Abstract:
IPsec/ESP secure every single IP packets exchanged between two nodes.
This makes security transparent to the applications, as opposed to
TLS or DTLS for example.
IPsec/ESP has not widely been used to secure application because
IPsec is implemented in the kernel space, and IPsec/ESP security
rules are defined on the device -- similarly to firewall. In
addition, IPsec/ESP introduces network overhead on an IP packet
basis, as opposed as TLS/DTLS that introduces network overhead on an
UDP or TCP segment basis. This mostly impacts devices that do not
perform IP fragmentation.
Such drawbacks are not anymore valid for IoT, and the IPsec/ESP may
even better fits IoT usage and security requirements. IoT device are
usually hardware dedicated for a given task or a given application
which makes Kernel / user land split less significant. IoT devices
send data that is most likely expected to fit in a single IP packet.
Eventually, configuring IPsec/ESP security rules provides the ability
to enforce the security of the device, as security is not handled on
a per-application basis. Then the database structure of the IPsec/
ESP security policies perfectly match sleeping nodes.
This document defines Diet-ESP that adapts IPsec/ESP for IoT. The
goal of Diet-ESP is to reduce the size of the IPsec/ESP packet sent
on the wire. As a result Diet-ESP is expected to compress
traditional IPsec/ESP packet without impacting the security provided
by IPsec/ESP.
