Please excuse my probably gross misunderstanding of how all this works.
I just started reading SSL & TLS Essentials by Stephen Thomas, and in chapter 1 he talks about how TLS is a separate protocol layer below the HTTP application protocol, and since it is a separate layer, different application protocols may use it (such as FTP).
My question then is if wireless devices use HTTP (they do right?), why do we need a separate protocol for WTLS? Why can't regular TLS be used for wireless devices using HTTP just as it can with wired devices using HTTP?
According to Wikipedia, WTLS is part of the Wireless Application Protocol (WAP) stack, but again if TLS can be used in conjunction with multiple application protocols, why couldn't TLS be used with WAP?
