Secure and Efficient Off-Line Digital Money
A b s t r a c t No off-line electronic coin scheme has yet been proposed which is both provably secure with respect to natural cryptographlc assumptions and efficient with respect to reasonable measures. We show that off-line coin schemes can be implemented securely and efficiently, where security is proven based on the hardness of the discrete log function and a pre-processing stage, and where...
متن کاملCombined On-Line/Off-Line Test Solutions for Digital Filters
A low-cost on-line test scheme for digital filters, capable of providing an off-line BIST solution, is proposed. The scheme utilizes an invariant of the digital filter in order to detect possible circuit malfunctioning on-line and shares most of this on-line checking hardware with off-line BIST. The analysis performed indicates that 100% fault secureness & 100% fault coverage are possible, if c...
متن کاملOff-line Digital Cash Schemes Providing Unlinkability, Anonymity and Change
Several ecash systems have been proposed in the last twenty years or so, each offering features similar to real cash. One feature which to date has not been provided is that of a payee giving change to a payer for an e-coin in an off-line setting. In this paper, we indicate how an off-line ecash system can solve the change-giving problem. In addition, our protocol offers the usual expected feat...
متن کاملCombining Off- and On-Line Calibration of a Digital Camera
We introduce a novel outlook on the self-calibration task, by considering images taken by a camera in motion, allowing for zooming and focusing. Apart from the complex relationship between the lens control settings and the intrinsic camera parameters, a prior off-line calibration allows to neglect the setting of focus, and to fix the principal point and aspect ratio throughout distinct views. T...
متن کاملOff-Line Learning
The core issue of interactive design is to search for a point in a usually large design space. Previous studies have been looking into searching strategies within the interaction. In this report, we consider how previous records of interactions can help future searching. Recall that an interaction can be considered as a sequence of transitions of states. A state is described by the current samp...
