Trusted third parties are security holes (2005)

Copyright (c) 2001, 2004, 2005 by Nick Szabo Introduction Commercial security is a matter of solving the practical problems of business relationships such as privacy, integrity, protecting property, or detecting breach of contract. A security hole is any weakness that increases the risk of violating these goals. In this real world view of security, a problem does not dissapear because a designer assumes it away. The invocation or assumption in a security protocol design of a "trusted third party" (TTP) or a "trusted computing base" (TCB) controlled by a third party constitutes the introduction of a security hole into that design.
