M-commerce is the way of doing business transactions in the wireless net. Advancement of technology for M-commerce solutions development provide facility for paperless buying and selling of information, products and service through the website typically by using mobile phone service.

The user can view the sites on his mobile phone's browser, can purchase the goods, or services over the wireless net. The Wireless Application Protocol (WAP) is a set of protocols that work with existing standards to make the Internet accessible through digital wireless devices.

A WAP Service Includes 3 Parts.

• The WAP Service provider (mobile service provider).
• The WAP content provider (may be an independent WAP enabled portal or the mobile service provider itself).
• Your WAP enabled mobile phone.

When an user tries to access WAP enabled site through mobile phone , the mobile service provider authenticates him on their WAP server which in turn will transfer him to their WAP gateway. During this time the call rate will be different. The WAP gateway then transfers the user to the WAP service provider who will provide him with services such as news, e-mail etc. WAP phones have a micro browser which allows navigating the content like a conventional browser.

WAP incorporates a protocol called WTLS (Wireless Transport Layer Security) which enables authentication and encryption of data. WAP phones with GSM currently connect at the rate of 9,600 bps compared to 33,600 BPS to 56,000 BPS Introduction of GPRS will bring big changes for download speed through the mobile phone. The document format is WML (Wireless Markup Language).

Issues before MCommerce

Security becomes a great issue as E-commerce and M-commerce services take shape. Issues such as signal interception and decryption used to be security and privacy issues, but with people transmitting credit card information, making financial transactions and accessing customized and personal data with their phones it must be handled properly.
Just as on the fixed-line Internet, information can be intercepted and decoded. The longer the lag between the time the information is sent and it is received, the more opportunity for it to be intercepted. Wireless Internet technologies are all low-bandwidth, high-latency technologies. Most data and Internet services are operating at speeds of 9.6 kb/s to 14.4 kb/s, much slower than the average 56 kb/s dial-up modem. The combined slowness of the connection and the time spent making the connection can make one transmission last from 10 to 40 seconds, an opportunity for the crackers.
Security can be provided using digital signatures, which are the transformation of an electronic message using public key cryptography. Consumers would apply for digital certificates with trusted third parties, and would then be assigned the digital signatures which would tie them to documents signed and can't be reproduced.

WAP Details....Wap site development

Advancement from e-mail to wireless technology has a great impact on the age of convergence. WAP enabled website design and development is the requirement of the day.

The Wireless Application Protocol (WAP) is a set of protocols that work with existing standards to make the Internet accessible through digital wireless devices (typically mobile phones - surfing the web with a mobile phone.).Portals accessible through mobile phones are called mortals. Development is done using WML.

Working of WAP

WAP introduces a third element, a gateway or proxy server, into the conversation. The wireless client sends requests to this gateway, and the gateway in turn requests from the server on the wireless client's behalf. The gateway acts as the interpreter in the conversation between the server and wireless client translating between WAP and HTTP. Communication between the gateway and the origin server is carried out in HTTP 1.1, just as any normal web communication is done. Encoders and decoders located in the gateway reduce the size of information packets to be sent to the wireless client. The main differences in this model are on the side of gateway to client communication.

The WAP Architecture is in Different Layers

• WAE (Wireless Application Environment) : This layer gives the user interoperability with the web via the micro-browser. A combination of Internet and Mobile Telephony technologies reside in this layer in order to provide a wide range of functionality. WML, WML Script and Wireless Telephony Applications (WTA and WTAI) reside in the WAE.

• WSP (Wireless Session Protocol) : Includes services for browser applications, for the wireless client. Basically, an optimized binary form of HTTP 1.1 with the ability to suspend, resume, and migrate sessions. This layer provides the immediate tools for the micro-browser to use in the transfer of information.

• WTP (Wireless Transaction Protocol) : Provides the mechanism for three types of transaction : unreliable one-way requests, reliable one-way requests, and reliable two-way request-reply. These are asynchronous in performance.

• WTLS (Wireless Transport Layer Security) : Based on TLS (Transport Layer Security) for the World Wide Web, WTLS provides data integrity, privacy, and authentication services. This includes encryption and decryption for secured transactions.

• WDP (Wireless Datagram Protocol) : This layer provides the upper layers with the services of the underlying bearers establishing a means of data throughput. This layer is completely transparent to the user.
