is also increased. In order to allow fast and safe
coexistence, we have defined a symmetric key generation
problem by linear programming then
further proposed a metaheuristic-based key generation
framework. By the experimental results, our
proposed framework can effectively avoid the generation
of weak keys and providemore security for
consumer electronics environment. Moreover, the
proposed framework is not only suitable for DES,
but also for any encryptions as long as they have
the requirement of random key generation such as
3DES, AES, and so on.
