OpenSSL in Devices gets cracked when trying to “enhance” randomness

Hi!  The security world has been buzzing this week about two new sets of research into what we will call statistical key cracking.  The hack is one that we would not expect out of your average script kiddie, because it combines sophisticated scanning with mathematical prowess.  The overview story is the first link below.  The second and third links take you to the researchers previews.

We are particularly interested in the work from Nadia Heninger and her team, given that our user base is skewed towards embedded systems.

Our takeaways from this new research are high entropy seeds are vital to proper key generation.  If a high entropy device is available use it, if not, don`t try to write your own.  Connect securely to a remote server where a high entropy seed can be relayed over the SSL/TLS connection.  And don`t stir the RNG between (p) and (q) generation.  This crack is based on a low entropy seed and the stirring between (p) and (q) generation.  wolfSSL avoids this problem in two ways, by using a high entropy seed from /dev/random and by not stirring between (p) and (q) but before each (p) instead.

wolfSSL and LibSCS

wolfSSL is now available as a crypto provider for KoanLogic’s SCS library, LibSCS. SCS, a small cryptographic protocol layered on top of the HTTP cookie facility [RFC6265], allows its users to produce and consume authenticated and encrypted cookies, as opposed to usual cookies, which are un-authenticated and sent in clear text.

From the LibSCS README, “By having a non-tamperable proof of authorship attached, each SCS cookie can always be validated by the originator, making it possible for a server to handle clients` session state without the need to store it locally. In fact, an SCS enabled server could completely delegate the application state storage to the client (e.g. a web browser) and use it, in all respects, as a remote storage device. The result of the cryptographic transformations applied to state data can be used to ensure that its information authenticity and confidentiality attributes are the same as if they were stored privately on server-side.”

You can build LibSCS with wolfSSL by running the following commands. You must have KoanLogic’s makl installed on your development machine (http://koanlogic.com/makl/) to build the package. See the libscs README and INSTALL files for more detailed instructions.

makl-conf –crypto=cyassl

If you have any questions about wolfSSL with LibSCS, please contact KoanLogic (info@koanlogic) or yaSSL (info@yassl.com).

The Gravity

yaSSL currently secures over 50 million points on the internet.  We don’t talk about who is using CyaSSL, for obvious reasons, but the numbers are big and growing.

We take our work seriously, and hope you feel comfortable with our efforts.  We endeavor to build a business, a community, and do the right thing.  We welcome your feedback.  If you believe that we have failed at some point, then let us know.  We’ll correct it.  We’re open source and open minded about what you have to say.  Contact us at info@yassl.com and let us know how we’re doing!

wolfSSL FreeRTOS / OpenRTOS Support

Did you know that the wolfSSL embedded SSL library supports FreeRTOS and OpenRTOS? FreeRTOS is a real-time operating system for embedded devices which is designed to be both small and simple. With an incredibly large user base, FreeRTOS/OpenRTOS supports 27 architectures and is downloaded from over 77 thousand times every year!

Just like wolfSSL, FreeRTOS is open source, royalty free, and very portable. To build wolfSSL for FreeRTOS, uncomment the #define for FREERTOS in ./cyassl/ctaocrypt/settings.h.

You can find a full list of FreeRTOS features on the FreeRTOS/OpenRTOS website. To learn more about wolfSSL, please visit the wolfSSL product page. If you have any questions about using wolfSSL with FreeRTOS, please contact us at info@yassl.com.

Interesting Article on Device Level Security

As the security of individual field devices (sensors, transmitters, acuators, etc.) is often overlooked, these devices can provide a target for cyber attacks. This article by Matt Luallen of Control Engineering explains this fact in more detail – once again reminding us that security of such devices should not be taken lightly. Luallen states that “If your technicians can configure a field device through the control system, dedicated handheld tools, or by plugging in a laptop to the network, an attacker can do the same thing if he follows the right path.”

Secure communication is an important building block of device security. The wolfSSL embedded SSL library has been designed for resource-constrained embedded systems and can easily be added to your device. To learn more about wolfSSL and how it can help with your device security, feel free to contact us at facts@wolfssl.com.

Born in the USA!

We receive a lot of questions about the origins of the CyaSSL and CTaoCrypt software packages.  We get asked where they were developed, and by who?  These questions usually come from US government agencies and their contractors.  Simply stated, mes amis, CyaSSL was Born in the USA and written by US citizens.

If you have any additional questions about the origins of the CyaSSL embedded SSL library, please contact us at info@yassl.com
