We have received many inquiries about wolfSSL’s µITRON support for years.
The fact that µITRON is used so widely by wolfSSL customers is unique to Japan, but wolfSSL supports µITRON in all wolfSSL products to meet the needs of Japanese customers.
ITRON is an RTOS specification definition, so it is available in many commercial versions, including the open source TOPPERS/ASP, eT-Kernel (eSOL), µC3 (eForce), NORTi (MISPO), and many others. There are also cases where companies have developed their own µITRON-compliant RTOS and are using it, and there are many derivative versions of µITRON that have their own functional enhancements and specification changes.
wolfSSL supports all µITRON versions, including these derivatives.
wolfBoot is available for secure boot, and wolfHSM is available for more robust systems using HSMs (hardware security modules), which have recently been gaining attention.
HSM is a technology that isolates the root of trust functions, such as signature verification and encryption processing, into a physically independent processor or isolated execution context, dramatically improving the security of encryption keys and encryption processing. While HSM’s may make it easier to achieve physical robust security, there is also the issue that the functions such as encryption algorithms provided by the HSM processor are limited. wolfHSM is a framework that makes it possible to expand the encryption algorithm functions as needed by integrating software encryption processing with the basic functions provided by such chips. It is also possible to use the latest quantum-resistant encryption algorithms developed by wolfSSL, as well as algorithms such as SM2, SM3, and SM4.
