A semantics for a logic of authentication (extended abstract)

Abadi, Martín, Tuttle, Mark R.·1991·Proceedings of the tenth annual ACM symposium on Principles of distributed computing - PODC '91

Abstract

Abstract: Burrows, Abadi, and Needham have proposed a logic for the analysis of authentication protocols. It is a logic of belief, with special constructs for expressing some of the central concepts used in authentication. The logic has revealed many subtleties and serious errors in published protocols. Unfortunately, it has also created some confusion. In this paper, we provide a new semantics for the logic, our attempt to clarify its meaning. In the search for a sound semantics, we have identi ed many sources of the past confusion. Identifying these sources has helped us improve the logic's syntax and inference rules, and extend its applicability. One of the greatest di erences between our semantics and the original semantics is our treatment of belief as a form of resource-bounded, defeasible knowledge. 1

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
