Methods MWEP is based on pseudo random number generator (PRNG) and asymmetric cryptograph approach, it generates a unique session key like “One Time Password” for each data frame transmission between any two mobile stations. Results Using this session key to encrypt the transmission data, not only can it avoid replay attack, but also provide a good secure virtual channel for the sender and receiver. MWEP can be incorporated into IEEE 802.11. Conclusion It shows that the proposed mechanism is effective and practical after comparison with WEP and simulation.展开更多
