TL;DR: The framework for end-to-end encrypted data aggregation has higher computation cost on the sensor nodes, but achieves stronger security, in comparison with the framework for hop-by-hopencrypted data aggregation.
Abstract: Data aggregation is a widely used technique in wireless sensor networks. The security issues, data confidentiality and integrity, in data aggregation become vital when the sensor network is deployed in a hostile environment. There has been many related work proposed to address these security issues. In this paper we survey these work and classify them into two cases: hop-by-hop encrypted data aggregation and end-to-end encrypted data aggregation. We also propose two general frameworks for the two cases respectively. The framework for end-to-end encrypted data aggregation has higher computation cost on the sensor nodes, but achieves stronger security, in comparison with the framework for hop-by-hop encrypted data aggregation.

TL;DR: An attribute-based access control model (WS-ABAC) is presented to address the issues of administrative scalability and control granularity in access control systems, and can provide administratively scalable alternative to identity-based authorization methods and provide fine-grained access control for Web services.
Abstract: Web service is a new service-oriented computing paradigm which poses the unique security challenges due to its inherent heterogeneity, multi-domain characteristic and highly dynamic nature. A key challenge in Web services security is the design of effective access control schemes. However, most current access control systems base authorization decisions on subject?s identity. Administrative scalability and control granularity are serious problems in those systems, and they are not fit for Web services environment. So an attribute-based access control model (WS-ABAC) is presented to address these issues in this paper. WS-ABAC grants access to services based on attributes of the related entities, and uses automated trust negotiation mechanism to address the disclosure issue of the sensitive attributes. It can provide administratively scalable alternative to identity-based authorization methods and provide fine-grained access control for Web services. Moreover, it also can protect user?s privacy.

TL;DR: This paper optimize LEACH’s random cluster-head selection algorithm to ensure the balanced energy depletion over the whole network thus prolongs the network lifetime and proposes an optimal energyadaptive clustering algorithm which is motivated from the LEACH protocol.
Abstract: A wireless network consisting of a large number of small sensors with limited battery power can be an effective tool for gathering data in a variety of environments. Clustering sensors into groups, so that sensors communicate information only to cluster-heads and then the cluster-heads communicate the aggregated information to the base station, may save energy. In this paper, we propose an optimal energyadaptive clustering algorithm which is motivated from the LEACH protocol presented in [4]. We optimize LEACH’s random cluster-head selection algorithm to ensure the balanced energy depletion over the whole network thus prolongs the network lifetime. Simulation results show that our algorithm outperforms LEACH by about 20% to 35% when 1%, 50%, 100% of nodes die for different network sizes and topologies.

TL;DR: A honeypot is a supplemented active defense system for network security that traps attacks, records intrusion information about tools and activities of the hacking process, and prevents attacks outbound the compromised system.
Abstract: A honeypot is a supplemented active defense system for network security. It traps attacks, records intrusion information about tools and activities of the hacking process, and prevents attacks outbound the compromised system. Integrated with other security solutions, a honeypot can solve many traditional dilemmas. We expatiate key components of data capture and data control in a honeypot, and give a classification for honeypots according to security goals and application goals. We review the technical progress and security contribution of production honeypots and research honeypots. We present typical honeypot solutions and predict the technical trends of integration, virtualization and distribution for future honeypots.

TL;DR: It is demonstrated that a prototype implementation of CheCUDA can correctly checkpoint and restart a CUDA application written with basic APIs and also indicates that Che CUDA can migrate a process from one PC to another even if the process uses a GPU.
Abstract: In this paper, a tool named CheCUDA is designed to checkpoint CUDA applications that use GPUs as accelerators. As existing checkpoint/restart implementations do not support checkpointing the GPU status, CheCUDA hooks a part of basic CUDA driver API calls in order to record the status changes on the main memory. At checkpointing, CheCUDA stores the status changes in a file after copying all necessary data in the video memory to the main memory and then disabling the CUDA runtime. At restarting, CheCUDA reads the file, re-initializes the CUDA runtime, and recovers the resources on GPUs so as to restart from the stored status. This paper demonstrates that a prototype implementation of CheCUDA can correctly checkpoint and restart a CUDA application written with basic APIs. This also indicates that CheCUDA can migrate a process from one PC to another even if the process uses a GPU. Accordingly, CheCUDA is useful not only to enhance the dependability of CUDA applications but also to enable dynamic task scheduling of CUDA applications required especially on heterogeneous GPU cluster systems. This paper also shows the timing overhead for checkpointing.
