Hi all, Please find a draft we have just posted. It is updated with some of the comments from the mailinglist and moved from dice to ipsecme WG.
Comments are welcome, A new version of I-D, draft-mglt-ipsecme-diet-esp-00.txt has been successfully submitted by Tobias Guggemos and posted to the IETF repository. Name: draft-mglt-ipsecme-diet-esp Revision: 00 Title: Diet-ESP: a flexible and compressed format for IPsec/ESP Document date: 2014-03-03 Group: Individual Submission Pages: 26 URL: <http://www.ietf.org/internet-drafts/draft-mglt-ipsecme-diet-esp-00.txt> http://www.ietf.org/internet-drafts/draft-mglt-ipsecme-diet-esp-00.txt Status: <https://datatracker.ietf.org/doc/draft-mglt-ipsecme-diet-esp/> https://datatracker.ietf.org/doc/draft-mglt-ipsecme-diet-esp/ Htmlized: <http://tools.ietf.org/html/draft-mglt-ipsecme-diet-esp-00> http://tools.ietf.org/html/draft-mglt-ipsecme-diet-esp-00 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. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
