wolfSSL is excited to announce support for using Silicon Labs Hardware acceleration. The EFR32 family of devices support multiple wireless interfaces with hardware cryptographic operations. wolfSSL can now offload cryptographic operations for dramatically increased performance on the Silicon Labs EFR32 family!
Our new support includes hardware acceleration of the following algorithms:
The new functionality can be enabled by defining WOLFSSL_SILABS_SE_ACCEL. In user_settings.h More details are available in the README.md in wolfcrypt/src/port/silabs of the wolfSSL tree.
Benchmark was performed on an EFR32 Gecko 2 (Series 1) using the xGM210P022.
