abstract = {Relational program verification refers to the verification
of relational properties, which relate different programs,
different versions of the same program, or the same program
for different inputs. Recently, there is a growing interest
in relational properties. One of the main reasons for this
trend is that relational properties avoid the bottleneck of
having to write complex requirement specifications. Instead,
the programs that are compared serve as specification of each
other. In this chapter, we give an overview of current trends
in relational program verification. We describe the main
scenarios where relational program verification is employed
to ensure dependability of systems, including regression
verification and proving non-interference properties. And we
discuss recent trends in how to use deductive verification to
prove relational properties.}
