Principles of Security and Trust is a broad forum related to the theoretical and foundational aspects of security and trust.

POST was created in 2012 to combine and replace a number of successful and longstanding workshops in this area: Automated Reasoning and Security Protocol Analysis (ARSPA), Formal Aspects of Security and Trust (FAST), Security in Concurrency (SecCo), and the Workshop on Issues in the Theory of Security (WITS). A subset of these events met jointly as an event affiliated with ETAPS 2011 under the name Theory of Security and Applications (TOSCA).

We seek submissions on the foundations of information security, privacy, and trust, relevant for computer science and different application disciplines. This includes results on cryptographic and logical foundations, reasoning methods, tools, and applications. Case studies that reflect the strengths and limitations of existing foundations, methods, and their supporting tools are also welcome, as are more exploratory presentations on open questions.
