Overview

The supplicant is a LAN port that requests access to the services that are accessed through the authenticator for wireless or wired connections.

Satyav Networks provides an IEEE 802.1x based software used in the client station.

For example laptops, personnel computers, embedded wireless devices etc.

Satyav’s Supplicant modules can be run on any wireless or wireless client station or can be integrated with any hardware or OS platform.

Satyav’s supplicant stack is currently integrated with latest EAP methods like MD5, TLS and PEAP and because of it's modular design it is easy to extent with any new EAP methods. It also supports framework for 802.11i and WEP key management.

Supplicant can be used by OEM, network devices manufactures and embedded devices. Stack is available in source as well as binary form. Following figure shows the Satyav’s supplicant role in 802.1x based Authentication process.

Currently stack is running on Linux and can be easily portable on any operating system. It's modular design and operation specific libraries makes easy to port on any platform. Demo version as well as sample code is available on request.

Satyav’s WiSupplicant Architecture

Highlights of the stack

• Stack written in C and C++.

• Runs on Linux, Windows, capable to run on embedded environment and easily portable on any platform. 

• Multi layered and structured modular design architectures.

• Configurable role and configurable debug.

• SUPPLICANT can be used as DLL, shared library or main application.

• Extensive error handling to the application.

• Test cases and Test Programs are ready to use.

• Using Satyav Network’s WiSSL as SSL library

• Operating system specific Libraries, i.e transmit, receive. timer, thread, packet management etc. are used.
