Interpeak VPN is a software package that protects all networking
applications in your embedded system from security threats. This
is done by creating a Virtual Private Network, i.e. a secure connection
over an insecure network. Interpeak VPN is based on industry-standard
IPsec technology, and consists of Interpeak IPsec and Interpeak
IKE. IPsec provides strong encryption, integrity, authentication
and replay protection while IKE is used for secure key distribution.
IPsec is a versatile security solution because it can perform different
security mechanisms. Authentication is used to certify that a packet
originates from the correct sender, encryption to ensure data content
confidentiality, integrity to make sure that the packets have not
been modified in transit and replay protection to stop duplication
of old transactions. Since IPsec is applied on the IP level, all
IP based protocols are protected. This makes it possible to add
security to an existing system, without having to change a single
line of application code.
IKE is a key distribution protocol that is designed to cooperate
with IPsec. IKE manages negotiation of the security characteristics
on the different types of communication. Especially large systems
will benefit from using Interpeak IKE. When the number of nodes
increases, manual configuration becomes unfeasible. In such large
systems, Interpeak IKE is typically deployed to automatically handle
the key configuration and exchange.
