We (re-) introduce the Reduce-By-Feedback scheme given by Vielhaber (1987), Benaloh and Dai (1995), and Jeong and Burleson (1997). We show, how to break RSA, when implemented with the standard version of Reduce-by-Feedback or Montgomery multiplication, by Differential Power Analysis. We then modify Reduce-by-Feedback to avoid this attack. The modification is not possible for Montgomery multipli...

In this presented work we designed the 4- bit Arithmetic & Logical Unit (ALU) by using different modules. The Various modules are AND gate OR with six transistors, While XOR is both eight transistors transistors. transistor module gives optimized results. Another one four multiplexer implemented Pass logic (PTL) style. full adder 18 through PTL Here because of style number count such that c...

Adders, as one of the major components of digital computing systems, have a strong influence on their performance. There are various types of adders, each of which uses a different algorithm to do addition with a certain delay. In addition to low computational delay, minimizing power consumption is also a main priority in adder circuit design. In this paper, the proposed adder is divided into s...

(2) signal preprocessing path; (3) signal post-processing path. In this paper, a new transducer to system interface is developed to suppress the noise from the transducer and its interface to system. Several features unique to the transducer to system interface that could help suppress the noise from the transducer and its interface to the system (1) differential input is adopted in the front e...
