Secure Enhanced Wireless Transfer Protocol

When IEEE 802.11i draft[1] proposed TKIP, it is expected to improve WEP on both active and passive attack methods. TKIP uses more sophisticated methods to distribute and manage secret keys and also requires software upgrade only instead of changing hardware equipment. However, implementing TKIP on the exiting equipment, the transmission performance is decreased dramatically. This paper, therefore, proposes a new transfer scheme to enhance previous WEP and TKIP protocols － Secure Enhanced Wireless Transfer Protocol (SEWTP).SEWTP provides an encryption algorithm on top of current hardware that will improve low performance in TKIP but without compromising security level in the mean time. This is achieved by encrypting secret key twice. Secret key will be stored at both access point (AP) and wireless client so that it can be compared and validated.
