Abstract:
IPsec/ESP has been designed to secure IP packets exchanged between
two nodes. IPsec implements security at the IP layer which makes
security transparent to the applications, as opposed to TLS or DTLS
that requires application to implement TLS/DTLS. As a result, IPsec
enable to define the security rules in a similar way one establishes
firewall rules.
One of the IPsec's drawbacks is that implementing security on a per
packet basis adds overhead to each IP packet. Considering IoT
devices, the data transmitted over an IP packet is expected to be
rather small, and the cost of sending extra bytes is so high that
IPsec/ESP can hardly be used for IoT as it is currently defined in
RFC 4303.
This document defines Diet-ESP, a protocol that compress and reduce
the ESP overhead of IPsec/ESP so that it can fit security and energy
efficient IoT requirements. Diet-ESP use already existing mechanism
like IKEv2 to negotiate the compression format. Furthermore a lot of
information, already existing for an IPsec Security Association, are
reused to offer light negotiation in addition to maximum compression.
