This paper describes the design and implementation of the T=1 protocol based on lava Card. The T=1 protocol implemented in this paper complies with ISO/IEC 7816 standard. Also, JCOS(Java Card Operating Systems) including the contactless card protocol conforms to Java Card 2.2.1 specification and is running on 32-bit ARM7/TDMI processor. The protocol stack proposed and implemented in this paper is easy to maintenance of protocol independently. To verify the T=1 protocol implemented in this paper we tested the T=1 protocol scenarios defined in ISO/IEC 7816-3 Annex A. And we tested using USIM(Universal Subscriber Identity Module) cards, which include the implemented T=1 protocol. The T=1 protocol was tested and passed all against the specification 3GPP TS 31.122, which was the Conformance Test Specification for USIM cards including the test suites of both transmission protocols.

In general, test data generation techniques require the specification of an entire program path for automated test data generation. This paper presents a new way for generating test data automatically een without specifying a program path completely. For the ends, this paper presents a technique for transforming a program under test into Alloy which is the first order relational logic and then producing test data via Alloy analyzer. The proposed method reduces the burden of selecting a program path and also makes it easy to generate test data according to various test adequacy criteria. This paper illustrates the proposed method through simple, but illustrative examples.

Weapon systems composed of several subsystems execute various engagement missions in distributed combat environments in cooperation with a large number of subordinate/adjacent weapon systems as well as higher echelons through tactical data links. Such distributed weapon systems require distributed real-time simulation test beds to integrate and test their operational software, analyze their performance and effects of cooperated engagement, and validate their requirement specifications. These demands present significant challenges in terms of real-time constraints, time synchronization, complexity and development cost of an engagement simulation test bed, thus necessitate the use of high-performance distributed real-time simulation architectures, and modeling and simulation techniques. In this paper, in order to meet these demands, we presented a distributed real-time simulation system based on High Level Architecture(HLA) and Discrete Event System Specification(DEVS). We validated its performance by using it as a test bed for developing the Engagement Control System(ECS) of a surface-to-air missile system. The proposed technique can be employed to design a prototype or model of engagement-level distributed real-time simulation systems.

The communication-based train control (CBTC) technology is a kind of railway signaling technologies and is to control the train operation through communication. A project adopting the CBTC technology is in progress and its object is to develop interoperable and interchangeable subsystems. Thus the purpose of this paper is on how to develop the required subsystems and integrate them successfully without sufficient design information at the system level. Accordingly this project shall require the integration and test at the system level. In order to do so, a top-level system specification shall be needed, which is not available in the current phase of the project. The main objective of the test and evaluation activities is to see whether the developed system meets the system specification. In this paper, we describe how the test and evaluation can be carried out based on the subsystems design specifications, considering the system architecture and the operation concept of the existing system as well.

This paper proposes a test method for compliance of SMS encoder and decoder modules with 3GPP (3rd Generation Partnership Project) specification on SMS PDU (Protocol Data Unit). The existing tools have focused on providing an SMS gateway and on helping to view and edit a single SMS PDU, which rarely help to resolve the compliance test problem. The proposed compliance test method is based on an automatic generation of SMS PDUs fully compliant with the 3GPP specification by using QuickCheck library written in Haskell. By applying the proposed method to a C-based SMS encoder and decoder in Linux Mobile platform, we have found out several critical bugs such as wrong interpretation of time stamps in BCD format. The automatic SMS PDU generator is reusable in that it only depends on the 3GPP SMS specification. The QuickCheck library is also applicable for testing other network protocol data encoders and decoders, as used in this paper.

Timing diagram is a useful tool for describing the specification of system, but there is no study for test case strategy of a timing diagram. To solve this problem, we followed the steps to generate test cases from timing diagram in this paper. 1) We defined a timing diagram formally. 2) We describe the method of transforming from a timing diagram model into a Stateflow model which has an equivalent relationship between a timing diagram model and a transformed Stateflow model. 3) We generated test cases from a transformed Stateflow model using SDV which is plugged in Simulink. To show that our approach is useful, we made an experiment with a surveillance model and arbitrary timing diagram models. In the experiment we transformed timing diagram models into Stateflow models, generated test cases from transformed Stateflow models using SDV, and analyzed the generation results. The conclusion that can be obtained from this study is that timing diagram is not only a specification tool but also a useful tool when users are trying to generate test cases based on model.

In this paper, we study validation test methods of DEVSA(Descrete Event system Specification) models using SPN(Stochastic Petri Net) models. We discuss conventional validation test methods, by which DEVS models can be transformed to SPN models, by reviewing the features of DEVS model. Based on the model transformation method, we define a new homogeneous function for validation test and suggest a new validation test method of DEVS models using the property of SPN models and the new homogeneous function.
