Tsinghua Unigroup launches the world's first open architecture security chip E450R, which has obtained the National Security Level 2 Certification

On August 22, Unigroup Tongxin released the world's first security chip E450R with both open hardware and software architecture. The chip is used in the fields of data security and algorithm protection, and has obtained multiple certifications including UnionPay chip security certification, UnionPay embedded software security certification, UnionPay IC card operating system product certification, and national secret level 2 certification.

With the help of open hardware architecture, E450R has updated the anti-attack mechanism, asymmetric cryptographic algorithm engine PKE and non-volatile memory NVM management, and optimized performance. The PKE algorithm speed has been increased by 50%, and the performance remains unchanged when the number of key bits is expanded; the NVM erase speed has been increased by 15%, and more information can be stored in the same erase time; the hardware bottom speed has been increased, and typical application transactions have been increased by 50%.

The open software architecture can provide a complete set of virtual machines, application programming interfaces, operating system kernels and application development tool chains. Based on the open software architecture, E450R supports international standard languages ​​for application development, provides structured virtual machines to achieve platform independence, provides instruction sets for efficient use of application resources, reduces the amount of application code by 30%, increases application loading speed by 120%, and enables rapid global product delivery.
