Recently, China used the Long March 3B carrier rocket at the Xichang Satellite Launch Center to successfully launch the 30th and 31th Beidou navigation satellites in a “one arrow and two stars†manner. These two satellites belong to the medium-circle earth orbiting satellite and are the seventh and eighth satellites of the Beidou No. 3 in China. At present, the Beidou satellite navigation system already has regional navigation, positioning and timing capabilities, and has begun global networking. According to the plan, the Beidou satellite navigation system will serve the countries along the “Belt and Road†by the end of 2018. Let's take a look at the relevant content.
The Beidou Satellite Navigation System (BDS) is a global satellite navigation system developed by China itself. It is also the third mature satellite navigation system after the United States Global Positioning System (GPS) and the Russian GLONASS satellite navigation system (GLONASS).
Satellite navigation system is an important spatial information infrastructure. Its three basic functions, timing, positioning and navigation services have been deeply integrated into people's daily life and become the basic support for people's information life. Without an autonomous satellite navigation system, national information security will lack reliable protection. For example, the consistency of time in the fields of finance, power, and communications is extremely important, often in the worst of seconds, with numerous losses. If there is an error in the positioning and navigation services widely used in the transportation fields such as automobiles, railways, and airplanes, it may cause a major accident. Not to mention the satellite navigation system is even more indispensable on the battlefield.
With the sharp improvement of the Beidou precision, the application based on Beidou has gradually begun to spread. From the perspective of information security, it is necessary to ensure the security of Beidou applications and securely encrypt and transmit signals.
Datang Microelectronics Technology Co., Ltd., a subsidiary of Datang Telecom, has been immersed in the field of security chips for many years. It has deep technical accumulation in chip anti-attack and chip encryption. The related products have passed the strict international CC EAL5+ security certification, which is the national identity. The main supplier of chip module, social security card chip and financial IC card chip.
Datang Microelectronics proposed the Beidou location encryption solution for Beidou's positioning application, providing a safer Beidou location service with financial-grade security attributes for various applications. The solution is to add a security chip encryption module to the Beidou terminal module, which supports the national secret SM1, SM2, SM3, SM4, and SSF33 encryption algorithms, as well as international DES, 3DES, AES, SHA1, RSA (4096 bits), and ECC (576). Bit) encryption algorithm, with high security attributes such as anti-attack and active/passive physical protection, providing a safe operating environment and storage environment for sensitive data processing, thus achieving high-security data encryption, secure transmission, and mutual interaction between terminals and platforms. Features such as identity authentication can effectively prevent hackers from illegally stealing data and ensure data communication between the terminal and the platform.

The solution supports multiple applications, multiple platforms, including multiple mobile platforms, and can be applied to various industries including the Internet of Vehicles, providing a more secure Beidou positioning service for various industries.
Guided by the “core-end cloud 2.0†strategy, Datang Telecom focuses on the industry market, features security, and lays out key links in the information and communication industry chain such as chips, terminals, networks and services, and provides related products and solutions. As the earliest integrated circuit design enterprise in the country, Datang Microelectronics will continue to deepen the field of security chips and provide high-quality, highly reliable and high-security chip-level security services for various industrial applications.
