Book review on ?C/TCP-IP by Christian Legare

We’ve integrated wolfSSL with ?C/TCP-IP and can say it is an excellent implementation well designed for embedded systems.  In fact, we can say that the integration process drove us to make some great improvements to our product.  For example, our next release will not require the standard C library for even greater flexibility when implementing SSL.  But more about that later!  Here’s the link to the book review:

Our SSL Programming Tutorial is Up

We have recently released an SSL programming tutorial which walks through the process of integrating wolfSSL into a simple application. The wolfSSL embedded SSL library is used, along with a simple echoserver and echoclient. The echoserver and echoclient examples have been taken from the popular book titled Unix Network Programming, Volume 1, 3rd Edition by Richard Stevens, Bill Fenner, and Andrew Rudoff.

Some of the topics covered in this SSL coding tutorial include:
– Required libraries
– What headers are needed
– Startup and Shutdown of wolfSSL
– Sending Data over an SSL connection
– Importing and using Certificates

The SSL tutorial can be found here: SSL Tutorial. All of the source code for the examples is available for download and is linked to from the SSL tutorial webpage.

wolfSSL and TomatoUSB

Hi!

The TomatoUSB community has integrated wolfSSL into the TomatoUSB Firmware as of release 53. wolfSSL is being used in non-VPN editions of the firmware to provide SSL support for httdp and dyndns. They have upgraded to TLS 1.0 from SSL v 2/3 which was previously being used.

TomatoUSB is an alternative linux-based firmware for powering Broadcom-based ethernet routers. It is a modification of the famous Tomato firmware. Some of the added enhancements include support for USB port, wireless-N mode support, and support for several newer router models.

We always like to support community projects which use our products. If you have an open source project and are using wolfSSL or one of our other products, let us know and we’ll gladly support you. If you have questions or would like more information, please contact us at info@yassl.com.

yaSSL Annual Report

yaSSL made dramatic progress this year on a number of fronts, notably in open source community usage, embedded systems adoption, and technology improvements!  Here’s what we’ve done this year, with an outline of our plans for the year to come in a blog post to follow:
 
1. Participated in 4 industry events, including OSCON, Embedded Live, Embedded Systems Computing, and ARM TechCon. 
1. We launched a new and improved web site including new product support forums.
3. We’ve made significant incremental improvements to our documentation.
4. New partners!  We’ll announce two new resale partners next week!
5. New technology partners: Canonical, Red Hat, Novell, Freescale and Express Logic.
6. Added a new Competitive Upgrade Program for wolfSSL. More details can be found at our Consulting Services page, under “Rip and Replace Competitive Upgrade
 
Our long list of technology improvements includes:
 
1. ThreadX port.  wolfSSL now supports building and running on ThreadX “out of the box”.
2. GoAhead Web Server port.  wolfSSL now builds and runs with the GoAhead Web Server through the wolfSSL OpenSSL compatibility layer.
3. Sniffer.  wolfSSL now has the ability to sniff an SSL session with the server`s private key and decode the application data.
4. Swig.  wolfSSL has a swig interface file to allow multiple language access.
5. Python.  wolfSSL now has some python bindings for CTaoCrypt.
6. AES-NI.  wolfSSL now has AES-NI assembly optimizations for supported Intel hardware “Westmere”.
7. ARM. wolfSSL now has assembly optimizations for fastmath Public Key operations.
8. Mongoose.  wolfSSL now builds and runs with the Mongoose Web Server with the wolfSSL OpenSSL compatibility layer.

14. Certificate generation.  wolfSSL now supports certificate generation.
15. yaSSL Embedded Web Server.  Our “own” web server with wolfSSL for security.
16. Low static memory.  wolfSSL went from a default of 48kB static memory per SSL session to 4kB. (alpha)
17. Low dynamic memory.  wolfSSL decreased runtime dynamic memory use. (alpha)
18. Porting.  Increased the portability/flexibility of using wolfSSL on non-standard build environments with an OS header with defines that control the build.
19. No stdlib.  wolfSSL can now be built without any C standard library headers, developers can now use their own “standard” library plug-in. (alpha)
20. Secure memcache.  wolfSSL can now be used to secure memcache network communication including client/patient sensitive data/health records from internal and external snoopers locally and in the cloud. (beta)
21. Mbed.  wolfSSL can be built and run on the Mbed microcontroller. (alpha)
 
We’re happy with our progress this year, and look forward to making even more improvements next year!  We’ll be going into 2011 with greater resources and plan to move this project and business forward at an even faster rate.

Initial Results of wolfSSL on mbed

Recently we’ve been working on porting wolfSSL over to mbed (http://mbed.org/). Now that we have things working, we can report some initial results. wolfSSL takes 2.9 kB of RAM (10% of total) and 63 kB of Flash (13%).  That includes our test driver code which is about 3 kB.

On our test machine, we ran some benchmarks of CTaoCrypt and compared them to the results of running on the mbed. You can see that the results of running on the mbed were much slower, but not bad for a 96 Mhz processor with very limited memory.

On our desktop machine, for fastmath RSA 1024 bit:

public  RSA: 0.06 milliseconds
private RSA: 0.61 milliseconds

On the mbed for fastmath RSA 1024 bit:

public  RSA:  10 milliseconds
private RSA: 165 milliseconds

If you would like more information about these tests or our products, please contact info@yassl.com.

Statistics and Projections on Connected Consumer Devices

The average consumer in the US will “own 5-10 web-enabled devices by 2014” according to In-Stat.  See here for details:  http://www.embeddedinternetdesign.com/showArticle.jhtml?articleID=228300296 (as of 26 March 2018 at 9:20am MDT, this link is broken and has no alternative). By our reckoning, that means about 200 Million devices that need to be enabled with embedded SSL to assure privacy and safety.  We’ll have our work cut out for us at yaSSL.com, which means we need more staff!  We’re hiring, and if you’re reading this, then you’re probably interested in this kind of embedded systems stuff, you like your command line, engage in arguments over code editors (VI vs. Emacs (we’re a VI shop)), and know how to write small, tight, portable code.  Let us how you would like to contribute or send your resume or CV to larry@yassl.com!

A great article that can act as a primer on extracting data from embedded systems, as well as give some  ideas on securing them in the first place. 

From the article:  “During a forensic autopsy an artificial pacemaker was secured for forensic information analysis. An academic hospital was contacted and they had equipment to read the data from this pacemaker via a wireless interface. The extracted information contained around 10 pages of details like name and date of birth of the patient, timestamps of hospital service, technical parameters, and stored measurement details related to the heart function.”
 
The article is a part of a series of extracts from a useful book called “Handbook of Digital Forensics and Investigation.”

Initial results in porting wolfSSL to the mbed MCU

As previously stated here, wolfSSL is getting ported to the mbed chip.  We’ve done the initial build and the results were pretty good.  wolfSSL takes 2.9 kB of RAM (10% of total) and 63 kB of Flash (13%).  That includes the test driver code which is about 3 kB.  More information to follow!  If you’re interested in building wolfSSL for mbed (http://mbed.org/), let us know and we’ll be happy to support you.
