WPKI Wireless Public Key Infrastructure (Wireless PKI)
WPKI wireless environment PKI applications can mainly be used in mobile phones and other wireless devices, features include identity authentication, access control, license, transmit confidential data integrity, non-repudiation and so on.
WPKI standards in the process of development of mobile phones and other wireless devices have been considering the computing power and memory deficiencies, and have the encryption and decryption security features, as in the wired environment PKI Applications, WPKI permit regardless of when and where users can freely conduct transactions or other activities which require high data security.
AtWAP1.2.1 version of security-related persons and information transfer includes: WTLS (Wireless Transport Layer Security), server-authentication, WTLS client-authentication, SignText digital signatures, X.509 certificates, as well as WPKI Portal and so on. One, WPKI Portal similar to the wired authentication environment RA (Registration Authority), to provide mobile electronic certificates of other alternative options, such as URL vouchers, mobile phones and so on-chip key.
However, WPKI has its shortcomings. WPKI currently only applies to WAP protocol, the reasons for its development is limited by the terminal from the mobile phones and other devices with limited support for degree. In other words, mobile phones must meet the above criteria WAP1.2.1 before use, but at the moment of the types of mobile phones are still the minority. In addition, WPKI standard SIM card memory required for large, generally used by mobile phone SIM chip have to be upgraded.
In architecture, WPKI no difference with the PKI. Main operating mechanism for registration and secure transactions for PKI two categories. When the phone holder to the Registrar (PKI Portal) application for certificates from the registrar, once approved, information will be sent to the user to wait for certificates issued by certificate body, while giving the mobile phone holder of a certificate of the URL location. At this point, the certificate body will pass the certificate certificate database for future reference. After the completion of the action, the cell phone holder has been verified through phone trading.
When it comes to transactions, cell phone holders will be first through the WTLS security under the control of access to WAP Gateway (Gateway), then through general Internet use SSL, or TLS security mechanisms in order to enter the content server (Content Server). At this point, an action under the business or e-commerce site will work with the certificate server database to verify than the right, if the information is correct, then the transaction can be approved for.

WSDL Web Services Definition Language
XML Web services WSDL is the description of a standard XML format, WSDL from Ariba, Intel, IBM and Microsoft and other developers make. It has nothing to do with a kind of abstract and concrete language defined by a given Web service operations and information about sending and receiving.
On its definition, can not object as a WSDL interface definition language, for example, CORBA or COM applications such as architecture, will be used in an object interface definition language. WSDL to maintain neutrality agreement, but it does built-in support for SOAP, which was established with the SOAP inextricably linked.
WSDL agreements have been submitted to the Internet standards body W3C review, is still in the "confirmed the authors" state. W3C maintains formal standardized system at the same time, the submission of proposals must go through an approval process to be determined eventually become an official agreement. In this case, WSDL standards organization for at least consider becoming a part of possible future standards.

WTLS (Wireless Transport Layer Security)
WTLS is an industry-standard TLS Protocol determined on the basis of security agreements, mainly operates in the transport layer above the layer of security (Security Layer), apply to the smaller bandwidth of the communication environment.
Wireless security technology can be divided into two categories, namely, wireless network security and the security newsletters (SMS Security). Newsletter in which security technologies, including WTLS andWPKI (Wireless PKI)Both of which are WAP Under the protocol, one of the four levels.
WTLS functionality is similar to the global Internet (WWW) uses SSL encryption transmission technology, the use of encryption technology, you can ensure that the information on the transmission of confidentiality.
Action-banking applications, for example, in the transaction process, mobile phone holders to enter the telecommunications service provider's WAP gateway unit, you must first pass the test of WTLS security mechanism, through data encryption After the conversion, re-entering the bank server.
Subsequently, the bank issued to the users "travel document" (Navigation Document), the user can use this document, and then adopted by WTLS banks WAP gateway, and then enter a non-public security zones to complete financial transactions.
