Architect supports a unified methodology for specifying , compiling,
and verifying full-chip test. Mocana software is designed
with ease of install and use in mind:

Simple and easy-to-use API -- ease of use and ease of
installation built in from the start

All the complexity of cryptography is hidden; no deep domain
knowledge is needed

Multiple cryptographic algorithms supported; maximum security
available

Mocana Embedded SSH Client

The Mocana Embedded SSH Client is small footprint, high
performance software that resides on a device to allow secure Telnet
communications between a device and any other device or back end SSH
management console or SFTP Server.

-- No operating system required

-- Full source code license

Mocana RADIUS Client

The Mocana RADIUS Client implements a client/server mechanism that
enables devices to communicate with a central server to authenticate
users and authorize their access to the requested system or service.

Features

Fully compliant and fully featured

-- RFC compliant, interoperability tested

-- Supports RADIUS accounting

-- Includes password-based authentication client

-- Built-in authentication with PAP, CHAP

-- Supports challenge-response

-- Dynamic shutdown and restart

-- Can be used stand alone or with network security protocols
