One of the greatest security issues facing the automotive and aviation worlds is securing connections over CAN bus and its derivative protocols. The big issue with these protocols is that they do not have a method for authenticating who or what they are communicating with, and don’t encrypt the traffic. This leaves them open to […]

wolfMQTT Features
The wolfMQTT library is an implementation of the MQTT Client written in C for embedded use, which supports SSL/TLS via the wolfSSL library. This library was built from the ground up to be multi-platform, space conscious and extensible. And most importantly it integrates with wolfSSL to provide TLS support, for a secure solution out of […]
Read MoreMore TagPost-Quantum Research Results from the pq-wolfssl Team
The pq-wolfssl development team have done an excellent experimental post-quantum integration. We applaud their efforts and wanted to summarize and share some fascinating things that they published in their paper. First we will discuss their scenario and then their conclusions. The team’s objective was to study the possibility of a two-step migration strategy for post-quantum signature […]
Read MoreMore TagIntegration of the Falcon Signature Scheme into wolfSSL
A little while ago we announced support for post-quantum KEM groups and then hybrid groups. We are now proud to announce support for the PQC NIST round 3 finalist signature scheme FALCON. With this announcement, customers can now experiment with fully quantum-safe TLS 1.3 handshakes. From a high level perspective, for every TLS 1.3 connection, […]

Read MoreMore TagWhat’s the difference between TLS vs DTLS?
The main difference is DTLS uses UDP and TLS uses TCP. DTLS stands for Datagram Transport Layer Security and is a communications protocol designed to protect data privacy and prevent eavesdropping/tampering. It is based on TLS protocol and used across web browsing, mail, and instant messaging. Using the DTLS library of wolfSSL, sensor data is […]
Read MoreMore TagwolfSSL Cisco CJOSE Port
The wolfSSL embedded SSL/TLS library has maintained support for the Cisco CJOSE library since version 4.4.0. CJOSE implements Javascript Object Signing and Encryption (JOSE) in C/C++. JOSE is a framework that allows parties to exchange transfer claims in a secure way. The CJOSE library has been ported to work with wolfSSL, the best tested crypto […]
