Resources Documentation The later versions of WAP, primarily targeting the United States market, were designedConsiderable discussion has addressed the question whether the WAP protocol design was appropriate.

In 2009 it continued to have a considerable user base. WAP represents a suite of protocols rather than a single protocol. – weaknesses in any of the two protocol can be used to break the key – different keys for different functions are desirable no session key is established during authentication – access control is not continuous – once a STA has authenticated and associated to the AP, an attacker send messages using the MAC address of STA These clients must use a WAP Gateway which converts between WSP and HTTP. Transaction Layer: This layer contains Wireless Transaction Protocol (WTP). In 2002, WAP forum was merged with various other forums of the industry resulting in the formation of The WAP gateway translates this WAP request into a conventional HTTP URL request and sends it over the internet. A WAP Push is basically a specially encoded message which includes a link to a WAP address.On receiving a WAP Push, a WAP 1.2 (or later) -enabled handset will automatically give the user the option to access the WAP content. Various wireless security protocols were developed to protect home wireless networks. Most modern handset internet browsers now support full HTML, CSS, and most of WAP saw major success in Japan.

Before the introduction of WAP, mobile service providers had limited opportunities to offer interactive data services, but needed interactivity to support This protocol suite allows a terminal to transmit requests that have an The Wireless Application Environment (WAE) space defines application-specific markup languages.

The request reaches to a specified Web server and it processes the request just as it would have processed any other request and sends the response back to the mobile device through WAP gateway in WML file which can be seen in the micro-browser.Attention reader! Don’t stop learning now.
