Adaptively secure key-policy ABE scheme with fast decryption

In the existing adaptively secure ABE (attribute-based encryption) schemes, the decryption cost goes linearly with the number of attributes that are used in decryption. An adaptively secure key-policy ABE (FKP-ABE) scheme with fast decryption is proposed, where constant size of computation overhead is implemented in decryption. This scheme is constructed on composite order bilinear groups and supports any monotonic access structure that can be expressed by LSSS (linear secret sharing schemes). The proposed scheme is proved to be adaptively secure in the standard model. ©, 2014, Editorial Board of Journal on Communications. All right reserved.

In this paper, we have introduced a cross-layer design model which is based on multimedia services in order to favor the QoS demand in wireless mesh networks. By means of this model the relevant parameters in each layer of the whole network protocol stacks have been considered. Parameters Link consumption and packet error rate in the wireless transmission have been optimal controlled to enhance the throughput of wireless and optimize the overall performance of wireless mesh network. The experimental results show that compared with the general model, the average throughput of the multimedia transmission has increased more than 35% based on the cross-layer model proposed in this paper. Consequently the overall performance of the network has been optimized. © 2013 by Binary Information Press.

With the rapid development of online learning, users have more and more diverse ways to learning. The advantage of online learning is that the e-learners' behaviors can be completely recorded in the log events. So learning analytics can be made on these data. More than 500 freshmen used Moodle to study our "C program" course each year. So a large number of learning data have been collected. How to make analysis of the data is very meaningful. In this paper, we focused on analyzing characteristics both the learning behaviors and the nonintellectual factor of e-learners, such as emotion. We aimed to find the main factors which influence learner's achievements. These factors might be submit time of programs, login times, the frequency of assignment view, etc. Based on the analysis, we adopted The Positive and Negative Affect Scale (PANAS) and Felder & Solomon Learning Styles and Strategies surveys to obtain e-learner's emotion and learning style in a certain period of time or currently. Then we made the correlation analysis between e-learner's emotion, learning style and their achievements. The experimental results made a verification that positive emotion has a great influence on the user. And also the learning enthusiasm of visual learners is obviously higher than that of verbal learners.

This paper presents an unsupervised random walk approach to alleviate data sparsity for selectional preferences. Based on the measure of preferences between predicates and arguments, the model aggregates all the transitions from a given predicate to its nearby predicates, and propagates their argument preferences as the given predicate's smoothed preferences. Experimental results show that this approach outperforms several state-of-the-art methods on the pseudo-disambiguation task, and it better correlates with human plausibility judgements. © 2013 Association for Computational Linguistics.

Detecting GPS information leakage in Android applications

Detecting GPS information leakage in Android applications

Location Based Service(LBS) becomes very popular in mobile computing platforms, such as Android. However, it could also leak highly personal information about the phone owner if used by Malwares. It has been witnessed that an increased number of malicious Android applications use LBS to obtain users' locations and transmit them to attackers without users' acknowledgement, causing users' privacy breach. In this paper, we first discuss the common way in which privacy can be breached in Android applications, and then define a classification algorithm for GPS information leakage. Furthermore, we develop a location information leakage detection tool named Brox. Brox is based on dalvik-opcode specification, which uses data flow analysis framework equipped with flow-sensitive, context-sensitive, and inter-procedure techniques to detect potential information leakage path in Android malicious applications. Specifically, Brox uses inter-procedure analysis and dependency calculation to understand the intention for each sensitive operation;by using reachable analysis, connection between privacy access operation and leakage operation is established. More importantly, Brox confirms whether the sending out operation contains location information or not using static taint analysis. At last, we classify the detection results with the help of identification of interaction and non-user interaction entry points in order to discover stealthy leaks of GPS location. The extensive experiments results show that the proposed method can effectively detect privacy leakage in Android applications with a high accuracy rate. © 2013 IEEE.

A Role Based Privacy-Aware Secure Routing Protocol for Wireless Mesh networks

Wireless Personal Communications 2013年第3期75卷 1611-1633页

Wireless Mesh networks (WMNs) have drawn much attention for emerging as a promising technology to meet the challenges in next generation networks. security and privacy protection have been the primary concerns in pushing towards the success of WMNs. There have been a multitude of solutions proposed to ensure the security of the routing protocol and the privacy information in WMNs. However, most of them are based on the assumptions that all nodes cooperate with routing and forwarding packets and the attacks are from outside. In order to defend against the internal attacks and to achieve better security and privacy protection, this paper proposes a role based privacy-aware secure routing protocol (RPASRP), which combines a new dynamic reputation mechanism with the role based multi-level security technology and a hierarchical key management protocol. Simulation results show that RPASRP implements the security and privacy protection against the inside attacks more effectively and efficiently and performs better than the classical hybrid wireless mesh protocol in terms of packet delivery ratio and average route length.

Signcryption is a cryptographic primitive that performs digital signature and public key encryption simultaneously, at lower computational costs and communication overhead than signing and encrypting separately. Recently, Chung et al. proposed an anonymous ECC-based signcryption scheme. We show that their scheme is not secure even against a chosen-plaintext attack.

To begin with, this paper introduces a topic map oriented e-learning platform - Yotta. We compare the Yotta with the traditional e-learning platform Moodle from the aspects of learning resources organization, design of learning activities, learning behavior characteristics of learners, etc. Secondly, we provide two new criteria which can reflect e-learners' learning behavior using topic maps: the coverage of knowledge elements clicked by e-learners on topic maps (F);the length of time from loginning Yotta to clicking on the first useful knowledge element (T). Finally, we analyze the changes of e-learners' learning behavior and the learning efficiency on these two different e-learning platforms. The testees in the experiment are twenty-eight students learning the course of "computer network". The experimental results show that the features as learning positivity and learning time of e-learners do not change with the type of network platforms. This discovery can further provide the nodes of our personalized recommendation to e-learners.
