Highly Efficient and Scalable Access Control Mechanism for IoT Devices in Pervasive Environments

Sustainable life-span of WSN nodes using participatory devices in pervasive environment

Wireless sensor network being a dominant prerequisite in the modern pervasive environment has nodes connected with multi-hop to transmit and reinforce continuous monitoring with real-time updates from the field environment. To achieve pervasiveness integrating wireless and physical devices is unavoidable. Numerous self-organized tiny sensor nodes cooperate with each other to form the clusters and the most prominent node act as cluster head (CH). The cluster head pioneered based on its battery forte whose failure affects rest of the communications. In this paper, we discuss on the essential of idle resource sharing using participatory devices as relay nodes along with node failure rate and node density to achieve reliable communication. The earlier performances are observed and results are revealed. Hence we concentrate on minimizing the task of CH using relay nodes such as participatory devices and the faulty nodes are identified over Poisson distribution which observes the failure probability without affecting communication and reduced resource consumption.

A New Primitive For Stream Ciphers Applicable To Pervasive Environments

Abstract omputing devices in pervasive environments have limitations on the following attributes: calculation capacity, power consumption, and chip size. The huge amount of operation required for applications of cryptographic primitives restricts the implementation of these primitives in pervasive environments. In order to overcome such limitations, we propose a new primitive for stream ciphers called PC-AddRotR (Pervasive Computing -Adder Right Rotation). PC-AddRotR is easily implemented by light-weight hardware and fast word-based software. PC-AddRotR efficiently generates sequences of long period and multi-bit sequences. In addition, using aword-based adder with a nonlinear property, it has more resistance against algebraic attacks, which are known to be the strong analysis methods for stream ciphers.

Threshold-based intrusion detection in ad hoc networks and secure AODV

Mobile ad hoc networks (MANETs) play an important role in connecting devices in pervasive environments. MANETs provide inexpensive and versatile communication, yet several challenges remain in addressing their security. So far, numerous schemes have been proposed for secure routing and intrusion detection, with only simulations to validate them; little work exists, in implementing such schemes on small handheld devices. In this paper, we present our approach of securing a MANET using a threshold-based intrusion detection system and a secure routing protocol. We present a proof-of-concept implementation of our IDS deployed on handheld devices and in a MANET testbed connected by a secure version of AODV over IPv6 – SecAODV. While the IDS helps detect attacks on data traffic, SecAODV incorporates security features of non-repudiation and authentication, without relying on the availability of a Certificate Authority (CA) or a Key Distribution Center (KDC). We present the design and implementation details of our system, the practical considerations involved, and how these mechanisms can be used to detect and thwart malicious attacks.
