At CRYPTO'19, Gohr[1] presented ResNet-based neural distinguishers (ND) for the round-reduced SPECK32/64 cipher. However, due to the black-box use of such deep learning models, it is hard for humans to understand why these distinguishers work, impeding advancements in cryptanalytic knowledge. In this work, we aim to effectively adapt eXplainable Artificial Intelligence (XAI) techniques, notably Local Interpretable Model-Agnostic Explanations (LIME) and Shapley Additive Explanations (SHAP), to gain a detailed understanding of the important features useful in Gohr's neural distinguishers.

Implementation of a kernel-level consistency control mechanism called invocation-based consistency control (IBCC) is presented. IBCC supports general-purpose persistent object-based distributed computing. It provides mechanisms that support a range of powerful, well-defined consistency semantics. IBCC mechanisms can also be used to implement custom recovery and synchronization. An operating-system-level implementation of IBCC as part of the Clouds distributed operating system that uses memory faulting to initiate locking and intermediate version creation is also given. Performance aspects are discussed, as well as the overhead incurred by supporting IBCC in terms of additional data structures needed in the operating system, and the additional amount of required code.< >

Journal of Information Hiding and Multimedia Signal Processing 2014年第1期5卷 20-32页

During the last years, a large number of information in digital form has been exchanged all over the world. Several techniques have been developed in order to protect the users' privacy of digital content. Steganography is one of them. Its use dates back for many centuries, yet it has been used profoundly in the last decades, as the proper mathematical background has been developed along with the need of the music and film industries. One aspect of this development is the use of DRM (Digital Right Management) as the main method of protecting digital assets. This work presents two new detection methods of steganographic content through the use of compressive sensing. The first method is a probabilistic filter that can increase the probability of detecting steganographic content in images, in case where the LSB method is used. The second one helps identifying the original from stego images when DCT steganography is used, after applying a filter with compressive sensing technique. © 2014.

Despite the recent progress in speech emotion recognition (SER), state-of-the-art systems are unable to achieve improved performance in cross-language settings. In this paper, we propose a Multimodal Dual Attention Transformer (MDAT) model to improve cross-language SER. Our model utilises pretrained models for multimodal feature extraction and is equipped with a dual attention mechanism including graph attention and co-attention to capture complex dependencies across different modalities and achieve improved cross-language SER results using minimal target language data. In addition, our model also exploits a transformer encoder layer for high-level feature representation to improve emotion classification accuracy. In this way, MDAT performs refinement of feature representation at various stages and provides emotional salient features to the classification layer. This novel approach also ensures the preservation of modality-specific emotional information while enhancing cross-modality and cross-language interactions. We assess our model's performance on four publicly available SER datasets and establish its superior effectiveness compared to recent approaches and baseline models. Copyright © 2023, The Authors.

International Conference on parallel and distributed systems (ICPADS)

作者： Mustafizur Rahman Rajiv Ranjan Rajkumar Buyya Cloud Computing and Distributed Systems Laboratory Department of Computer Science and Software Engineering University of Melbourne Australia Service Oriented Computing Research Group School of Computer Science and Engineering University of New South Wales Australia

In this paper, we propose a taxonomy that characterizes and classifies different components of autonomic application management in Grids. We also survey several representative Grid systems developed by various projects world-wide to demonstrate the comprehensiveness of the taxonomy. The taxonomy not only highlights the similarities and differences of state-of-the-art technologies utilized in autonomic application management from the perspective of Grid computing, but also identifies the areas that require further research initiatives.

Models and aspects-handling crosscutting concerns in MDSD: report on the workshop MA'07 at ECOOP 2007 07

This report summarizes the presentations and discussions of the ThirdWorkshop on Models and Aspects Handling Crosscutting Concerns in MDSD, held in conjunction with the 21st European Conference on Object-Oriented Programming (ECOOP) in Berlin, Germany on July, 31, 2007. This workshop was motivated by the fact that both Model-Driven Software Development (MDSD) and Aspect-Oriented Software Development (AOSD) are important new paradigms that both promise to change the way software is developed. Both approaches provide opportunities for concern separation. AOSD separates concerns horizontally and MDSD enables concern separation vertically. This workshop identified two key integration strategies to achieve the complementary benefits of both aspect-oriented and model-driven development. The first is the use of aspects within transformation languages to separate transformational concerns making model transformations easier to write. The second is the separation of concerns within models defined as aspects. This workshop established the key benefits of these. The major benefit of the first is easing the complexity of development and maintainability of transformations. The major benefit of the second is means to reduce the problems associated with aspects, such as, aspect interactions, fragile pointcuts and understandability.

As strong as possible mobility

As strong as possible mobility

In Java there is no close coupling between a thread and the objects from which they were created. The use of a container abstraction allows us to group threads and their respective objects into a single structure. A container that holds threads whose variables are all housed within the container is a perfect candidate for strong migration. To achieve this we propose a combination of three techniques to allow the containers to migrate in a manner that approaches strong mobility yet does not resort to retaining bindings to resources across distant and unreliable networks.

In this paper we present a negotiation agent based on Genetic Algorithm (GA) and Surrogate Modelling for a multi-player multi-issue negotiation model under incomplete information scenarios to solve a resource-allocation problem. We consider a multi-lateral negotiation protocol by which agents make offers sequentially in consecutive rounds until the deadline is reached. Agents' offers represent suggestions about how to divide the available resources among all agents participating in the negotiation. Each agent may “Accept” or “Reject” the offers made by its opponents through selecting the “Accept” or “Reject” option. The GA is used to explore the space of offers and surrogates used to model the behaviours of individual opponent agents for enhanced genetic evolution of offers that is agreeable upon all agents. The GA population comprises of solution individuals that are formulated as matrices where a specialised three different search operators that take the matrix representation into considerations are considered. Experimental studies of the proposed negotiation agent under different scenarios demonstrated that the negotiations by the agents completed in agreement before the deadline is reached, while at the same time, maximising profits.

Efficient scheduling is a key concern for the effectual execution of performance driven Grid applications, such as workflows. Many list heuristics have been developed for scheduling workflows in centralized Grid environment. However, in this paper, we present a distributed list heuristic for decentralized scheduling of workflow applications in global Grids. The simulation results show that the proposed scheduling approach is scalable with respect to increased workload on the system.

Dependable workflow scheduling in global Grids

Dependable workflow scheduling in global Grids

International Workshop on Grid Computing

In this paper, a reputation-based Grid workflow scheduling algorithm is proposed to counter the effect of inherent unreliability and temporal characteristics of computing resources in large scale, decentralized Grid overlays. The proposed approach builds upon structured peer-to-peer indexing and overlay networking techniques to create a scalable wide-area networking of Grid sites for supporting dependable scheduling of applications. The scheduling algorithm considers reliability of a Grid resource as a statistical property, which is globally computed in the decentralized Grid overlay based on dynamic feedbacks or reputation scores assigned by individual service consumers (Grid Resource Brokers). The proposed algorithm can dynamically adapt to changing resource conditions and offer significant performance gains as compared to traditional approaches in the event of unsuccessful job execution or resource failure. We evaluate and demonstrate the feasibility of our approach through an extensive trace driven simulation. The results show that our scheduling technique can reduce the makespan up to 50% and successfully isolate the failure-prone resources from the system.
