Test Models and Coverage Criteria for Automatic Model-Based Test Generation with UML State Machines

Commonly Security models are used to determine how security will be implemented, what subjects can access the system, and what objects they will have access to. The Models are a way to formalize security policy. Security models of control are typically implemented by enforcing integrity, confidentiality, or other controls. The state machine defines the behavior of a finite number of states, the transitions between the states and actions which can occur. The Information Flow Model serves as the basis of design for both. Objects are part of the Information Flow Model. Also transitions and lattice states.

Skip to search form Skip to main content. Model-based functional testing is focussed on comparing the system under test to a test model. This comparison usually consists of automatically generating a test suite from the test model, executing the test suite, and comparing the observable behavior to the expected one. View Paper.

Abstract Identifying the finite state control structure of a black box system from the traces observed in finite interaction is of great interest for many model-based activities, such as model-based testing or model-driven engineering. There are several inference methods, but all those methods assume that the system can be reset whenever necessary. In this paper, we address the issue of inferring a finite state machine FSM that cannot be reset; we propose a method, inspired by FSM-based testing generation methods. We assume classical testing hypotheses, namely that we are given a bound n on the number of states and a set W of characterizing sequences to distinguish states. To the best of our knowledge, this is the first model inference method that does not require resetting the system, and does not require an external oracle to decide on equivalence. The length of the test sequence is polynomial in n and the exponent depends on the cardinal W of the characterization set.

We then propose, implement and evaluate a novel VMI framework that applies knowledge of the operating system and derived through a source code analysis to reconstruct the kernel state from physical memory. This work explores the possibilities and implications of bridging the semantic gap between the hypervisor and its virtual machines to support security applications using a technique called virtual machine introspection VMI.

Abstract In this chapter, we introduce a fundamental building block of custom hardware design: The datapath receives commands from the controller and performs operations as a result of executing those commands. The controller uses the results of datapath operations to make decisions and to steer control flow. Finally, we will also describe a few formal properties of the FSMD model, and we will define a proper FSMD as one which leads to a race-free and deterministic hardware implementation.

Security Model State Machine This chapter presents a detailed description and comprehensive discussion of the first known method for active IC metering and IC piracy prevention which allow uniquely locking each manufactured IC at First Time Seeing Nude Woman foundry. The locking structure is embedded during hardware synthesis by FSM modifications such that the IC would not be functional without a proper chips specific passkey that can only be computed by the designer IP rights owner. We show the analogy between the hardware synthesis transformations and program compilation, and pose the problem of extending the FSM for hiding the locks as an instance of the classic program obfuscation problem. We demonstrate a construction of the locks within FSM as an instance of a general output multi-point function family. This family is known to be effectively obfuscatable in the random oracle model.
