From the initial stages of public key cryptography, mainly two types of cryptosystems were used to overthrow the attacks. Therefore these two cryptosystems called as RSA and El Gamal are mainly preferred and commonly used. They can be used for encryption and decryption as well as digital signatures. In 1985, Victor Miller and Neal Koblitz invented the Elliptic Curve Cryptography that received more attention widely and formed a suitable substitution for the traditional public key cryptosystems like RSA in the application level. For realizing the protocols such as Elliptic Curve Digital Signature Algorithm(ECDSA), Diffie-Hellman key Exchange, Elgamal Encryption and Decryption etc the Elliptic Curve Cryptography is preferred. An algorithm based on modular multiplication called as Karatsuba multiplication is used here for developing the elliptic curve cryptosystem in the Galois field. The finite field operations in the elliptic curve is used in implementing the Elliptic Curve Digital Signature Algorithm. The algorithm confirmed the suitability of the VLSI implementation of the Elliptic Curve Cryptography. © Research India Publications.

We fabricated the polymer Polyvinyl alcohol (PVA) composed with nano entities conducting carbon black (CCB) and monomotrile clay (MMT). The electrical properties as a function of DC bias were disclosed by using an Impedance analyzer. The optimized very high dielectric constant was demonstrated in the range of 105. The basic mechanism of this composite polarization follow Maxwell-Wangner Polarization model confirmed at lower frequency. The entire polarization process was controlled by using an external DC bias voltage (0-20 volts). This investigation may be useful for packaging and electronic applications.

This paper presents an indicator-based approach to highlight the emerging trends in energy security and sustainability for India over the past four decades. It selects four dimensions of Sustainable Energy Security (SES),namely Availability, Acceptability, Affordability and Efficiency and their corresponding indicators to represent SES. Thereafter, using quantitative data, the study establishes that certain indicators show increasing SES, while certain others show decreasing SES for India. Interpretation of these indicators leads to the conclusion that at the dimensional level 'Availability' and 'Efficiency' indicate increasing SES, while 'Acceptability' and 'Affordability' dimensions indicate decreasing SES. This study, therefore, gives valuable insights into the multi-dimensional aspects of SES and the emerging trends in SES for India. © 2013 © 2013 Taylor & Francis.

The green supply chain (GrSC) performance for different industries is varying. It depends on the GrSC framework adoption and its implementation. In this line, this paper discusses the plastic films supply chain for its environmental pollutants through the 'environmental effect multi-fishbone' diagram. The paper reports the five steps suggested for developing the framework for GrSC for plastics. The construct is developed and reported based on the theoretical tools available in the GrSC arena and elaborates 'green supply chain for plastic' as a method for the convergence of the plastic manufacturing industry and the environment. © 2012 Copyright Taylor and Francis Group, LLC.
