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.

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

Benchmarking the wolfSSL Embedded SSL Library

Many of our users are curious about how the wolfSSL embedded SSL library will perform on a specific hardware device or in a specific environment. Because of the wide variety of different platforms and compilers used today in embedded, enterprise, and cloud-based environments, it is hard for us to give generic performance calculations across the board.

To help our users and customers in determining SSL performance for wolfSSL / CTaoCrypt, we provide a benchmark application which is bundled with wolfSSL. wolfSSL uses the CTaoCrypt cryptography library for all crypto operations by default. Because the underlying crypto is a very performance-critical aspect of SSL/TLS, our benchmark application runs performance tests on CTaoCrypt’s algorithms.

The benchmark utility is located in ctaocrypt/benchmark. Typical output may look like:

AES 5 megs took 0.033 seconds, 149.84 MB/s
ARC4 5 megs took 0.017 seconds, 297.23 MB/s
HC128 5 megs took 0.004 seconds, 1185.10 MB/s
RABBIT 5 megs took 0.011 seconds, 453.14 MB/s
3DES 5 megs took 0.236 seconds, 21.18 MB/s

MD5 5 megs took 0.011 seconds, 444.13 MB/s
SHA 5 megs took 0.019 seconds, 261.73 MB/s
SHA-256 5 megs took 0.041 seconds, 122.98 MB/s
SHA-512 5 megs took 0.023 seconds, 213.44 MB/s

RSA 2048 encryption took 0.11 milliseconds, avg over 100 iterations
RSA 2048 decryption took 2.36 milliseconds, avg over 100 iterations
DH 2048 key generation 0.88 milliseconds, avg over 100 iterations
DH 2048 key agreement 0.92 milliseconds, avg over 100 iterations

This is especially useful for comparing the public key speed before and after changing the math library. You can test the results using the normal math library (./configure), the fastmath library (./configure –enable-fastmath), and the fasthugemath library (./configure –enable-fasthugemath).

As always, please contact with any questions or comments.

GCM Encryption Mode Coming to wolfSSL

We`ve started implementing Galois/Counter Mode (GCM) into wolfSSL.  Specifically for use with AES and as a cipher suite for embedded SSL.  One of the benefits of GCM is its efficiency and its performance appears to be pretty good as well.  As an authenticated encryption algorithm it provides both integrity and confidentiality.  We expect to see it more widely adopted in the near future.  If you`re interested in testing AES with GCM or have any question or comments please let us know.

wolfSSL in the Embedded Software Store

A short time ago, we announced the unveiling of the online Embedded Software Store by ARM and Avnet (previous post). Since that time, there has been some feedback on the site itself and many bugs and errors have been fixed.

We wanted to point our readers to the wolfSSL product page on the Embedded Software Store, now that it has been updated. Do you have any feedback on the store itself or on the wolfSSL product page? Do you like the idea of having an online store for your embedded software needs?

We look forward to hearing your thoughts at
