Implementation of High Security Cryptographic System with Improved Error Correction and Detection Rate using FPGA

In this article, an encryption algorithm with an error detection technique is presented for highly secured reliable data transmission over unreliable communication channels. In this algorithm, an input data is mapped into orthogonal code first. After that the code is encrypted with the help of Linear Feedback Shift Register (LFSR). The technique has been successfully verified and synthesized using Xilinx by Spartan-3E FPGA. The results show that the error detection rate has been increased to 100% by proposed encryption scheme is effective and improves bandwidth efficiency

Discriminating neutrino mass models using Type II seesaw formula

In this paper we propose a kind of natural selection which can discriminate the three possible neutrino mass models, namely the degenerate, inverted hierarchical and normal hierarchical models, using the framework of Type II seesaw formula. We arrive at a conclusion that the inverted hierarchical model appears to be most favourable whereas the normal hierarchical model follows next to it. The degenerate model is found to be most unfavourable. We use the hypothesis that those neutrino mass models in which Type I seesaw term dominates over the Type II left-handed Higgs triplet term are favoured to survive in nature.Comment: No change in the results, a few references added, some changes in Type[IIB] calculation

Complexes of Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) with o-aminobenzoic acid

689-692Complexes of o-aminobenzoic acid with Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) have been prepared and characterised by X-ray diffraction patterns, infrared, Mossbauer and photoacoustic spectra. All the complexes -are polymeric and isomorphous with Zn(II) analogue. An analysis of temperature dependence of quadrupole splitting and optical spectral data give the values of ~ 10,840 cm -1, ~ 2930 cm-1, ~ 450 cm-1, ~ 180 cm-1 for 10 Dq, Eg level splitting, tetragonal field and rhombic fields respective y for Fe(OAB)2 system. Mossbauer studies of Fe(OAB)2 indicate that this compound is stable upto 600 K. Ligand field parameters for Ni(II) and Co(II) have been deduced from photo-acoustic spectra
