Abstract:Advanced Metering Infrastructure is a system for collecting, measuring and analyzing power energy use which beside the mentioned parameters is responsible to transmit this information between elements of this network. One of the problems of processing in these networks and the most main installation duct is security in the network. Beside the precautionary operations used for achieving security in AMI, today the usage of intrusion detection systems (IDS) is paid attention as a second blocker defense against network security attacks. According to variations of Intrusion Detection techniques in network, many different designs for applying IDS and AMI have been suggested so far. In this paper we aim to evaluate the newest techniques of operation in abnormality-based IDS in Intrusion Detection and security achievement in AMI against signature-based IDS operation with the use of standard criteria in equal situations experimentally. According to the results from this research we can see that the signature-based methods are not useful in IDS systems applied in AMI network. The measurement on anomaly-based IDS which is using data mining techniques showed very hopeful results. However these methods need some improvements in order to achieve their best place.
A Wireless Sensor Network (WSN) should operate unattended for a long period of time before battery replacement; therefore characteristics such as self-organization and energy efficiency are of utmost importance to the WSN. One way to meet these requirements is to partition the WSN into clusters, where each cluster managed by a Cluster Head (CH) covers a number of cluster members. In this paper we present a novel algorithm to let CHs choose their members such that energy consumption is minimized. This algorithm is compatible with any other existing clustering algorithm and can be used as an extension to them. Our algorithm guarantees that whatever cluster head selection algorithm one prefers, the clusters are formed optimally. Simulation results show that DEED makes a significant improvement in power consumption and network lifetime of existing algorithms.
An approach has been presented in this paper in order to generate a secure environment on internet Based Virtual Computing platform and also to reduce energy consumption in green cloud computing. The proposed approach constantly checks the accuracy of stored data by means of a central control service inside the network environment and also checks system security through isolating single virtual machines using a common virtual environment. This approach has been simulated on two types of Virtual Machine Manager (VMM) Quick EMUlator (Qemu), HVM (Hardware Virtual Machine) Xen and outputs of the simulation in VMInsight show that when service is getting singly used, the overhead of its performance will be increased. As a secure system, the proposed approach is able to recognize malicious behaviors and assure service security by means of operational integrity measurement. Moreover, the rate of system efficiency has been evaluated according to the amount of energy consumption on five applications (Defragmentation, Compression, Linux Boot Decompression and Kernel Boot). Therefore, this has been resulted that to secure multi-tenant environment, managers and supervisors should independently install a security monitoring system for each Virtual Machines (VMs) which will come up to have the management heavy workload of. While the proposed approach, can respond to all VM's with just one virtual machine as a supervisor.
