توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
Testing distribution in deconvolution problems
Abstract: In this paper we consider a random variable Y contamined by an independent additive noise Z. We assume that Z has known distribution. Our purpose is to test the distribution of the unobserved random variable Y . We propose a data driven statistic based on a development of the density of Y + Z, which is valid in the discrete case and in the continuous case. The test is illustrated in b...
متن کاملDeconvolution with unknown error distribution
We consider the problem of estimating a density fX using a sample Y1, . . . , Yn from fY = fX ? fε, where fε is an unknown density function. We assume that an additional sample ε1, . . . , εm from fε is given. Estimators of fX and its derivatives are constructed using nonparametric estimators of fY and fε and applying a spectral cut-off in the Fourier domain. In this paper the rate of convergen...
متن کاملDeconvolution of Camera Instrument Response Functions.
Temporal sequences of fluorescence intensities in single-molecule experiments are often obtained from stacks of camera images. The dwell times of different macromolecular structural or functional states, correlated with characteristic fluorescence intensities, are extracted from the images and combined into dwell time distributions that are fitted by kinetic functions to extract corresponding r...
متن کاملDeconvolution Estimator of Treatment Effect Distribution
This study proposes a deconvolution method to estimate the entire distribution of treatment effect of a program. This method utilizes high-order moment information implied by the standard average treatment effect estimator and approximates the underlying treatment distribution using the method of maximum entropy density. Monte Carlo simulations and experiments with real data demonstrate the fle...
