IPsec solves an important problem which arises when embedded systems
are connected to the Internet. Since the Internet protocol has no
data security built-in, both application and user data is sent in
clear text. This enables a third party to inspect or even modify
data from the embedded system as it traverses the Internet. For
example, passwords are sent in the open and can be seen and used
to compromise a system.
Adding IPsec to an embedded system will take care of these threats
because IPsec includes strong encryption, integrity, authentication
and replay protection. IPsec has become the de facto standard for
creating secure networks, and is supported by all major network
vendors.
Interpeak IPsec is designed for both IPv4 and IPv6 operation, and
is optimized for deployment in embedded systems. It is delivered
in ANSI compliant C source code, with ready-to-run RTOS integration
containing makefiles etc.
