Di erential Power Analysis against the Miller Algorithm
ثبت نشده
چکیده
Pairings permit several protocol simplications and original scheme creation, for example Identity Based Cryptography protocols. Initially, the use of pairings did not involve any secret entry, consequently, side channel attacks were not a threat for pairing based cryptography. On the contrary, in an Identity Based Cryptographic protocol, one of the two entries to the pairing is secret. Side Channel Attacks can be therefore applied to nd this secret. We realize a Dierential Power Analysis(DPA) against the Miller algorithm, the central step to compute the Weil, Tate and Ate pairing.

Design of a minimum power , low - voltage supply fully - di erential transconductance ampli er for A / D converters
Two designs of a fully di erential transconductance ampli er to be used in a rst stage of a pipelined 13-Bit A/D converter are developed and presented. A three stage ampli er achieves the lowest power design. The dynamic range speci cation is met according to the expression for noise power indicated in the design speci cation sheet. In this report, anyway, we show that such expression is incorr...

We propose a new technique called Di erential Cluster Analysis for side-channel key recovery attacks. This technique uses cluster analysis to detect internal collisions and it combines features from previously known collision attacks and Di erential Power Analysis. It captures more general leakage features and can be applied to algorithmic collisions as well as implementation speci c collisions...

We propose a new method for evaluating the security of block ciphers against di erential cryptanalysis and propose new structures for block ciphers. To this end, we de ne the word-wise Markov (Feistel) cipher and random output-di erential (Feistel) cipher and clarify the relations among the di erential, the truncated di erential and the impossible di erential cryptanalyses of the random output-...

So far, many methods have been presented to solve the rst-order di erential equations. But, not many studies have been conducted for numerical solution of high-order fuzzy di erential equations. In this research, First, the equation by reducing time, we transform the rst-order equation. Then we have applied Adams-Bashforth multi-step methods for the initial approximation of one order di erentia...
متن کاملDiierential Elimination-completion Algorithms for Dae and Pdae
dae and pdae are systems of ordinary and partial di erential-algebraic equations with constraints. They occur frequently in applications such as constrained multibody mechanics, space-craft control and incompressible uid dynamics. A dae has di erential index r if a minimum of r+1 di erentiations of it are required before no new constraints are obtained. While dae of low di erential index (0 or ...
