This paper presents initial results in a comparative study of formal and conventional techniques in the design of a secure system component: a trusted gateway. The operation of a trusted gateway is briefly introduced. The industrial context of its development is described, as is the form of the experiment. So far, part-formal and conventional design specifications have been produced for the trusted gateway from a common informal requirements document. As part of this process, queries have been raised against the informal requirements. These have been carefully logged, and form the subject of a preliminary analysis presented here. These first results suggest that the use of a formal specification language (in this case VDM-SL) leads to an an increased number of queries, and a bias in the specifier's concerns towards data rather than design issues.
