Abstract: Impulse Radio Ultra Wideband is a new efficient short range wireless communication technology for wireless sensor network applications. Its impulsional nature makes it robust to multipath fading, as the short duration of the pulses leads most multipath components to arrive isolated with short energy pulses instead of a carrier signal. For a good exploitation of this new technology, we need a suitable Medium Access Control protocol in the MAC layer. WideMac was the first MAC protocol trying to implement adaptive low power consumption to IR-UWB technology. The Backoff algorithm used by this protocol is Modified Binary Exponent Backoff (MBEB). The …unfair access to the transmission channel represents the major problem of this algorithm. In this paper, we introduce a new Backoff algorithm based on Fuzzy Logic called FLB (Fuzzy Logic Backoff) to improve the Packet Delivery Ratio (PDR) and decrease the number of dropped packets from the nodes’ buffer. To analyze and evaluate the performance of the proposed backoff algorithm, a simulation of a sink based architecture network with various nodes’ number has been performed. Show more

Abstract: Wireless Sensor and Actor Network (WSAN) is formed by the collaboration of micro-sensor and actor nodes. Whenever there is any special event i.e., fire, earthquake, flood or enemy attack in the network, sensor nodes have responsibility to sense it and send information towards an actor node. The actor node is responsible to take prompt decision and react accordingly. In this work, we consider the actor node selection problem and implement two intelligent fuzzy-based systems (IFBSs). We call these systems IFBS1 and IFBS2. For IFBS1, we consider three input parameters: Job Type (JT), Distance to Event (DE) and Remaining Energy (RE). …In IFBS2, we add CS parameter, so IFBS2 has four input parameters. The IFBS2 is more complex than IFBS1, but can make a better selection of actor nodes than IFBS1 by considering also the actor congestion situation. Show more

Abstract: Searchable symmetric encryption (SSE) allows a data owner to outsource his encrypted data to a cloud server while retaining the ability to perform keyword search over encrypted data. The security guarantees of existing SSE schemes require that the adversary has no access to the data owner’s secret keys. Unfortunately, adversaries may get some or all of the secret keys through memory attacks. Facing such memory attacks, most existing SSE schemes are no longer secure. Recently, a memory leakage-resilient dynamic SSE (MLR-DSSE) scheme has been proposed to resist memory attacks from physically unclonable functions (PUFs). However, this scheme does not consider …the possibility of dishonest behaviors on the part of cloud servers. In this paper, we first propose a verifiable MLR-DSSE scheme based on PUFs and a verifiable hash table. The construction not only resists memory attacks but also supports verifiable search and dynamic updates. Besides, due to the combination of the secret sharing technique with PUFs, our proposed scheme can recover secret keys even if some PUFs are broken. Furthermore, the security analysis demonstrates that our proposed scheme is non-adaptively secure against memory attacks. The evaluation experiment results show that our scheme is efficient.

Abstract: In recent years, a modern networking paradigm called Software-Defined Networking (SDN) has been introduced to manage the large networks and datacenters. This paradigm was introduced to keep pace with the rapid growth rates on the Internet and to support advanced network applications. SDN uses an open standard protocol called OpenFlow to manage the network traffic. In OpenFlow switches, the software control plane has been decoupled from the hardware data plane and placed in a controller which has a network-wide view. OpenFlow process all incoming packets that have the same characteristics (lie in the same class) in the same manner. In …this paper, we propose and use a generalized extension of BR-tree data structure called AMQ-R tree to organize the rule-sets in a multi-dimensional tree integrated with approximate membership query data structures including Bloom, Quotient and Cuckoo filters in order to get higher quality packet classification performance. Three types of approximate membership query filters integrated with the R-tree have been designed and implemented. Also, a multi-threading technique has been used to accelerate the packet classification by querying the tree in a parallel manner. The experimental results using simulated rule-sets show that this technique can classify incoming packets in up to 1.4 MPPS (Mega Packet per Second) with very small memory requirements. Show more

Abstract: A publish/subscribe (PS) model is an event-driven model of a distributed system. In traditional PS systems, each peer (process) can either publish or subscribe events. In this paper, we consider a peer-to-peer (P2P) type of topic-based PS model where each peer can both publish and subscribe events. In this paper, we newly propose a topic-based access control (TBAC) model for topic-based PS systems. Here, an access right is a pair ⟨ t , op ⟩ of a topic t and a publish or subscribe operation op . A peer is allowed to publish an …event message with publication topics and subscribe interesting topics only if the publication and subscription access rights are granted to the peer, respectively. An event message e is delivered to a peer p i if the publication of e and subscription of p i include some common topic. If a peer p i publishes an event message e 2 after receiving an event message e 1 , the event message e 2 may bring some information of the event message e 1 . If a target peer p j is not allowed to subscribe at least one topic which is related with the event message e 1 , information in the peer p i illegally flows to the target peer p j . We newly propose a subscription-based synchronization (SBS) protocol to prevent illegal information flow. Here, an event message is banned by a target peer if the event message implies illegal information flow. However, event messages may be unnecessarily banned by a peer even if no illegal information flow to the peer occurs. In the evaluation, we show the number of event messages unnecessarily banned in the SBS protocol. Show more

Abstract: With the synchronous development of both cloud computing and machine learning techniques, the resource constrained clients are preferring to outsource the tasks of data storage and computation to the cloud server. However, in this outsourcing paradigm, since the data owners lose the control of their data, it is of vital significance to address the privacy concern of data stored on the cloud server. Hence, many researchers have been focusing on preserving the privacy of training data in learning model. Recently, Wang et al. presented a privacy protection single-layer perceptron learning for e-healthcare (PSLP) by using Paillier cryptosystem. In this paper, …we present that the cloud server can obtain the sensitive training data and weight vector in the PSLP scheme. Besides, based on a symmetric homomorphic encryption algorithm, we propose an efficient and privacy-preserving single-layer perceptron learning scheme in cloud computing, named EPSLP. Security analysis shows that the proposed EPSLP can protect the privacy of training data, intermediate results and the optimal single-layer perceptron predictive models. Finally, we implement the EPSLP scheme and PSLP scheme, and extensive experiments indicate that the EPSLP is efficient in data encryption phase and the training phase of predictive model. Show more
