A correction to `efficient and secure comparison for on-line auctions'
Summary: We describe a correction to the cryptosystem proposed by \textit{I. Damgå rd} et al. [Int. J. Appl. Cryptogr. 1, No. 1, 22--31 (2008; Zbl 1178.94185)]. Although, the correction is small and does not affect the performance of the protocols from Damgard et al., it is necessary, as the cryptosystem is not secure without it. [Concerns also \textit{I. Damgård} et al., in: Information security and privacy. 12th Australasian conference, ACISP 2007. Townsville, Australia, July 2--4, 2007. Proceedings. Berlin: Springer.
