Change Description

SM algorithms in the confidential computing OS

• The confidential computing OS allows encrypting TA image files using SM algorithms.
• Secure storage with SM algorithms in the confidential computing OS

The confidential computing OS enables hardware acceleration with SM algorithms. The TEE OS supports concurrent computing.

The confidential computing OS (iTrustee) of Kunpeng 920 enables hardware acceleration with SM algorithms. The TEE OS supports concurrency. The supported SM algorithms are SM4-ECB and SM4-CBC.

Linear improvement of multi-core performance in the confidential OS

Resolved the problem where performance does not increase when the number of threads (CPU cores) increases in the TEE.

CPU usage optimization in the confidential OS

Optimized the process of using the shared memory and also the display of CPU usage in the TEE OS.
