Application note

Transport layer security protocol for SPWFxxx module

Introduction

The purpose of this document is to present a demonstration package for creating a secure

connection over TCP/IP between the Wi-Fi module SPWF01Sxxx (see [1] in

References)and a remote server exposing secured service.

Security is provided by the secure sockets layer (SSL) and transport layer security (TLS)

protocols. The SSL/TLS protocols provide security for communication over networks, such

as the Internet, and allow client and server applications to communicate in a way that is

confidential and secure.

The document includes a brief introduction to SSL/TLS principles, a description of the

demonstration package organization and a tutorial with client-server connection examples.
