Performance Analysis of Secure Integrated Circuits using Blowfish Algorithm

Security is an essential feature of Information Communication Technology (ICT). Information has to be encrypted at the transmitter side to maintain secrecy and decrypted at the receiver side to retrieve the original information for secure data transmission over insecure computer data communication networks. This paper analyzes the performance metrics of blowfish algorithm with and without Wave Dynamic Differential Logic (WDDL) style to incorporate security against differential power analysis. It compares Encryption Time (Et), Decryption Time (Dt) and Total Time (Tt) of Blowfish, Modified Blowfish with and without WDDL logic for secure Integrated Circuits (SIC) [7, 8]. Modified Blowfish with and without WDDL logic yielded good results compared to Blowfish with and without WDDL logic implementation . This paper is implemented using Xilinx webpack9.2i with Verilog Hardware Description language (HDL)

The first structural study on a cyclic tricoordinate phosphorochloridite and a pentacoordinate phosphorane based on 1,2,3,5-protected myo-inositol-a new conformation of 1,3,2-dioxaphosphorinane ring

Treatment of the phosphoramidite {myo-C6H6-2-[OC(O)Ph]-1,3,5-(O3CH)-4,6-(O2P-NH-i-Pr)} with o-chloranil affords the first example of inositol-based pentacoordinate phosphorane {myo-C6H6-2-[OC(O)Ph]-1,3,5-(O3CH)-4,6-(O2P-NH-i-Pr)(1,2-O2C6Cl4)} (9) (X-ray structure) with a trigonal bipyramidal geometry at phosphorus. The six-membered 1,3,2-dioxaphosphorinane ring with the inositol residue has an unusual boat conformation in 9 which is quite different from that found in unrestrained rings investigated before, but is similar to that of its PIII chloro precursor {myo-C6H6-2-[OC(O)Ph]-1,3,5-(O3CH)-4,6-(O2PCl)} (X-ray structure). Also, a convenient and chromatography-free procedure for the protected myo-inositol derivative {myo-C6H6-2-[OC(O)Ph]-1,3,5-(O3CH)-4,6-(OH)2} is reported

Status of Farmer Producers Organizations (FPO) in Andhra Pradesh

A Variety of approaches have emerged over the years to address the problems of small and marginal farmers' agriculture. In order to improve the welfare and living standards of farmers, there is a need to create appropriate ecosystem in the state. Such institutional arrangement/membership-based institutions are found to be the backbone for primary sector. Both Central and State governments are stressing on promoting 'Farmers Producers Organizations (FPOs) as an important strategy for creating an ecosystem for enhancing farmers profit

Characterization of the first hexacoordinate phosphorus compound with S→P←S bonds

The first example of a hexacoordinate phosphorus compound [S{6-t-Bu-4-Me-C6H2O}2]2P+(Cl-· C3H4N2) with two S→P bonds is reported. This compound can be construed as an oxophosphonium salt with double intramolecular coordination by sulfur atoms. X-ray structure reveals a facial arrangement of the ligands with two coordinating sulfur atoms cis to each other. The S→P distance of 2.334 (1) Å is one among very short coordinate bond distances between sulfur and phosphorus

Assessment of physico- chemical properties and microbial community during composting of municipal solid waste (Viz. KItchen waste) at Jhansi City, U.P. (India)

Rapid industrialization and population explosion in India has led to the migration of people from villages to cities, which generate thousands of tons of Municipal Solid Waste (viz. Kitchen waste) MSW (Viz. KW) daily. Jhansi City is well known district of Bundelkhand region of Uttar Pradesh (India) with a geographical area of 502.75 thousand hectare. The district is situated in the South West corner of the region at 24º11' - 25º57' N latitude and 78º10' - 79º23' E longitudes. Population of Jhansi city is near about 4,79, 612. A detail study was conducted in four consecutive years to assess the potential and possibilities of MSW (Viz. KW) composting generated from Jhansi city, Uttar Pradesh. In the present study, we studied physico-chemical parameters and succession of microbial populations during composting process of MSW (Viz. KW) and found that the pH ranged between 7.1-7.9, Temperature 14-65.2°C, Organic Carbon 20-26 %, moisture content  22-66.7 %, nutrients N – 1.16 %, P – 0.04 %,  K – 0.34%, Na – 2.89 % and microbial colonies like Bacteria, fungi, and Actinomycetes were also present in large numbers.Temperature plays an important role in the growth of microbial colonies during composting of Municipal Solid waste (Viz. Kitchen Waste)

A NOVEL REPEATED DISINTEGRATED ALGORITHM FOR RB MULTIPLICATION TO OBTAIN MAX OUTPUT

Within this paper, we've suggested a manuscript recursive decomposition formula for RB multiplication to acquire high-throughput digit-serial implementation. Through efficient projection of signal-flow graph (SFG) from the suggested formula, a very regular processor-space flow-graph (PSFG) comes. Redundant basis (RB) multipliers over Galois Field( ) have acquired huge recognition in elliptic curve cryptography (ECC) mainly due to their minimal hardware cost for squaring and modular reduction. It's proven the suggested high-throughput structures are the most useful one of the corresponding designs, for FPGA and ASIC implementation. By determining appropriate cut-sets, we've modified the PSFG superbly and carried out efficient feed-forward cut-set retiming to derive three novel multipliers which not just involve considerably a shorter period-complexity compared to existing ones but additionally require less area and fewer power consumption in comparison using the others. The synthesis recent results for field gate array (FPGA) and application specific integrated circuit (ASIC) realization from the suggested designs and competing existing designs are in comparison. It's proven the suggested designs are capable of as much as 94% and 60% savings of area-delay-power product (ADPP) on FPGA and ASIC implementation over the very best of the present designs, correspondingly. Both theoretical analysis and synthesis results read the efficiency of suggested multipliers within the existing ones
