Iot Devices

Internet of Things (IoT) becomes part of our daily life. IoT has greatly uplifted the human life and has touched many aspect in our life style. IoT devices are sophisticated lowend device having limited computational and energy resources. Most of the cryptographic algorithms are based on complex mathematical calculation which is not feasible to be computed on IoT devices. Hence presently IoT devices lack strong security features. Security and privacy are becoming the real concern for IoT devices. In this paper we are exploring the various cryptographic algorithm which can be used for IoT device authentication and secure communication. The overall system is designed considering the light weight factor, scalability, time complexity and ease of implementation

Programmable Gate Arrays

Field Programmable Gate Arrays (FPGA), as one of the popular circuit implementation platforms, provide the flexible and powerful way for different applications. IC designs are configured to FPGA through bitstream files. However, the configuration process can be hacked by side channel attacks (SCA) to acquire the critical design information, even under the protection of encryptions. Reports have shown many successful attacks against the FPGA cryptographic systems during the bitstream loading process to acquire the entire design. Current countermeasures, mostly random masking methods, are effective but also introduce large hardware complexity. They are not suitable for resource-constrained scenarios such as Internet of Things (IoT) applications. In this paper, we propose a new secure FPGA masking scheme to counter the SCA. By utilizing the FPGA partial reconfiguration feature, the proposed technique provides a light-weight and flexible solution for the FPGA decryption masking.

The Internet Of Things

The Internet of Things (IoT) refers to system in which smart objects interact with each other with the aid of sensors and actuators through wired/wireless connection. When an IoT concept is implemented for real life application, the possibility of the system being attacked increases. The security measures have to be improved to prevent the attacks.  This paper introduces light weight security schemes for authentication and encryption.  This system uses Blom’s scheme for authentication and Elliptic curve cryptography for encryption. Both these schemes are claimed to be light weight and hence is applicable of IoT applications which is a constrained environment.  These security schemes are applied for healthcare system. The system is proved to be strong against the security attacks.

Personalized Services

Internet of Things (IoT) refers the system of interrelated heterogeneous uniquely identifiable devices with the ability to collect data and communicate with each other to enable applications/services. The security and privacy are the two major issues as IoT applications are providing personalized services by collecting users' private, sensitive and confidential data. The traditional cryptographic methods are not appropriate for most of the IoT applications due to resource-constraints. The lightweight block ciphers are the most common solution to provide security and privacy in IoT. In this paper, various popular lightweight block cipher algorithms and their performance metrics are discussed in detail. The comparative performance analysis of the block ciphers are investigated through experimental study in terms of various metrics and their results are presented. Based on the study, we made recommendations to choose a suitable cryptographic algorithm for an IoT environment depending upon the desired level of security and privacy requirements. The detailed directions are also given which can be considered as guidelines for designing new security solutions.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.
