Personal Identification Numbers (PINs) are commonly used as an authenti-cation mechanism. An important security requirement is that PINs should be hard to guess for an attacker. On the other hand, remembering several random PINs can be difficult task for an individual. We evaluate several dictionary-based methods of choosing a PIN. We experimentally show(More)
Oblivious transfer protocol is a basic building block of various cryptographic constructions. We propose a novel protocol – batch oblivious transfer. It allows efficient computation of multiple instances of oblivious transfer protocols. We apply this protocol to improve the fast simultaneous contract signing protocol, recently proposed in [11], which gains(More)
