From recent few years, need of information security is realized by society amd researchers specially in multi-path, unstructured networks as Mobile Ad-hoc Network. Devices connected in such network are self-configuring and small in size and can communicate in infra less environment. Architecture is very much dynamic and absence of central controlling authority puts challenges to the network by making more vulnerable for various threats and attacks in order to exploit the function of the network. The paper proposes, TCP analysis against very popular attack i.e. blackhole attack. Under different circumstance, reliable transport layer protocol TCP is analyzed for the effects of the attack on adhoc network. Performance has been measured using metrics of average throughput, normalized routing load and end to end delay and conclusions have been drawn based on that.

The RFID based communication between objects within the framework of IoT is potentially very efficient in terms of power requirements and system complexity. The new design incorporating the emerging chipless RFID tags has the potential to make the system more efficient and simple. However, these systems are prone to privacy and security risks and these challenges associated with such systems have not been addressed appropriately in the broader IoT framework. In this context, a lightweight collision free algorithm based on n-bit pseudo random number generator, X-OR hash function, and rotations for chipless RFID system is presented. The algorithm has been implemented on an 8-bit open-loop resonator based chipless RFID tag based system and is validated using BASYS 2 FPGA board based platform. The proposed scheme has been shown to possess security against various attacks such as Denial of Service (DoS), tag/reader anonymity, and tag impersonation.

In the context of emerging applications such as IoT, an RFID framework that can dynamically incorporate, identify, and seamlessly regulate the RFID tags is considered exciting. Earlier RFID frameworks developed using the older web technologies were limited in their ability to provide complete information about the RFID tags and their respective locations. However, the new and emerging web technologies have transformed this scenario and now framework can be developed to include all the required flexibility and security for seamless applications such as monitoring of RFID tags. This paper revisits and proposes a generic scenario of an RFID framework built using latest web technology and demonstrates its ability to customize using an application for tracking of personal user objects. This has been shown that the framework based on newer web technologies can be indeed robust, uniform, unified, and integrated.

Software Defined Networking (SDN) has proved to be a promising approach for creating next generation software based network ecosystems. It has provided us with a centralized network provision, a holistic management plane and a well-defined level of abstraction. But, at the same time brings forth new security and management challenges. Research in the field of SDN is primarily focused on reconfiguration, forwarding and network management issues. However in recent times the interest has moved to tackling security and maintenance issues. This work is based on providing a means to mitigate security challenges in an SDN environment from a DDoS attack based point of view. This paper introduces a Multi-Agent based intrusion prevention and mitigation architecture for SDN. Thus allowing networks to govern their behavior and take appropriate measures when the network is under attack. The architecture is evaluated against filter based intrusion prevention architectures to measure efficiency and resilience against DDoS attacks and false policy based attacks.
