Far more than a "secure telnet", SSH is a small and sophisticated suite of protocols which provide for authenticated and encrypted communication via "tunnels" and allow the easy addition of security to your existing embedded application. Having established an SSH session a tunnel between two systems, multiple channels (TCP connections) can securely communicate over that session and do so in a way completely transparent to most applications.
InterNiche's SSH Server is a "ground up" implementation of the SSH Suite specifically for use in embedded products. Its small footprint, portable design is written in "C" and will maintain secure tunnels between your system and any client system you specify. The SSH Server is portable to any multitasking or "No-OS" architecture on either big or little-endian systems and can simultaneously operate over TCP/IPv4 and IPv6.
InterNiche is the specialist in royalty-free embedded TCP/IP protocols optimized for maximum performance and minimum memory footprint and are provided as source code. NicheStack IPv4 and IPv6 products are engineered for smooth integration and low run-time overhead to address the challenges faced by embedded system development teams in adding networking, security and management to low cost devices.
