To deal with the problem of external storages management in multiple virtual machines environment, a system design scheme of external storages management is proposed with the idea of virtual memory management and protocol of object-based Network storage. Experiments showed that virtual partition could be created and repealed dynamic, the capability of partition could be increased dynamic with practical requirement, and write protection based partition could also be realized, flexibility of external storages management is enhanced greatly and usage efficiency also increased notably.

Secure Element

Purpose – The purpose of this paper is to address the design, implementation, performance and limitations of an environment that emulates a secure element for rapid prototyping and debugging. Today, it is difficult for developers to get access to a near field communication (NFC)-secure element in current smartphones. Moreover, the security constraints of smartcards make in-circuit emulation and debugging of applications impractical. Therefore, an environment that emulates a secure element brings significant advantages for developers. Design/methodology/approach – The authors' approach to such an environment is the emulation of Java Card applets on top of non-Java Card virtual machines (e.g. Android Dalvik VM), as this would facilitate the use of existing debugging tools. As the operation principle of the Java Card VM is based on persistent memory technology, the VM and applications running on top of it have a significantly different life cycle compared to other Java VMs. The authors evaluate these differences and their impact on Java VM-based Java Card emulation. They compare possible strategies to overcome the problems caused by these differences, propose a possible solution and create a prototypical implementation to verify the practical feasibility of such an emulation environment. Findings – While the authors found that the Java Card inbuilt persistent memory management is not available on other Java VMs, they present a strategy to model this persistence mechanism on other VMs to build a complete Java Card run-time environment on top of a non-Java Card VM. Their analysis of the performance degradation in a prototypical implementation caused by additional effort put into maintaining persistent application state revealed that the implementation of such an emulation environment is practically feasible. Originality/value – This paper addresses the problem of emulating a complete Java Card run-time environment on top of non-Java Card virtual machines which could open and significantly ease the development of NFC secure element applications.
