One of the predominant protocols for connected sensors and industrial device security is SSL/TLS. Over the last several years, the new up-and-coming TLS 1.3 specification has been in development. Nearing standardization, TLS 1.3 makes substantial changes to the TLS protocol to allow for better security and performance. This session gives attendees an overview of changes in TLS 1.3, how the protocol works, and what advantages it offers for resource-constrained devices.
