Upcoming wolfSSL Webinar: “Network Security Required for Avionics Systems”

We are hosting a special webinar on the Network Security Required for Avionics Systems for our Japan audience on September 29th!  

Webinar Information 

Registration Link: https://us02web.zoom.us/webinar/register/5715959850834/

Date and Time: Tuesday, September 29, 2020 10:00 AM Japan Time 

Speaker: wolfSSL Inc. Software Engineer, Tesfa Mael

About 

The avionics industry is currently moving to encourage avionics manufacturers to offer more interactive connectivity than ever before. The growing threat of cybersecurity attacks in communication systems is no exception in the avionics industry, and systems must be protected from these attacks.

To develop a secure system, you first need to define the required security level requirements. Often, these requirements fall to the relevant system level through a system-wide security assessment. As part of this process, you need a security plan that considers the entire product life cycle. Without a reliable safety foundation in the development life cycle, it is difficult to prove and maintain the safety of a product.

In this webinar, how will the architectural foundation of Deos, a Time & Space Partitioned RTOS that was certified as DO-178 Level A in 1998, and the cryptography and Deos provided by wolfSSL be integrated? Learn how to achieve the secure features that today’s avionics manufacturers need.

What an RTOS vendor needs to provide for safety and security: 

  • · Deos as a foundation for a secure platform 
  • · Secure Boot
  • · Secure Update
  • · Secure Transport
  • · Cryptography (a building block for all of the above)

This webinar will be held in English.

wolfSSL and the Raccoon Attack

wolfSSL did an internal review of the Raccoon Attack, in addition to reaching out to the research team behind the report, to determine if wolfSSL users are affected by this attack.

The report pertains to the use of static DH cipher suites and the re-use of a DH key with DHE cipher suites. The wolfSSL internal review concluded that:

A) wolfSSL does not support static DH.  Conclusion – Not affected
B) wolfSSL ALWAYS generates a fresh key for every connection using DHE cipher suites with TLS 1.2 and lower protocol versions. (Special note: TLS 1.3 is not affected).  Conclusion – Not affected

wolfSSL also received feedback from the research team that DHE-PSK cipher suites suffer from an inherent specification flaw that can leak the “length” of the Pre Shared Key under certain circumstances. This is due to the way the Premaster Secret (PMS) is generated for DHE_PSK cipher suites. The PMS is generated from:

Length | PMS | Length | PSK

The above is hashed and the runtime is affected by the length of the PSK being used. Attackers can measure this runtime remotely by sending ClientKeyExchange messages and measuring the response times to determine the length of the PSK. This is covered in more detail in section 4.2 of the Raccoon Attack paper (link included above and in the Ref below). Long, regular sized PSK’s are typically used but if this is of concern in your application wolfSSL recommends that ECDHE_PSK cipher suites be used in preference to DHE_PSK cipher suites.

Certain weak projects that claim to be secure will not respond to this attack.  You should not use those products or projects because they will expose you. 

For any questions or concerns feel free to contact wolfSSL support at support@wolfssl.com.

TINY-CURL 7.72.0 – MICRIUM

This post has been cross posted from Daniel Stenberg’s blog – originally posted here.

You remember my tiny-curl effort to port libcurl to more Real-time operating systems? Back in May 2020 I announced it in association with me porting tiny-curl to FreeRTOS.

Today I’m happy to bring you the news that tiny-curl 7.72.0 was just released. Now it also builds and runs fine on the Micrium OS.

Timed with this release, I changed the tiny-curl version number to use the same as the curl release on which this is based on, and I’ve created a new dedicated section on the curl web site for tiny-curl:

https://curl.haxx.se/tiny/

Head over there to download.

Why tiny-curl

With tiny-curl you get an HTTPS-focused small library, that typically fits in 100Kb storage, needing less than 20Kb of dynamic memory to run (excluding TLS and regular libc needs).

You want to go with libcurl even in these tiny devices because your other options are all much much worse. Lots of devices in this category (I call it “devices that are too small to run Linux“) basically go with some default example HTTP code from the OS vendor or similar and sure, that can often be built into a much smaller foot-print than libcurl can but you also get something that is very fragile and error prone. With libcurl, and tiny-curl, instead you get:

  • the same API on all systems – porting your app over now or later becomes a smooth ride
  • a secure and safe library that’s been battle-proven, tested and checked a lot
  • the best documented HTTP library in existence
  • commercial support is readily available

tiny and upward

tiny-curl comes already customized as small as possible, but you always have the option to enable additional powers and by going up slightly in size you can also add more features from the regular libcurl plethora of powerful offerings.


wolfSSL offers commercial support packages and consulting for cURL and tiny-curl!  Contact us at facts@wolfssl.com to learn more.

wolfBoot Encrypted Firmware Support Added

Storing encrypted firmware updates with wolfBoot

At wolfSSL, we work together with our customers to better understand the real-life scenarios in embedded security.

