“…For example, when an embedded device detects sensor failure and mechanical failure simultaneously, the layer that needs to be activated preferentially is expected to be the layer that solves the mechanical failure. A C #-based COP framework known as ContextCS [12] was proposed in previous research. This framework uses the Observer Aspect [14] to manage the context according to priority, and a controller to manage the layer activation order.…”

In recent years, with the development of embedded software, the demand for context-aware software and the need for Context-Oriented Programming (COP) frameworks is increasing. In general, within the COP framework, each method is managed in units of layers, and time is required to activate the layers following context changes. Compared to the traditional singlethread method, the use of multi-threading to control the layer activation doubles the system efficiency. Moreover, embedded software usually includes mechanisms for exception handling, such as communication disconnection, mechanical or hardware failures, and insufficient energy. These mechanisms are expected to be types of high-priority operations, which also require multithreading to achieve preemptive layer activation. In this study, we propose an architecture for preemptive layer activation known as PLAM by using multi-threading, which is based on the RTCOP framework. Using PLAM, the non-exception handling layers can be activated simultaneously, and when the context of the exception handling layer is perceived, the program can call a certain function to suspend or terminate the activation process of the other layers. Finally, we package a series of functions as APIs so that users can use these to customize the context listener. A test application confirms the feasibility of the proposed approach.

“…Additionally, the use of aspects in C++ programs can help identify performance bottlenecks and optimize system resources. This study discusses the manual testing of embedded C++ programs in OS, focusing on memory utilization, program robustness, coverage, and program performance in C++, similar to previous research on OS testing [17]. Aspects are implemented in the context of kernel testing.…”

Cryptographic devices’ complexity necessitates fast security simulation environments against fault attacks. SystemC, a promising candidate in Electronic System Levels (ESLs), can achieve higher simulation speeds while maintaining accuracy and reliability, and its modular and hierarchical design allows for efficient modeling of complex cryptographic algorithms and protocols. However, code modification is required for fault injection and detection. Aspect-Oriented Programming (AOP) can test cryptographic models’ robustness without modifications, potentially replacing real cryptanalysis schemes and reducing the time and effort required for fault injection and detection. Through the utilization of a fault injection/detection environment, this paper presents a novel approach to simulating the security fault attacks of ASCON cryptographic systems at the ESL. The purpose of this methodology is to evaluate the resistance of ASCON SystemC models against fault attacks. The proposed methodology leverages the advantages of AOP to enhance the fault injection and detection process. By applying AOP techniques, we inject faults into the SystemC models without making any changes to the main codebase. This approach not only improves the efficiency of testing cryptographic systems but also ensures that the main functionality remains intact during the fault injection process. The methodology was validated using three scenarios and SystemC ASCON as a case study. The first simulation involved evaluating fault detection capabilities, the second focused on the impact of AOP on executable file size and simulation time, and the third focused on the ESL impact on the ASCON design process. Simulation results show that this methodology can perfectly evaluate the robustness of the ASCON design against fault injection attacks with no significant impact on simulation time and file executable size. Additionally, the simulation results prove that the ASCON development life cycle at the ESL reduces the amount of time devoted to the design procedure by 83.34%, and the ASCON security attack simulations at the ESL decrease the simulation time by 40% compared to the register transfer level (RTL).

“…Each layer contains the contextual information that would be playing important role for applications and services ranging from location-based situation dependent or even deeply personalized [1]. A number of languages and mechanisms have been proposed [2,3,4,5,6,7,8]; among them, we need to select appropriate mechanisms and extend to implement for satisfying the requirements of our robotics application.…”

Next generation robot is expected to provide multi-purpose services depending on surrounding environments. Currently, many of robots would support a limited services, since it is difficult to solve the cross-cutting concerns in those complex services. Additionally, after the launch of robot products, it requires to support additional extended services that would depend on the real environment, even if the hardware environment would be the same. We believe that the essential idea of Contextoriented programming (COP) could help these difficulties. To achieve our final goal, which is to develop a multi-purpose services robot, there are some discussions needed for the current COP languages to satisfy the multi-purpose service robot requirements. In this paper, firstly we introduce the background of our proposal that the current robotics problems and future vision, then a case study of a tunnel rescue robot that will make clear to our goal for robot development based on COP. Finally, to achieve this goal we present a novel architecture. The proposed architecture will satisfy the requirements of the future robot.
