....their own weaknesses, or might employ probabilistic techniques not expressed in the idealized model. Recently there have been several research e orts to relate the idealized model to cryptographic techniques and the computational model based on probabilistic polynomial time computation, including [7, 16, 23, 25, 26, 3, 2, 9, 4]. While these e orts develop rigorous mathematical settings carried out so far only by hand , it is hoped that they will eventually lead to a new generation of high delity automated tools for security analysis that will be able to express the methods and concepts of modern cryptography. Our ....
....method is discussed in [8] The details of the compiler itself can be expressed in our process calculus, but that falls beyond the scope of this paper. 4 Related work We brie y compare our approach with related work based on interactive Turing machines [7, 9] and secure reactive systems [25, 26, 3, 4]. The approach in [7, 9] is formulated in terms of interactive Turing machines (ITM) which are basically the familiar Turing machines with several additional tapes: read only random input tape, read and write switch tape (consisting of a single cell) and a pair of communication tapes, one ....

....addressed more cryptographic primitives so far. On the other hand, the models of Pfitzmann et al. are more rigorously defined and early examples of tool supported proofs in their models exist [5, 4] using PVS [32] Moreover, the recently published universally composable cryptographic library [6] may pave the way to formal verification of large security protocols within their models. Outline. In Section 2 we review the reactive models for synchronous and asynchronous time. In Section 3, we explain how the embedding works and give a rigorous definition. Starting with a proof sketch of the ....

....sound foundation of the formal methods approach, the results are either specific for passive adversaries [3, 2] or they do not capture the local evaluation of nested cryptographic terms [8, 22] which is needed to model many usual cryptographic protocols. A recently proposed cryptographic library [5] allows for such nesting, but has not been applied to any security protocols yet. Thus, despite of the tremendous amount of research dedicated to the Needham Schroeder Lowe protocol, it is still an open question whether an actual implementation based on provably secure cryptographic primitives is ....
....with the mentioned cryptographic details, hence one naturally assumes that our proof heavily relies on complexity theory and is far out of scope of current proof tools. However, our proof is not performed from scratch in the cryptographic setting, but based on the mentioned cryptographic library [5]. This library provides cryptographically faithful, deterministic abstractions of cryptographic primitives, i.e. the abstractions can be securely implemented using actual cryptography. Moreover, the library allows for nesting the abstractions in an arbitrary way, quite similar to the original ....
