A correction to ``Efficient and Secure Comparison for On-Line Auctions''

Ivan Damg{\aa}rd and Martin Geisler and Mikkel Kr{\o}igaard

Abstract: In this note, we describe a correction to the cryptosystem proposed by the authors in "Efficient and Secure Comparison for On-Line Auctions". Although the correction is small and does not affect the performance of the protocols proposed in that paper, it is necessary as the cryptosystem is not secure without it.
