Answers to Common Questions from RSA – Part 1

If you’ve been following our blog, you know we are planning on answering some common questions that we were asked during the 2011 RSA Conference.  Today is the first post in this series.  The first questions we will be looking at are:

Does wolfSSL have sniffer, also known as SSL Inspection functionality?
What about resiliency in the TCP reassembly library?

Q:  Does wolfSSL have sniffer, also  know as SSL Inspection functionality?

Yes, wolfSSL has had SSL Inspection (sniffer) functionality since version 1.5.0.  We have provided a build option allowing the wolfSSL library to be built with this functionality.  This means you are able to collect SSL traffic packets and with the correct key file, are able to decrypt them as well.  This is useful for many reasons, some of which include:

– Analyzing Network Problems
– Detecting network misuse by internal and external users
– Monitoring network usage and data in motion
– Debugging client/server communications

To enable SSL Inspection (sniffer) support, build wolfSSL with the “–enable-sniffer” option on *nix or use the vcproj files on Windows. You will need to have pcap installed on *nix or WinPcap on Windows.  To learn more about functions provided and more detailed usage, please see either the wolfSSL Manual, or the “wolfSSL Additional Features” document.

Q:  What about resiliency in the TCP re-assembly library?

The wolfSSL TCP re-assembly library is currently functional, but not resilient.  This is something that several people have asked about, and something we are looking into.  If you have a need for a resilient TCP re-assembly library, or think this would be beneficial to your project, please let us know at info@yassl.com.

Creating Secure Web-Based User Interfaces for Embedded Devices

While at FOSDEM 2011, we had the opportunity to listen to Arnout Vandecappelle’s presentation titled “Creating secure web based user interfaces for Embedded Devices.” We really enjoyed it, and wanted to share it with our readers. You can read the abstract, taken from mind.be, below:

Abstract:

A web interface is the easiest way to add something GUI-ish to an embedded system. However, setting up an Apache and writing CGI scripts requires too much work and overburdens resource constrained systems.. This presentation shows you the best tools to simplify your life for adding an interface to your embedded system. The first step is the Mongoose Embedded Web Server. It is a tiny (40K) yet fully-featured web server that can be embedded directly in your application. Combining it with the efficient wolfSSL library gives you a secure environment. For a more advanced GUI, there is Wt, which completely removes the burden of web programming from you – you`ll hardly even notice there`s a web server in your application!

You can download Arnout’s presentation in both PDF and ODP formats from the mind.be publication page. We’ll also be linking to Arnout’s slides on our media page as well.

Answers to Common Questions to Team yaSSL at the RSA Security Conference

Hi!  If you follow yaSSL, you probably know we were exhibiting at the RSA Security Conference at Moscone last week.  Our next set of posts will answer common questions that we were fielding at the show. Some of the common questions included:
 
– Does wolfSSL have sniffer, also known as SSL Inspection functionality?
– What about resiliency in the TCP reassembly library?
– Can you port wolfSSL to my platform?
– If wolfSSL is open source, then how do you make money?
– Why is there a wolf in the yaSSL logo?
– How do you compare to OpenSSL?
– What does wolfSSL have as far as Certificate Management?
– Is the yaSSL Embedded Web Server similar to Apache / mod_ssl?
– Where is yaSSL located?
– Does the yaSSL Embedded Web Server compete with nginx?

Stay tuned to the yaSSL blog for answers to these questions and more!

wolfSSL+ with NTRU Cipher Suites

wolfSSL+ (pronounced plus) is now available. wolfSSL+ includes NTRU public key encryption. NTRU works well in mobile environments because of the reduced bit size needed to provide the same security as other public key systems. NTRU also isn’t vulnerable to quantum attacks. Several new cipher suites utilizing NTRU are available including AES-256, RC4, and HC-128. Please contact us if you have any questions.

wolfSSL library available for the mbed cloud compiler

For everyone out there prototyping on the cool mbed board (http://mbed.org/), we`ve recently published our wolfSSL TLS/SSL embedded library to their cloud compiler so that developers can easily add it to their project.  It`s available at http://mbed.org/users/toddouska/libraries/wolfSSL/lm43pv .  We also have an example client you can try out at http://mbed.org/users/toddouska/programs/cyassl-client/lm394s .  Now securing connections, even during a prototype, is easily and rapidly attainable.  Please send us any comments or questions.

yaSSL Embedded Web Server 0.2 is Now Available

The second release of the yaSSL Embedded Web Server is now available for download!  New features with this version include a source release, better documentation, examples, and new run-time options.  

Our Web Server is focused on being small, fast, and embeddable.  Features include CGI, SSI, IP restrictions, access and error log support, and SSL among others. The wolfSSL embedded SSL library can be used to secure ports with SSL, giving you a secure connection while maintaining small size and fast speed.  

On an embedded system you can expect to see the yaSSL Embedded Web Server with wolfSSL enabled to come in around 100kB total.  We offer commercial support, consulting, and licenses for use in a wide variety of projects.

If you have any questions, or would like to learn more about the yaSSL Embedded Web Server and how it can help your project, please contact info@yassl.com.

Some of the topics covered in the presentation will include:

– Good Security Practices for MySQL
– Overview of SSL and TLS
– Configuring and Building MySQL with SSL
– SSL Certificate Creation
– Performance Comparison when using SSL
– Data Storage and Encryption

To read the full presentation outline, please visit the conference page: http://en.oreilly.com/mysql2011/public/schedule/detail/17139

Great Article on the Challenges of Smart Utility Meters

Here’s a great article from EE Times on smart utility meter design. Two of the big challenges described in the article are ones that we’ve dealt with before with our current users in the utility space. Securing the meter, and getting updates to the device securely.

wolfSSL embedded SSL is a critical component for both design requirements. It’s not talked about in the article, but the yaSSL Embedded Web Server is also useful when the meter design calls for delivery of web pages from the meter for field service technicians.
