Abstract

The execution of mobile code can produce unexpected behavior, which may comprise security and correctness of a software system. Proof-Carrying Code allows one to execute mobile code in a safe way by checking a formal proof before the code is executed. However, automatic generation of proofs works only for basic safety properties such as type safety. To apply PCC to functional correctness properties, we propose to verify the source program interactively and then to translate the proof to bytecode. This proof translation is relatively straightforward if the source and target language are similar, such as Java and Java bytecode, but poses challenges for more complex translations. In this paper, we present a prooftransforming compiler for a subset of Eiffel to the.NET CIL. In particular, we show how the
