    ABSTRACT:: Although there have been many attempts to develop code
               transformations that yield tamper-resistant software, no
               reliable software-only methods are known. Motivated by
               numerous potential applications, we investigate a prototype
               hardware mechanism that supports software tamper-resistance
               with an atomic decrypt-and-execute operation. Our hardware
               architecture uses a novel combination of standard
               architectural units. As usual, security has its costs. In
               this design, the most difficult security tradeoffs involve
               testability and performance.
