Abstract

Safety and secrecy are formulated for a deterministic programming language. A safety property is defined as a set of program traces and secrecy is defined as a binary relation on traces, characterizing a form of Noninterference. Safety properties may have sound and complete execution monitors whereas secrecy has no such monitor.
