In earlier work, Necula and Lee developed proof-carrying code (PCC) [3,5],which is a mechanism for ensuring the safe behavior of programs. In PCC, a program contains both the code and an encoding of an easy-to-check proof. The validity of the proof, which can be automatically determined by a simple proof-checking program, implies that the code, when executed, will behave safely according to a user-supplied formal definition of safe behavior. Later, Necula and Lee demonstrated the concept of a certifying compiler [6,7].Certifying compilers promise to make PCC more practical by compiling high-level source programs into optimized PCC binaries completely automatically, as opposed to depending on semi-automatic theorem-proving techniques. Taken together, PCC and certifying compilers provide a possible solution to the code safety problem, even in applications involving mobile code .
