Application of synchronous dynamic encryption system in mobile wireless domains

ABSTRACT

Motivated by the tradeoff between security and efficiency performance parameters that has been imposed on all modern wireless security protocols, we designed a novel security system that gained in both parameters. Our system is based on stream ciphers for their speed, but maintaining a much more solid and proven security. Such security strength stems from the novel deployment of permutation vectors and the data records in the regeneration of the secret key. Moreover, the involvement of the former results in an adaptive and efficient data integrity mechanism that relies on error propagations in the data stream. Simulation results show that our security protocol is much faster than peer mechanisms such as WEP and CCMP. Hence, we anticipate a great opportunity to deploy our system in environments with scarce bandwidth, which are the most vulnerable; specifically the wireless domain.
