Mobile value-added application scheme based on W- PKI
    Along with the mobile subscriber’s requirements for the convenient mobile commerce, mobile bank and real-time mobile data transmission, service providers need a kind of faster and more secure way to offer value-added service via mobile network.
    SmartCOS/WPKXC , endows SIM card with the function of PKI, supports security encrypt certification of W-PKI, and offers mobile subscribers secure mobile commerce service.
    Wireless Public Key Infrastructure (WPKI), is an optimized extension of traditional PKI for the wireless environment. WPKIs, like all PKIs, enforce m-commerce business policies by managing relationships, keys and certificates. WPKI is concerned primarily with the policies that are used to manage E-Business and security services provided by WTLS and WMLSCrypt in the wireless application environment. It can offer mobile operators cryptographic security service such as encrypt ,digital signature and so on, for kinds of application in different wireless networks.
    In the case of wireless networks, WPKI standards are the most commonly used.
    Public-key infrastructure (PKI) is the combination of software, encryption technologies, and services that enables enterprises to protect the security of their communications and business transactions on the Internet. PKI integrates digital certificates, public-key cryptography, and certificate authorities into a total, enterprise-wide network security architecture. On the e-commerce business, it can ensure confidentiality, data integrity, authentication and non-repudiation.
    With the safeguard of W-PKI, you can go on with commercial activities cushily anywhere mobile phone could be used.

Mobile value-added application scheme based on W-PKI

Mobile application
Security first
    Electronic commerce and mobile telephone technology develop swift and maturely. Now, people can integrate e-commerce with mobile communications to exchange information anywhere. Mobile providers, mobile value-added service providers, banks and smart card manufacturers are cooperating to set up a mobile security business platform of multi-function and multi-channel, such as a mobile value-added service platform which based on the short message mechanism and STK technique. It integrates Internet, mobile network and wireless PKI technique to ensure the security of the on-line business. In future, everybody can connect to the network to browse information, send mail, order goods or bank via the mobile phone.

Remote managing for the mobile value-added application via OTA technology
    In protean market, the mobile providers need the toolkit which can help them to simplify the logistics operation, reduce expenses, ensure the time of coming into the market, prevent the customers run off and increase the value of ARPU.
OTA (Over The Air) is a technology which remotely controls the SIM card and the applications via mobile communications (GSM/CDMA). It is the best solution for updating the value-added service in 2G mobile network. Presently, the dynamic STK business adopts the advanced OTA technology to manage the applications in SIM cards over the air. The subscribers can experience data access as per individual design and service providers can easily create, remotely administer, and personalize new services effectively.

Features of OTA:
l Remote management of SIM card and individual information configuration.
l The convenience of providing the new services.
l The subscribers can remotely customize, update, activate or invalidate service menu according to their favorites.
l The subscribers can remotely edit or strengthen card menu or contents. The personal information can be securely transferred between different cards via the services provided.

Operational principle of OTA

Based on STK and SMS mechanism, the subscribers send out download request from STK card (supporting OTA) via man machine interface, then the network server sends the corresponding service to the SIM card by short message according to the request. Organizing and storing the download data, SIM card realizes homologous STK menu management.
