What is WAP (Wireless Application Protocol)?
WAP (Wireless Application Protocol) is an open specification for displaying content on wireless devices. WAP supports XHTML for message format. WAP supports WTSL (Wireless Transport Layer Security) and PKI (Public Key Infrastructure) for security. WAP clients exist for platforms as varied as PalmOS, EPOC, Windows CE, FLEXOS, OS/9, and JavaOS. WAP rides over data networks as varied as CDPD, CDMA, GSM, PDC, PHS, TDMA, FLEX, ReFLEX, iDEN, TETRA, DECT, DataTAC, Mobitex and GRPS. Some WAP devices support 128 bit WTLS keys, while other WAP devices do not. Security is therefore difficult for the average user to gauge.
