Abstract : The language of partial order time expresses the issues central to many problems in asynchronous distributed systems. A secure partial order time service would provide a general method to develop secure protocols for these problems. In this paper, we sketch out these issues and develop one such protocol: signed vector timestamps. The majority of this paper is drawn verbatim from the first author's October 1991 thesis proposal, the first research into security issues for non-scalar time services and the original presentation of the SVT protocol.
