The Design And Implementation Of Provincial CMS2AC Platform

In modern life, the smart card application is very popular. But as a result of various kinds, they bring us a lot of trouble while they are very convenient. In order to satisfying the multi-card integration demand of the market, China Mobile launched its multi-application card:the Chinese mobile multi-domain multi-application card (China Mobile Security and Multi-Space Application Card, referred to as CMS2AC). CMS2AC has wireless radio frequency function, and it can realize relative complicated applications, such as the payment, electronic ticket, VIP identity card and so on. With CMS2AC’s launching, China Mobile’s multi-application platform construction is an inevitable trend.There are many difficulties and special needs in the construction of multi-application platform. From the perspective of the domestic market, single application cards, STK cards and multi-application cards coexist, and they need to be unified managed; from the perspective of application developers, they wish to manage the card applications by themselves, and they care about the security of the integrated multi-application environment; from the perspective of operators, they need to consider how to maximize the use of the original OTA platform, reducing investment and expanding market share.For these problems and needs, this paper makes the following work:1) Analyzing the key technologies of the CMS2AC card, including the management technology, safety strategies and secure channel technology in CMS2AC, illustrating the security of CMS2AC through the security management and secure channel technology.2) On the basis of the platform requirements and approximate analysis, completing the platform framework design and module division, and the design and implementation of the multi-application platform.3) A detailed description of the (U) SIM card application modules process design, the development process, and the method of implementation.4) Finally, a brief description of the main functions of the CMS2AC OTA module and the communication module:CMS2AC interface implementation:key management and update, transmission channel choice and implementation, and SMS gateway and OTA3platform related interface implementation.
