WLAN technologies arebecoming popular and thedevice arewidely usedeverywhere nowadays, somore attentions arepaidtowhenitcomestowireless security. Sincethecurrent security protocol inIEEE802.11 namely WiredEquivalent Privacy isknowntobequite insecure, the IEEE802.1x andIEEE802.11i wereproposed toresolve someproblems in802.11. However, the802.1x still havesome drawbacks andcouldbe hijacked through middleof communication session. In thispaper,we proposed a password-based authentication andkeyexchange protocol suitable to construct a secureconnection forregular communication security. To overcomethedrawbackof password-based protocols causing by shortlength and randomness ofpassword, theproposed protocol usesthe signature techniques ofECDSA andtheauthentication protocol SRPbasedonDiffie-Hellman keyexchange method.

The explosive growth in wireless networks over the last few years resembles the rapid growth of the Internet within the last decade. To protect internal resources, organizations usually purchased and installed an Internet firewall. We believe that the currently deployed wireless access points present a larger security problem than the early Internet connections. A large number of organizations, based on vendor literature, believe that the security provided by their deployed wireless access points is sufficient to prevent unauthorized access and use. Unfortunately, nothing could be further from the truth. While the current access points provide several security mechanisms, our work combined with the work of others show that all of these mechanisms are completely ineffective. As a result, organizations with deployed wireless networks are vulnerable to unauthorized use of, and access to, their internal infrastructure. We present a novel solution that requires no changes or additions to any deployed wireless equipment, and is easily deployed and transparent to end users.
