complex evolving systems. The generality of our approach not only provides the means to experiment with complex hierarchical, computational and evolutionary systems, but it provides a useful model to evaluate, share and discuss the complex hierarchical systems in general. The EVMA provides a novel methodology and language to pursue research, to understand and to talk about evolution of complexity in living systems. In this thesis, we present the simple single-cell EVMI framework, discuss the multi-cell EVM Universe architecture, present experimental results, and propose further extensions, experimental studies, and possible hardware implementations of the EVMI.
