[IPsec] ChaCha20 + Poly1305 for IKE and IPsec

[Yoav Nir <[e-mail]>]

Hi

A little over a year ago I proposed to define the ChaCha20 cipher and Poly1305 authenticators for IKE and IPsec both as standalone documents and as an AEAD. At the same time Adam Langley proposed the same to the TLS working group.

We were told two things: First, the groups preferred only the AEAD, and second, we were requested to get CFRG’s stamp of approval.

This resulted in a CFRG document defining the algorithms, and offering implementation advice and test vectors. This document has just been approved and has been sent to the RFC editor [1].

In the meantime, I have updated my draft to only define the AEAD. Since we not have CFRG’s “stamp of approval” if not yet an RFC number, I would like to renew my request to have the ChaCha20+Poly1305 for IKE and IPsec document [2] accepted by this working group with the intent of having it published as a standard-track document.

Thanks

Yoav
