wolfBoot UEFI Support

We’re happy to announce that we’ve added experimental support to run wolfBoot as an EFI application! The Unified Extensible Firmware Interface (UEFI) is a specification that describes an interface between the operating system (OS) and the platform firmware and it replaces the old BIOS-like firmware. Now wolfBoot can run inside the UEFI environment on Intel x86_64 machines and load and verify other EFI applications.

This means that we can use it to boot and verify Linux (Linux supports booting as EFI application, a.k.a. EFI STUB) on UEFI machines.

UEFI has a several other interesting features that we plan to integrate in the future: such as SecureBoot and TPM.

To try wolfBoot EFI visit our repository on GitHub, you can also run an example on QEMU!

Power Usage Benchmark with EEMBC

The latest benchmarks of wolfSSL power consumption on an STM32L476G device are up (https://www.eembc.org/viewer/?benchmark_seq=13436). What we found is that using wolfSSL’s SP math (with assembly speed ups) is superior on the device. It has a positive impact on both the speed and power consumption.

With the measurements used with EEMBC (https://www.eembc.org/) higher final scores are better. Without using any optimizations in building wolfSSL the power usage collected was 2170 and performance was 502. Once turning on optimizations and SP assembly the power usage was 13200 and performance was 3050.

The energy score is derived from an inverted, weighted, micro Joules per iteration. Similarly the performance is an inverted, weighted, microseconds per iteration. ECDSA operations saw a significant performance and power usage improvement with SP math enabled and assembly optimizations compiled in. ECDSA operations are the biggest resource consumers with TLS handshakes and a good indication of how long and how much power a TLS connection will use.

wolfSSL NXP SE050 Support

We are excited to announce wolfSSL’s support for the NXP SE050. The wolfSSL SE050 port supports a variety of algorithms including: SHA, SHA2-224, SHA2-256, SHA2-384, SHA2-512, AES-CBC, AES-ECB, ECDSA, ECDHE and most notably ED25519 / CURVE25519.

In the tested configuration a Raspberry Pi 2b was connected to the SE050 dev kit through a header board. Please refer to this guide if interested in replicating hardware configuration (https://www.nxp.com/docs/en/application-note/AN12570.pdf).

Below are hardware accelerated benchmarks using the NXP SE050:

MQTT Secure Firmware Update Example

Our wolfMQTT project includes an example for secure firmware update or Over the Air (OTA) update. This example uses the wolfSSL embedded SSL/TLS library to hash/sign the binary image and send it over MQTT. The example has two applications. One is called fwpush, which hashes, signs and publishes the firmware image over TLS to an MQTT broker. The second is called fwclient, which subscribes to the example firmware update topic, receives the firmware image and validates the signature of it. This example is located in examples/firmware.

The latest wolfMQTT releases can be downloaded at:
https://wolfssl.com/download

Documentation for wolfMQTT can be found here:

The latest source code can be found on our GitHub repo at:

wolfSSL Support for ESP-IDF and ESP32-WROOM-32

Are you a user of the ESP-IDF(Espressif IoT Development Framework)? If so, you will be happy to know that wolfSSL has support and example projects in the wolfSSL embedded SSL/TLS library for ESP-IDF.

ESP-IDF is intended for rapidly developing Internet-of-Things (IoT) applications, with Wi-Fi, Bluetooth, power management and several other system features.

The ESP-IDF “Get Started” document can be found here:

https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html

In order to use wolfSSL under ESP-IDF, you need to deploy wolfSSL source files into the IDE. Please see the README.md placed in the “IDE/Espressif/ESP-IDF/” directory of wolfSSL source tree. In addition to that, example projects including TLS server/client, wolfCrypt test and benchmark are also provided. For building these examples, please see each README.md in example projects directories. When working with ESP-IDF, wolfSSL worked with the ESP32-WROOM-32 device.

wolfSSL also has a page that elaborates upon the use of Espressif with wolfSSL and the Espressif hardware devices, located here: https://www.wolfssl.com/docs/espressif/

Our wolfSSL master branch can be cloned here:
https://github.com/wolfSSL/wolfssl

The README.md can be found here:
https://github.com/wolfSSL/wolfssl/blob/master/IDE/Espressif/ESP-IDF/README.md

Additional examples for wolfSSL TLS Client/Server and wolfCrypt test/benchmark applications can be found here:
https://github.com/wolfSSL/wolfssl/tree/master/IDE/Espressif/ESP-IDF/examples

This support is currently located in our GitHub master branch, and will roll into the next stable release of wolfSSL as well.
