Packet decoding using context sensitive parsing

Protocol tester is a project at RMC and Queen's that applies program transformation techniques to protocol data to evaluate the security of network applications. As part of this process, binary protocols are translated into a textual representation. This paper describes a translation process using a context sensitive parser that eliminates the need to write custom code to decode each individual protocol. It is a template driven top down parser augmented by a constraint engine. The constraint engine is used to implement the context sensitive restrictions.
