Abstract

This paper deals with and gives some solutions to the problem of how a small device such as a smart card can efficiently execute secret computations using computing power of auxiliary devices like (banking-, telephone-,...) terminals which are not necessarily trusted. One of the solutions shows that the RSA signatures can be practically generated by a smart card.
