Strictly speaking, if two principals +are isolated from one another, there is no way for one to know +whether the other exists: all interactions with the environment +do not expose proof of the existence or non-existence of the +other. + +Typically, principals are isolated from one another with +respect to a particular property. Common properties include +information-flow (security) and performance.
