Foundations and applications for secure triggers

"Imagine there is certain content we want to maintain private until some particular event occurs, when we want to have it automatically disclosed. Suppose furthermore, that we want this done in a (possibly) malicious host. Say, the confidential content is a piece of code belonging to a computer...
