  Hyperproperties extend trace properties to express properties of sets of
traces, and they are increasingly popular in specifying various security and
performance-related properties in domains such as cyber-physical systems, smart
grids, and automotive. This paper introduces a model checking algorithm for a
new formalism, HyperTWTL, which extends Time Window Temporal Logic (TWTL) -- a
domain-specific formal specification language for robotics, by allowing
explicit and simultaneous quantification over multiple execution traces. We
present HyperTWTL with both \emph{synchronous} and \emph{asynchronous}
semantics, based on the alignment of the timestamps in the traces.
Consequently, we demonstrate the application of HyperTWTL in formalizing
important information-flow security policies and concurrency for robotics
applications. Finally, we propose a model checking algorithm for verifying
fragments of HyperTWTL by reducing the problem to a TWTL model checking
problem.
