SSL (Secure Sockets Layer) + TLS
The NetBurner SSL/TLS implementation was written from the ground up to provide high performance and a small memory footprint of approximately 90K bytes. The SSL/TLS module is integrated with the NetBurner TCP/IP stack and web server, enabling you to add secure web pages to your product with just a few function calls. Unlike 8-bit and 16-bit microcontrollers, the 32-bit NetBurner processor platforms can easily handle the demands of connecting and transmitting data using SSL. Authentication is achieved by using public key certificates, which require a functioning PKI (public-key infrastructure). You can setup a local trusted PKI or use one of the many trusted certificate authorities on the Internet, such as Thawte or VeriSign.
SSH (Secure Shell)
SSH enables secure data exchange between embedded network devices on a network or the Internet. It replaces TELNET and other insecure remote shells with a secure alternative. Server authentication (username and password) is required for security but the administrator can allow anonymous operation.
