Because of the movements of sensor nodes and unknown mobility pattern, how to ensure two communicating (static or mobile) nodes authenticate and share a pairwise key is important. In this paper, we propose a mutual-authenticated key distribution scheme based on physical unclonable functions (PUFs) for dynamic sensor networks. Compared with traditional key predistribution schemes, the proposal reduces the storage overhead and the key exposure risks and thereby improves the resilience against node capture attacks. Mutual authentication is provided by the PUF challenge-response mechanism. However, the PUF response is not transmitted in plain forms so as to resist the modelling attacks, which is vulnerable in some existing PUF-based schemes. We demonstrate the proposed scheme to improve the secure connectivity and other performances by analysis and experiments.

Hoc Networks

Wireless Sensor Network (WSN) is a type of ad hoc networks which consist of hundreds to thousands of sensor nodes. These sensor nodes collaborate to surveillance environment. WSNs have a variety of applications in military, industrial and other fields and they are fit to study environments that presence of human being is costly or dangerous. Sensor nodes have memory, energy and processing limitations. According to sensors' limitations and also increasing use of these networks in military fields, establishing a secure WSN is very important and challenging. Applying Key Predistribution Schemes (KPSs) is one of the effective and useful mechanisms to provide security in WSN. In this paper, a hybrid KPS is proposed that support three various keys, primary pairwise, polynomial, and ordinary. The proposed scheme has been implemented using J-SIM simulator and its performance has been evaluated in terms of maximum supportable network sizes and resiliency against node capture attack, by performing some experiments. Simulation results have been compared with Basic, q-Composite, RS, Cluster-Based, QS, and Double-Key Hash schemes. The compared results showed that the proposed scheme has a better resiliency against links disclosing via enemies.

Key Predistribution Scheme

During the lifecycle of sensor networks, making use of the existing key predistribution schemes using deployment knowledge for pairwise key establishment and authentication between nodes, a new challenge is elevated. Either the resilience against node capture attacks or the global connectivity will significantly decrease with time. In this paper, a new deployment model is developed for multiphase deployment sensor networks, and then a new key management scheme is further proposed. Compared with the existing schemes using deployment knowledge, our scheme has better performance in global connectivity, resilience against node capture attacks throughout their lifecycle.

Sensitive Information

Key distribution in Wireless sensor networks is crucial whenever they deployed in critical applications. Cryptography is used to protect sensitive information from disclosure. Key management is important component in cryptography. Cryptography is not useful if keys are disclosed to attackers. Designing an efficient key management for sensor network is a difficult task because of scarcity of computing and memory resources. An efficient key distribution approach is proposed by using mobile agent paradigm rather than client server model. The proposed approach will use good features of both symmetric and asymmetric cryptography. Mobile Agents are used to generate public and private key pairs, update keys and revocation of keys. The proposed scheme in the first level will use mobile agents for public key dissemination and in second level sensor nodes can involve in constructing symmetric keys for secure communication through mutual authentication and encryption with those keys. The proposed method is implemented using NS2 Simulator and results are compared with existing similar methods in terms of evaluation parameters like throughput and resiliency. The proposed method is improved when it is compared with similar existing methods.

Sparse  Wireless  Sensor  Networks  using several  mobile  nodes  and  a  small  number  of  static sensor  nodes  have  been  widely  used  for  many applications,  especially  for  traffic-generated  pollution monitoring.  This  paper  proposes  a  method  for  data collection and forwarding using Mobile Elements (MEs), which are moving on predefined trajectories in contrast to previous works that use a mixture of MEsand static nodes. In our method, MEscan be used as data collector as well as dynamic bridges for data transfer. We design the  trajectories  in  such  a  way,  that  they  completely cover  the  deployed  area  and  data  will  be  gradually forwarded  from  outermost  trajectories  to  the  center whenever  a  pair  of MEs contacts  each  other  on  an overlapping road distance of respective trajectories. The method  is based  on  direction-oriented  level  and  weight assignment.  We  analyze  the  contact  opportunity  for data  exchange  while MEs move.  The  method  has  been successfully tested for traffic pollution monitoring in an urban area.

<p>Wireless Sensor Networks (WSNs) can extant the individual profits and suppleness with regard to low-power and economical quick deployment for numerous applications. WSNs are widely utilized in medical health care, environmental monitoring, emergencies and remote control areas. Introducing of mobile nodes in clusters is a traditional approach, to assemble the data from sensor nodes and forward to the Base station. Energy efficiency and lifetime improvements are key research areas from past few decades. In this research, to solve the energy limitation to upsurge the network lifetime, Energy efficient trust node based routing protocol is proposed. An experimental validation of framework is focused on Packet Delivery Ratio, network lifetime, throughput, energy consumption and network loss among all other challenges. This protocol assigns some high energy nodes as trusted nodes, and it decides the mobility of data collector.  The energy of mobile nodes, and sensor nodes can save up to a great extent by collecting data from trusted nodes based on their trustworthiness and energy efficiency.  The simulation outcome of our evaluation shows an improvement in all these parameters than existing clustering and Routing algorithms.<strong></strong></p>

A key management strategy is presented for heterogeneous wireless sensor networks. The wireless sensor networks have some sensor nodes which have greater power and transmission capability than other nodes have. Both ordinary nodes and heterogeneous nodes are evenly distributed in sensing square area respectively. The pairwise keys between nodes are established through utilizing the concept of the overlap key sharing and the random key predistribution scheme. Analysis and comparison demonstrate that the connectivity and security of wireless sensor networks have been improved obviously even with some heterogeneous nodes.
