White Paper for the New Generation of Super SIM Chip Technology of China Mobile Was Formally Released, and Tongxin Micro Participated in Its Compilation to a Large Extent

White Paper for the New Generation of Super SIM Chip Technology of China Mobile Was Formally Released, and Tongxin Micro Participated in Its Compilation to a Large Extent

On June 24, China Mobile 2022 Technology Week & Mobile Information Industry Chain Innovation Conference - Number Card Sub-forum was successfully held. This activity themed at "innovative upgrading of number cards and building of the new cornerstone of digital and intelligent ecology" focuses on various innovative upgrading technologies and application cases concerning number cards and invited industry chain partners to jointly explore new approaches and new models for the assistance of number cards in industry development and to jointly build an account ecology, an security ecology and a credit ecology in the digital and intelligent society. On the sub-forum, the White Paper for the New Generation of Super SIM Chip Technology of China Mobile was formally released. The white paper specifies relevant business functions and technical features of the new generation of super SIM cards, aiming to expand the industry ecology and boost benign development of business. Tongxin Micro subordinate to Guoxin Micro participated in to a large extent the compilation of the white paper as the supplier of the core technical proposal and provided a technical proposal for promotion and implementation of the new generation of super SIM cards. Zou Zhongren, the Standing Vice President of Tongxin Micro, systematically elaborated in his speech on the sub-forum the innovative approach of the new generation of super SIM cards and conception of the future ecology. Along with the rapid development of the mobile internet, the SIM card chips based on ROM architecture and Flash architecture have been unable to meet the market demand for increasingly diversified scenarios due to the long masking cycle and the limitation in aspects of communication interfaces, storage capacity, encryption algorithm, etc. Tongxin Micro has launched the super SIM chip based on the finance-level security architecture and has made a breakthrough in terms of the capacity, interface, etc. Based on this architecture, China Mobile developed the super SIM card in 2020. Integrated with multiple scenarios like public travel, financial payment and digital identity verification, this product can bring users with the convenient use experience of "one card integrated with multiple application functions". Zou Zhongren said some problems were found as the super SIM card was continuously promoted and more users began to use the super SIM card: the operation system could not be upgraded in a remote way, the quantity of application loaded was restricted, and the offline transaction experience was not ideal. To solve such problems, Tongxin Micro upgraded the inner chip of the new generation of super SIM card. Enlarge storage capacity The user space of the new generation of super SIM card chip has been upgraded to 2MB, multiplying three times than that of the previous 512KB. With the new generation of super SIM card, can be upgrading online , users do not need to change their card in the offline business hall, more applications can be configured, and more than 30 standard bank card applications can be loaded. Faster computation speed The CPU frequency has increased by 50%. The encryption algorithm computation speed has increased by 3 times. The standard offline transaction speed of products based on the super SIM card can be controlled within 500ms, which is equivalent to the computation level of the special edition of mobile phone with a inner chip. Richer external interfaces The rate has increased by 5 times. It is compatible with multi-way SPI, can be configured with a Bluetooth communication module plug-in to realize Bluetooth SIM, connect the channel between the mobile phone and the card, guarantee secure interaction between SIM card and mobile APP; can also be configured with a storage module plug-in to store a large quantity of user data, such as photos, biometric features, etc. Stable supply Domestic process platforms with more stable supply of materials are selected. Production, testing, encapsulation and other links about chips can be completed in China , ensuring that reliable and fast supply experience can be provided for customers. We believe that through the improvement in the above-mentioned four aspects, the new generation of super SIM card will be able to provide more applications with a larger space for their growth and build for users the usage scenarios featured with full-scenario intelligence and full-life cycle security. Next, Tong Xin Micro will make every effort to assort with China Mobile super SIM card strategy to jointly forge a high-security digital asset safe box based on the super SIM new ecosystem and promote super SIM card to become a digital life necessity of consumers in a real sense.

Jointly Build the Intelligent Traffic Industry Ecosystem  Guoxin Micro Undertook the 18th Asia-Pacific Intelligent Traffic Sub-forum

Jointly Build the Intelligent Traffic Industry Ecosystem Guoxin Micro Undertook the 18th Asia-Pacific Intelligent Traffic Sub-forum

As the achievement display and technical exchange platform featured with the highest level and the largest scale in the intelligent traffic industry in Asia-Pacific region, the 18th Asia-Pacific Intelligent Traffic Sub-forum was held in Chengdu of China on April 27. On the afternoon that day, the "Intelligent Traffic Ecosystem Security" Sub-forum undertaken by Guoxin Micro was successfully held and was chaired by Doctor Su Linlin, the Vice President of the Company.   Scholars, experts and representatives of famous colleges and universities, industry research institutes and famous Internet enterprises gathered on the Internet, including the Dean of School of Transportation Science and Engineering BUAA Professor Yang Shichun, the Deputy Director of CAICT Industrial Institute of Internet and IoT Mr. Luo Song, the Deputy Director of China Industry Innovation Alliance for the Intelligent and Connected Vehicles and Standing Deputy General Manager of CICV Mr. Xin Keduo, the person in charge of Baidu APOLLO information security Mr. Liu Jianhao, et al. to exchange ideas about the latest technical research and application experience concerning the ecosystem in the intelligent traffic field and discussed about the latest development trend of the ecosystem security in the intelligent traffic field.   Doctor Su Linlin, the Vice President of Guoxin Micro, delivered a speech titled Terminal Hardware Security Protection of the Road Traffic System where she mainly elaborated the status quo of the terminal security of the road traffic system, sorting of terminal hardware security problems and terminal hardware security protection technologies. She said that intelligence and connection were important characteristics of intelligent roads, hundreds of millions of intelligent terminals had been connected into the IoT, and there were 0.218 billion IoT terminals in the Chinese intelligent traffic field in 2021. This brings new challenges to the management of the road traffic system. On one hand, a huge number of heterogeneous terminals increase the difficulty of unified standardization management; on the other hand, the terminal security level is generally low, so it is hard to resist attack.   Therefore, she suggested that we should attach high importance to the terminal information security risk in the IoT era, and we should not only take into consideration software security, but also solve hardware security threats. The aforesaid problems can be solved with a full series of hardware security products and solutions, such as chips, UICC card, modules, terminals, etc. In addition, safety interconnection of vehicles can be realized and infrastructure hardware security can be guaranteed by using active identification carriers.   As the product of efficient fusion of traffic transportation and information technology, intelligent traffic has been integrated with the green development of "peak carbon dioxide emissions and carbon neutrality" and the industry layout of Chinese intelligent manufacture represented by new infrastructure. China has successively released a series of policies on promoting development of the intelligent traffic. Guoxin Micro is willing to join hands with partners to deeply explore the application scenarios, create core values and build the intelligent traffic industry ecosystem featured with low carbon and sustainable development.
