Tongxin Micro Launches the E450R, the World's First Open-Architecture Security Chip

On August 21, the 2024 Tongxin Micro Partner Conference was grandly opened in Beijing, where Tongxin Micro unveiled its latest technological innovation — the E450R, the world's first security chip with open hardware and software architecture. The open hardware architecture features an open instruction set with enhanced cutting and expansion capabilities, while the open software architecture boasts an efficient instruction set, supporting ISO/IEC international standard languages and structured virtual machines. The newly launched E450R showcases Tongxin Micro's technological innovation strength in data security and algorithm protection, injecting new vitality into the development of a more efficient and open "chip" ecosystem.

Open Hardware Architecture: More Flexible, Faster, and More Open

Thanks to the advantages of RISC-V's open, customizable, and scalable design, the E450R introduces a new anti-attack mechanism, a new asymmetric cryptographic algorithm engine PKE, and an innovative non-volatile memory (NVM) management system. These advancements result in significantly improved performance: the PKE algorithm's speed has been increased by 50%, while maintaining performance even with an increased key bit length; The NVM erase/write speed has been boosted by 15%, enabling the storage of more data within the same erase/write time; and the underlying hardware level's speed has been greatly improved, with typical application transactions increasing by 50%. The open hardware architecture allows the E450R to maintain superior security without compromising speed.

Open Software Architecture: More Versatile, Efficient, and Convenient

The open software architecture provides a complete set of virtual machines, application programming interfaces (APIs), operating system kernels, and application development toolchains. With this architecture, the E450R supports international standard languages for application development and provides structured virtual machines to achieve platform independence. Additionally, it offers an instruction set for efficient application resource utilization, reducing application code size by 30% and accelerating application load times by 120%. This makes application loading more convenient and meets the demands of efficient production management, ensuring the rapid delivery of products worldwide.

Secure without sacrificing speed, efficient without complexity — the combination of open software and hardware architectures enables the E450R to achieve a qualitative leap. The E450R has currently received several authoritative certifications, including UnionPay Chip Security Certification, UnionPay Embedded Software Security Certification, UnionPay IC Card Operating System Product Certification, Chinese Cryptography Level II Certification, and CCRC IT EAL4+ Certification.

As the world's first open-architecture security chip, the E450R fully demonstrates Tongxin Micro's technological innovation strength in open-architecture solutions. Moving forward, Tongxin Micro looks forward to collaborating with all partners to promote the popularization and application of open-architecture products, building a secure, open, and efficient product ecosystem. Through technological and system innovations, Tongxin Micro aims to work with its partners to safeguard the safe development of the digital economy.
