IIJ11-01Implementation of 2 Stage and Pipelined AES for FPGA 

AUTHORS: Mahipal Singh Raghuwanshi, Santosh Onkar, Kiran Sharma

ABSTRACT: The Advanced Encryption Standard is the data security standard referred to as Federal Information Processing Standard 197 (FIPS 197) acquired worldwide by several private and public sectors for protective needs of data storage and secure data application from mobile consumer products to high end user. Most of the AES implementation for reconfigurable devices however based on the configurable logic such as flip-flops and lookup tables. In this paper all the three modules i.e. AES – 128, AES – 192 and AES – 256 are implemented on Spartan 3 XC3S1000L speed grade -4 FPGA. All the three modules are implemented with two techniques namely, sequential 2 stage and pipelined then a performance of the two techniques is evaluated. It is observed from the implementations that sequential 2 stage technique is most area efficient technique, whereas pipelined technique is most time efficient technique.

Keywords: AES, FPGA, Rijndael Algorithm, FIPS – 197, Pipelined architecture, sequential architecture.

Abstract: Performance analysis of steam turbine is shows the enervative ideas to increase the efficiency of turbine and get optimum condition of operation by using various loads on turbine and also less amount of steam consumption by varying temperature and pressure under the certain limit. This is done by three parameters such as steam temperature and pressure of steam and mass flow rate of steam on the 100% load, 75% loads and on 50% load. In order to get optimum performance of steam turbine under the various load on the turbine. For calculation of turbine work and pump work analysis of rankine cycle are use and by the analysis of rankine cycle we calculate the efficiency of turbine and pump on the basis of steam condition at inlet and outlet. For this on the various loads we measure seven temperature and pressure decreasing in same manner, than calculating steam consumption and turbine efficiency.


IIJ11-03:Effect of Stone Dust on Strength of Concrete

AUTHORS: Alok  Patel,  Kapil soni

Abstract— In the present study by-product of stone crushed, stone dust is replaced as a fine aggregate in the concrete by some proportion and compressive strength is determined for concrete by testing the sample cube. The properties such as the specific gravity, moisture content, fineness modulus etc. are determined for the sample. Stone dust is best alternative for the natural sand because natural sand and stone dust has similar physical and mechanical properties. This paper shows some relevant studies regarding the effect of stone dust on mechanical property like compressive strength. Hence in this paper strength and properties of conventional concrete and stone dust concrete are compared so that it will be helpful to other researchers.

Key words: Compressive Strength, Concrete, Natural Sand, Mechanical Properties, Stone Dust
