On Fair Exchange, Fair Coins and Fair Sampling

We study various classical secure computation problems in the context of fairness, and relate them with each other. We also systematically study fair sampling problems (i.e., inputless functionalities) and discover three levels of complexity for them. Our results include the following: – Fair exchange cannot be securely reduced to the problem of fair cointossing by an r-round protocol, except w...

Prompt Delay

Delay games are two-player games of infinite duration in which one player may delay her moves to obtain a lookahead on her opponent’s moves. Recently, such games with quantitative winning conditions in weak MSO with the unbounding quantifier were studied, but their properties turned out to be unsatisfactory. In particular, unbounded lookahead is in general necessary. Here, we study delay games ...

FAIR: Fair Audience InfeRence

Given the recent changes in the policy governing Internet content distribution, such as the institution of per listener royalties for Internet radio broadcasters, content distributors now have an incentive to under-report the size of their audience. Previous audience measurement schemes only protect against inflation of audience size. We present the first protocols for audience measurement that...

چکیده مهارت شنیداری برای مدتهای طولانی در آموزش ، تحقیق و ارزیابی مورد غفلت قرار گرفته است. اگرچه در سالهای اخیر به خاطر اهمیت قابل ملاحظه این توانائیها در آموزش و آزمون زبان ، توجه بیشتری به توانائیهای شنیداری شده است. هم چنانکه درک شنیداری در آموزش و ارزیابی زبان دوم اهمیت فزاینده ای می یابد محققین سعی نموده اند تا ماهیت مهارتهای مستتر در مهارت شنیداری را مورد بررسی و مطالعه قرار دهند. هدف ...
