This is a short comparison report about a verification task solved with KeY, Why3, Dafny and Frama-C.
The original challenge comes from a real-world situation. There is no particular “trick” needed for the specification and verification; it is rather straightforward. Yet, the required annotations to achieve the specification are not too few – making the example a good opportunity to compare different specification languages.

KeY Tutorial at VerifyThis 2021
During the VerifyThis competition 2021, KeY was invited to present itself as a Java verification tool.
It is customary for Verify This that for one tool after a brief introduction into the concepts of the tool, the participants are invited to solve a micro challenge – with a little help from present KeY developers.
KeYNote Series
The KeYNote series is a virtual workshop where teams from Germany, the Netherlands, Norway and Sweden (in lexicographic order) take part and present recent work which uses or extends the KeY verification system.
KeY 2.8
After almost 2 years of active development, we present now KeY 2.8 just before the year’s end.

Proving the Correctness of Program Transformations with Abstract Execution and REFINITY
Summary. Abstract Execution (AE) is a new program analysis technique for automatically proving second-order properties about programs. It is based on the symbolic execution of abstract programs with second-order symbolic stores.
