See https://www.embedded.com/design/power-optimization/4209515/Robust-design-principles-for-home-smart-grid-metering for a great discussion on smart grid metering.  There’s already wolfSSL users employing our embedded ssl to secure metering systems!  wolfSSL is useful in smart grid metering for the following areas: 1. Delivering secure firmware updates to the metering device.2. Encrypting data between the metering device and the main data store.3. Encrypting data on […]

Have you heard talk about SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 but never really knew the differences between the different versions? Secure Socket Layer (SSL) and Transport Security Layer (TLS) are both cryptographic protocols which provide secure communication over networks. These different versions are all in widespread use today in […]

Did you know that wolfSSL supports running on the RIM PlayBook? The PlayBook runs the QNX operating system, which we have supported for the last five years – ever since our first source release of wolfSSL. We have posted before about wolfSSL`s build sizes on QNX, which are an impressive 80k (compared to a standard […]

See Jack Ganssle’s discussion on the report here:  https://www.embedded.com/electronics-blogs/break-points/4208881/2010-VDC-survey-of-embedded-software.  A couple items stand out for us, as a company providing open source embedded ssl:  1. 46% of embedded developers are using a TCP/IP stack.  What we’d like to know is the subset of those developers using SSL.  If embedded ssl usage maps to general ssl […]

Do you have a need to analyze SSL traffic? Beginning with the wolfSSL 1.5.0 release, we have provided a build option allowing the wolfSSL embedded SSL library to be built with SSL Sniffer functionality. This means that you can collect SSL traffic packets and with the correct key file, are able to decrypt them as […]

wolfSSL is a popular tool for digitally signing applications, libraries or files prior to loading them on embedded devices. As such, it is ideal for signing firmware updates. The reason that embedded RTOS environments do not include digital signature functionality is because it has historically not been a requirement for most embedded applications.  However, in […]

Hi!  Most of our readers will already know that AES is a key encryption standard used by governments worldwide, and that wolfSSL has always supported AES.  Intel has released a new set of instructions that is a faster way to implement AES, and wolfSSL is currently the first ssl library to fully support the new instruction […]
