Device Authentication and Secure Routing in MANET for Internet of Things

Abstract

In the next generation of communication mobile adhoc network (MANET) will play a major role in Internet of Things (IoT).MANET can be defined as a network among a group of nodes with no infrastructure. Internet of Things is the composition of a variety of networks like Wi-Fi, ZigBee, Wireless Sensor Networks (WSNs). MANETs, and Radio Frequency Identifier (RFID). There is a need for the compatibility of MANET with IoT for the deployment of smart infrastructure. Authenticity and security in communication between devices are essential for the realization of IoT with MANET. Authentication and providing security in MANET are always challenging due to its mobility in nature. Devices in IoT are usually resource constrained in energy, memory, computation and bandwidth. Therefore, it is difficult for each node to authenticate all the devices in the network. In this paper, an authentication scheme is proposed without any third party provider to distinguish the authorized and unauthorized devices. This authentication consists of two level process; in the 1st level mutual devices are authenticated, and in the 2nd level secure data routing between the devices is carried out. Mutual authentication is performed by Clustering based on keys and unique identities and by the cluster heads interpreting for secure routing. This scheme ensures the early measure of authenticity for the message requested enters into the IoT networks and disagreement against attacks.

Framework for Conducting and Analyzing Crystal Simulations of Nucleic Acids to Aid in Modern Force Field Evaluation

“…In addition to the 5DNB system discussed in the previous section, we consider five additional crystal systems comprising A-DNA (137D 48 ), Z-DNA(1LJX 49 ), and three other B-DNAs (1D23, 50 119D 51 and 1BNA 52 ) as summarized in Table 1. These systems were chosen for study based on their resolution, size, structural diversity, and near roomtemperature data collection.…”

“…All studied systems except for the A-DNA (137D 48 ) have some form of coaxial stacking of the helices, which is common in nucleic acid crystals. Z-DNA (1LJX 49 ) and the two decamer B-DNAs (5DNB 43 and 1D23 50 ) form uniform columns and behave like "infinite" DNA helices, where the only coaxial interaction between molecules is base stacking. The dodecamer B-DNA (119D 51 and 1BNA 52 ) have zig-zag coaxial stacking induced by the special inter-molecular interactions denoted as Dickerson Interactions (DI) 55 where sets of three base pairs at both ends hydrogen bond with the consecutive molecules.…”

Tuning Ligand Density To Optimize Pharmacokinetics of Targeted Nanoparticles for Dual Protection against Tumor-Induced Bone Destruction

“…Previous studies showed that Gli2 overexpression accelerates cell cycle progression and augments proliferation in tumor cells, whereas Gli2 inhibition blocks tumor growth in vitro and even in vivo when Gli2 is molecularly repressed using genetic techniques in bone metastatic cancer cell lines. 60,61 This motivated the hypothesis that blocking Gli activity in metastatic breast tumors could obstruct their potential to establish in bone and adopt a bone-destructive phenotype. However, histomorphometric analysis of the tibiae from treated mice showed no significant decrease in overall tumor burden in 10% Aln-GANT58-treated mice (Figure S12A).…”
