The work is part of a series of white papers to demonstrate how the SPARK technology, a subset of the Ada programming language supported by formal verification tools, can be applied for the securityhardening of Software libraries. The first white paper of this series, [8], introduced the SPARK technology through the conversion of a C benchmark suite to SPARK. The work demonstrated how the use of the SPARK technology could guarantee the absence of runtime errors without significantly impacting…

RecordFlux: Formal Message Specification and Generation of Verifiable Binary Parsers

A model and a corresponding domain-specific language to formally specify message formats of existing real-world binary protocols and a technique to derive verifiable parsers based on the model, generate efficient code for their implementation, and automatically prove the absence of runtime errors is presented.
