: A Linear Feedback Shift Register (LFSR) considers a linear function typically an XOR operation of the previous state as an input to the current state. This paper describes in detail the recent Wireless Communication Systems (WCS) and techniques related to LFSR. Cryptographic methods and reconfigurable computing are two different applications used in the proposed shift register with improved speed and decreased power consumption. Comparing with the existing individual applications, the proposed shift register obtained >15 to <=45% of decreased power consumption with 30% of reduced coverage area. Hence this proposed low power high speed LFSR design suits for various low power high speed applications, for example wireless communication. The entire design architecture is simulated and verified in VHDL language. To synthesis a standard cell library of 0.7um CMOS is used. A custom design tool has been developed for measuring the power. From the results, it is obtained that the cryptographic efficiency is improved regarding time and complexity comparing with the existing algorithms. Hence, the proposed LFSR architecture can be used for any wireless applications due to parallel processing, multiple access and cryptographic methods.

With the advent of globalization and fast changing environment, companies are using information and communication systems in the supply chain. Supply chain management information system (SCMIS) has gained a lot of importance because of its ability to reduce costs and increase responsiveness in the supply chain. Review of literature has revealed that the success in implementation of SCMIS and successfully attaining the return expected from the system implemented is a challenge. With such high failure rates scenario, it becomes imperative to identify the risk and the failure factors that may arise during implementation and the ways to tackle these risks. In this chapter, an attempt has been made to establish the challenges, their severity, and improvisation for the successful implementation of SCMIS in the Indian automobile industry. The findings can help the practitioners and managers better understand the challenges, focus the resources, their attention, set up the priorities, and thus improve the chances of successful implementation of SCMIS.
