Study On Security In Wireless Network Technology

This thesis mainly analyses security in the WTLS and reasons for defects, study two solutions of security in the WTLS which are elliptic curve and RIPEMD160 cryptograph algorithm.The WAP programming model is similar to the WWW programming model, message is transported using a set of standard communication protocols based on WWW. A micro browser in the wireless terminal is analogous to a standard web browser. WML&WMLScript are defined to organize the content of WAP application, and the communication protocols -WSP/WTP/WTLS, are optimized for wireless environment.The WTLS is designed to provide the good security and most of the text in the WTLS specification has been adopted, word to word, from the TLS specification. However many of the changes that were made by WAP forum have led to security problem. In this paper, the security of the WTLS is analysed.Now elliptic curve and RIPEMD160 cryptograph algorithm is two latest methods and do not easily attack.
