Recent evidence provided by Diebold, Gardeazabal, and Yilmaz (1994) for the post-1973 floating rate period points toward the predictive superiority of a martingale representation of exchange rate evolution over that of an error correction model that assumes rates are cointegrated. This is an appealing result from the perspective of efficient assimilation of randomly arriving information. As a d...

We present an independent security evaluation of the AccuVote Optical Scan voting terminal (AV-OS). We identify a number of new vulnerabilities of this system which, if exploited maliciously, can invalidate the results of an election process utilizing the terminal. Furthermore, based on our findings an AV-OS can be compromised with off-the-shelf equipment in a matter of minutes even if the mach...

Bitcoin as the current leader in cryptocurrencies is a new asset class receiving significant attention in the financial and investment community and presents an interesting time series prediction problem. In this paper, some forecasting models based on classical like ARIMA and machine learning approaches including Kriging, Artificial Neural Network (ANN), Bayesian method, Support Vector Machine...

We examine a natural but improper implementation of RSA signature verification deployed on the widely used Diebold Touch Screen and Optical Scan voting machines. In the implemented scheme, the verifier fails to examine a large number of the high-order bits of signature padding and the public exponent is three. We present an very mathematically simple attack that enables an adversary to forge si...
