Abstract

This paper investigates foundations for the description of, and reasoning about, trust in secure digital communication. We propose a logic, called the Typed Modal Logic (TML), which extends first-order logic with typed variables and modal operators to express agent beliefs. Based on the logic, the theory of trust for a specific security system can be established. Such trust theories provide a foundation for reasoning about trust in digital communication.