One of the concerns that we have been addressing the most when it comes to secure boot is the protection of the ‘data at rest’ when the firmware updates are received and stored on unprotected non-volatile memory supports, such as external SPI FLASH devices or other customized forms of storage.

wolfBoot, our fully open source secure bootloader solution for embedded systems, now supports encrypted external partitions, to safely store your firmware updates during the update process. The algorithm used is ChaCha20, implemented via wolfCrypt.

Each update can now be signed-and-encrypted to be distributed on the target, and the application can set a decrypt key at runtime, using wolfBoot API. This support has been recently merged in master branch and it will be included in the next release.

Here is how to enable it:

  1. Compile the bootloader with the option `ENCRYPT=1`
  2. Create a buffer of 44 random Bytes, and store it into a `secret_key` file. This file now contains the key and vector that will be used for the encryption of the firmware image.
  3. Add the extra step `–encrypt secret_key` to the sign tool invocation. This will generate an extra *_signed_and_encrypted.bin image file
  4. Transfer the _signed_and_encrypted image to the target. The system application can still use wolfBoot HAL to access external devices, because encryption is only enabled in bootloader mode.
  5. Set the secret key and vector in the application via the wolfBoot API call `wolfBoot_set_encryption_key()`. The secret key could be e.g. pre-stored in a secure element, or transmitted during the update through a secure channel.
  6. Initiate the update as usual, with `wolfBoot_trigger_update()`, and reboot. wolfBoot will attempt to decrypt and verify the firmware, and initiate the installation if the verification is successful.

The image stored in the UPDATE partition is always encrypted, including the backup copy of the previously running system during the installation. This ensures that reading out the partition would never reveal its content as long as the secret encryption key is kept safe.

The partition encryption support in wolfBoot is an additional protection for data at rest, when the firmware is stored on external devices where it is not possible to activate any effective read-out protection.

For data in motion, as usual, we recommend transferring the updates using TLS 1.3, and always using encrypted communication towards the firmware consumer device.

Contact us at facts@wolfssl.com and ask how we can help design and integrate tailored custom secure boot solutions specific to your embedded systems.

Best-Tested: Addressing wolfSSL TLS 1.3 Server Concerns In Record Time

At wolfSSL, we love our open-source community and fully support users working with us on our code, whether it’s finding errors or asking for technical assistance. We are always quick to address our security vulnerabilities–one recent example includes the article published by the Daily Swig on “Embedded security: wolfSSL can be abused to impersonate TLS 1.3 servers and manipulate communications” and our speedy response to the situation. 

 

As the Daily Swig narrates, Gérald Doussot, principal security consultant at UK-based cybersecurity firm NCC Group, discovered a high-risk bug in the SanityCheckTls13MsgReceived() function of file tls13.c:6925 that may put networks at risk of man-in-the-middle (MitM) attacks. NCC Group promptly alerted wolfSSL to the vulnerability in its eponymous, flagship product on July 27. 

 

And upon hearing the alert, we immediately addressed this issue. A fix was published on GitHub, then successfully tested by NCC Group, the next day. The patch was incorporated into the next major release, version 4.5.0, which landed on August 19.  The vulnerability (CVE-2020-24613) will affect versions up to 4.5.0 across all wolfSSL platforms that run TLS 1.3.

 

Additionally, our experts wolfSSL always urge users with TLS 1.3 enabled for client-side connections to update to the latest version, after a researcher demonstrated how attackers could use the open source library to impersonate TLS 1.3 servers, then read or modify data passed between clients. Additional sources state: 

 

“Users that have applications with client side code and have TLS 1.3 turned on, should update to the latest version of wolfSSL,” vendor in an accompanying GitHub advisory.

 

“Users that do not have TLS 1.3 turned on, or that are server side only, are NOT affected by this report.”

 

Version 4.5.0 of wolfSSL will assimilate fixes for five other vulnerabilities that may pose a risk of denial-of-service (DoS) attacks, cache timing attacks, side-channel attacks, the leak of private keys, and clear application_data messages in epoch 0 being processed and returned to the application during the handshake. 

 

On the issue, our co-founder, Larry Stefonic stated, 

 

“It was not a tricky fix and we had the fix ready in about 36 hours after the report. [Additionally] Gerald was efficient and easy to work with in his bug submission. He wrote good examples that were easy to reproduce. We are appreciative of that. 

 

Despite having two sets of our internal eyeballs on each line of code, and sometimes three, we need people like Gerald who have the mindset and intellect to find these things.” 

 

So with all the bugs fixed and our newest updates released, we encourage people to continue to look at our code and break it. We look forward to hearing more feedback from our users!
