    Abstract
    The research community made enormous progress in the past years in developing algorithms for verifying software, as shown by verification competitions (SV-COMP). However, the ultimate goal is to design certifying algorithms, which produce for a given input not only the output but in addition a witness. This makes it possible to validate that the output is a correct solution for the input problem. The advantage of certifying algorithms is that the validation of the result is —thanks to the witness— easier than the computation of the result. Unfortunately, the transfer to industry is slow, one of the reasons being that some verifiers report a considerable number of false alarms. The verification community works towards this ultimate goal using exchangeable violation witnesses, i.e., an independent validator can be used to check whether the produced witness indeed represents a bug. This reduces the required trust base from the complex verification tool to a validator that may be less complex, and thus, more easily trustable. But existing witness validators are based on model-checking technology — which does not solve the problem of reducing the trust base. To close this gap, we present a simple concept that is based on program execution: We extend witness validation by generating a test vector from an error path that is reconstructed from the witness. Then, we generate a test harness (similar to unit-test code) that can be compiled and linked together with the original program. We then run the executable program in an isolating container. If the execution violates the specification (similar to runtime verification) we confirm that the witness indeed represents a bug. This method reduces the trust base to the execution system, which seems appropriate for avoiding false alarms. To show feasibility and practicality, we implemented execution-based witness validation in two completely independent analysis frameworks, and performed a large experimental study.

    Abstract
    Verification is a complex algorithmic task, requiring large amounts of computing resources. One approach to reduce the resource consumption is to reuse information from previous verification runs. This paper gives an overview of three techniques for such information reuse. Conditional model checking outputs a condition that describes the state space that was successfully verified, and accepts as input a condition that instructs the model checker which parts of the system should be verified; thus, later verification runs can use the output condition of previous runs in order to not verify again parts of the state space that were already verified. Precision reuse is a technique to use intermediate results from previous verification runs to accelerate further verification runs of the system; information about the level of abstraction in the abstract model can be reused in later verification runs. Typical model checkers provide an error path through the system as witness for having proved that a system violates a property, and a few model checkers provide some kind of proof certificate as a witness for the correctness of the system; these witnesses should be such that the verifiers can read them and -with less computational effort- (re-) verify that the witness is valid.
