33024.第三章基于传感器的身体行为互动框架
[计算机、通信和其他电子设备制造业] [2013-12-29]
The grasp and the task are two actions closely related. A grasp is always performed with a purpose in mind, and the execution of a task requires a suitable task-oriented grasp in most of the cases. The grasp does not need to be prehensile. Most of our daily life manipulation is done trough non-prehensile grasps. Interaction with the environment is always preceded by a contact configuration, as a result of a prehensile or non-prehensile grasp. And vice versa, a contact configuration on one object is always followed by a desired motion according to the task: lift, push, etc.

33025.无线传感器网络入侵检测:问题,挑战和方法
[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2013-12-29]
Wireless sensor networks (WSNs) have generated immense interest among researches for the last few years motivated by several theoretical and practical challenges. The increase in interest is mainly attributed to new applications designed with large scale networks consisting of devices capable of performing computations on the sensed data and finally processing the data for transmitting to remote locations. Providing security to WSNs plays a major role as these networks are generally deployed in inaccessible terrain and also for their communication being in the wireless domain. These reasons impose security mechanisms to be employed on the highly vulnerable sensor networks that are robust enough to handle attacks from adversaries. WSNs consist of nodes having limited resources and therefore classical security measures applicable in traditional networks cannot be applied here. So the need of the hour is using systems that lie within the boundary of the sensor nodes resource potential as well competent enough to handle attacks. Intrusion detection is one such defense used in sensor networks having the ability to detect unknown attacks and finding means to thwart them. Researches have found intrusion detection system (IDS) to be very much compatible in sensor networks. Therefore intrusion detection holds a very prominent research area for researchers. So familiarity with this promising research field will surely benefit the researchers. Keeping this in mind we survey the major topics of intrusion detection in WSNs. The survey work presents topics such as the architectural models used in the different approaches for intrusion detection, different intrusion detection techniques and highlights intrusion detection methods applicable for the different layers in sensor networks. The earlier achievements in intrusion detection in WSNs are also summarized along with more recent works and existing problems are discussed. We also give an insight into the possible directions for future work in intrusion detection involving different aspects in sensor networks.

33027.一种改进的前向安全的椭圆曲线签名加密的无线传感器网络密钥管理方案
[计算机、通信和其他电子设备制造业,信息传输、软件和信息技术服务业] [2013-12-29]
The concept of forward secrecy is extended to wireless sensor networks where it is frequent that nodes run out of energy and new nodes join the network. However it should not be able to retrieve the previous session key or some crucial information. In 2011 Hagras et al. proposed a key management scheme for heterogeneous wireless sensor networks, which satisfies confidentiality, authentication, integrity and unforgetability but lacks forward secrecy. In this paper, the shortcomings of the victim scheme has been extricated and repaired with the help of Elliptic Curve Discrete logarithm problem (ECDLP). An elliptic curve based signcryption key management scheme has been proposed which includes forward secrecy.

33029.通过保护传感器节点的反侧信道攻击提高无线传感器网络的安全
[计算机、通信和其他电子设备制造业] [2013-12-29]
The intent of this chapter is to introduce side channel attacks as a significant threat for wireless sensor networks, since in such systems the individual sensor node can be accessed physically and analysed afterwards. Even though such attacks are known for some years, they have never been specifically considered before in the area of WSNs (Wireless Sensor Networks).

33030.一种旨在提升基于集团的无线传感器网络安全性和性能的安全的集团内时间同步技术
[信息传输、软件和信息技术服务业,计算机、通信和其他电子设备制造业] [2013-12-29]
Time synchronization is required in wireless sensor networks in order to improve its performance. This improvement could be noticed in terms of energy, storage, computation, shared resources or bandwidth. One of the main applications in WSNs has been to decrease the energy consumption. A wireless network can save energy with this feature, but if this synchronization is corrupted, it could cause a worse behavior. Firstly, we will analyze which are the most important time synchronization issues. Then, a secure time synchronization method will be presented for group-based wireless sensor networks to avoid malicious attacks. The synchronization technique is based on a system model for secure intra-group synchronization. This system will use simple messages, where nodes of each group will exchange several parameters like time stamps, groupID, etc. in order to make a secure system. The system proposed has high scalability, due to group-based feature, while saves energy thanks to the designed synchronization technique. In order to test our proposal we will simulate several situations to show the performance of our synchronization algorithm.
