What is Asymmetric Cryptography?

It's common to hear the term asymmetric or symmetric cryptography but what does this actually mean? A brief explanation is that asymmetric cryptography is cryptography that has two keys which is why it is also called public-key cryptography. Both keys in the algorithm are linked to each other in a mathematical way, which allows for using EPKE (Enveloped Public Key Encryption) in the common TLS connection. EPKE using an asymmetric cryptography algorithm allows for security from the message being read and from it being tampered with.

The wolfSSL embedded SSL/TLS library supports several different asymmetric algorithms, including RSA, ECC, and Ed25519!

wolfBoot – wolfSSL’s Secure Bootloader

wolfBoot is wolfSSL's own implementation of a secure bootloader that leverages wolfSSL's underlying wolfCrypt module to provide signature authentication for the running firmware.

The role of a secure bootloader is to effectively prevent the loading of malicious or unauthorized firmware on the target. Additionally, wolfBoot provides a fail-safe update mechanism, that can be interrupted at any time, and resumed at next boot.

wolfBoot is designed to be a portable, OS-agnostic, secure bootloader solution for all 32-bit microcontrollers, relying on wolfCrypt for firmware authentication.

Due to its minimalist design and the tiny Hardware Abstraction Layer (HAL) API, wolfBoot is completely independent of any OS or bare-metal application, and can be easily ported and integrated into existing embedded software solutions.

wolfBoot provides the basis for secure firmware update (OTA) management at boot time, cutting down the development effort needed to implement and validate the required mechanisms to handle the updates. It reduces the development effort to just receiving the image using a secure channel within the application/OS. We recommend using wolfSSL to encrypt the firmware transfer over TLS, to avoid eavesdropping. Once the image is transferred and stored into the update partition, wolfBoot takes care of the update procedure at the next boot.

Remote updates that would lead to a faulty firmware are automatically reverted by wolfBoot after the first 'test' boot, by restoring the original firmware image whenever the update has failed to boot properly. This mechanism protects the target device from accidental updates on the field.

wolfBoot can be downloaded from the wolfSSL download page here: https://www.wolfssl.com/download/

wolfSSL FIPS-Ready

With the release of wolfSSL 4.0.0, the wolfSSL team has also released a new product: the wolfSSL FIPS Ready library. This product features new, state of the art concepts and technology. In a single sentence, wolfSSL FIPS Ready is a testable and free to download open source embedded SSL/TLS library with support for FIPS validation, with FIPS enabled cryptography layer code included in the wolfSSL source tree. To further elaborate on what FIPS Ready really means, you do not get a FIPS certificate and you are not FIPS approved. FIPS Ready means that you have included the FIPS code into your build and that you are operating according to the FIPS enforced best practices of default entry point, and Power On Self Test (POST).

FIPS validation is a government certification for cryptographic modules that states that the module in question has undergone thorough and rigorous testing to be certified. FIPS validation specifies that a software/encryption module is able to be used within or alongside government systems. The most recent FIPS specification is 140-2, with various levels of security offered (1-5). Currently, wolfCrypt has FIPS 140-2 validation with certificates #2425 and #3389. When trying to get software modules FIPS validated, this is often a costly and time-consuming effort and as such causes the FIPS validated modules to have high price tags.

Since the majority of wolfSSL products use the wolfCrypt encryption engine, this also means that if wolfSSH, wolfMQTT (with TLS support), wolfBoot, and other wolfSSL products in place can be tested FIPS validated code with their software before committing.

wolfSSL FIPS Ready can be downloaded from the wolfSSL download page, here: https://www.wolfssl.com/download/

wolfCrypt as an engine for OpenSSL

As many people know, the OpenSSL project is struggling with FIPS, and their new FIPS release is not expected until December 2020. The version of OpenSSL that supports FIPS goes into End Of Life and is no longer supported in December of 2019.

This means that OpenSSL users will not have a supported package for over a year. This is a big issue for companies that rely on security.

 

To fill this breach, wolfSSL has integrated our FIPS certified crypto module with OpenSSL as an OpenSSL engine. This means that:

1. OpenSSL users can get a supported FIPS solution, with packages available up to the 24×7 level,

2. The new wolfCrypt FIPS solution also supports the TLS 1.3 algorithms, so your package can support TLS 1.3,

3. You can support hardware encryption with your package, as the new wolfCrypt solution has full hardware encryption support.

Additionally, should you be using one of the OpenSSL derivatives like BoringSSL, we can also support you.

Contact us at facts@wolfssl.com if you would like to learn more!

We love you.

wolfCrypt FIPS Certificate #3389

The National Institute of Standards and Technology (NIST) has completed the validation of the wolfCrypt module version 4 for an updated Federal Information and Processing Standards (FIPS) 140-2 certificate in addition to its previous FIPS 140-2 certificate. This new certificate includes updated and more secure algorithms added to the wolfCrypt module's boundary, some of which are listed further below.

FIPS 140-2 is a government standard that specifies a software module is compatible and allowed to be used in government systems. This includes such areas as drone software, government databases, and other high-security/high-power uses.

The new FIPS 140-2 validation has certificate #3389. The Operating Environments (OEs) tested are Ubuntu Linux (16.04) and Windows 10 on Intel Core i5 processors. Full details about the OEs can be found on the CSRC certificate page. Additionally, the certificate also includes the following algorithms: AES (CBC, GCM, CTR, ECB), CVL, Hash DRBG, DSA, DHE, ECDSA (key generation, sign, verify), HMAC, RSA (key generation, sign, verify), SHA-3, SHA-2, SHA-1, and Triple-DES.

wolfSSL Contiki OS Port

With every release of the wolfSSL embedded SSL/TLS library, there are multiple feature additions, port additions, and updates. One of the ports that was added to the wolfSSL library recently was a port to Contiki! You can checkout the changes for Contiki in PR #2500 against the contiki-os/contiki github repository!

Contiki is an open source operating system for the Internet of Things. It connects tiny low-cost, low-power microcontrollers to the Internet. Contiki is a perfect match for wolfSSL, which was built for use on embedded and resource-constrained devices with portability in mind. In addition to being highly portable, wolfSSL provides support for the latest and greatest version of the TLS protocol, TLS 1.3! Using the wolfSSL port with your device running Contiki will allow your IoT device to connect to the internet in one of the most secure ways possible.

The Contiki port in wolfSSL is activated by using the "WOLFSSL_CONTIKI" macro when compiling wolfSSL. An example of this on embedded devices would be placing WOLFSSL_CONTIKI into a user_setttings.h file, or by including the option CPPFLAGS="-DWOLFSSL_CONTIKI" if compiling wolfSSL by using autotools.
