Message-ID: <CAGiyFdfBSNLqdLy32ZtWV5xZoecESc=S8F5r0q-oV4679P9FQg@mail.gmail.com> Date: Tue, 9 Dec 2014 15:38:54 +0100 From: Jean-Philippe Aumasson <jeanphilippe.aumasson@...il.com> To: discussions@...sword-hashing.net Subject: PHC finalists tweaks (SUBMITTERS, please read carefully) As announced yesterday the PHC panel selected 9 finalists: Argon, battcrypt, Catena, Lyra2, Makwa, Parallel, POMELO, Pufferfish, yescrypt. Finalists are an intermediate shortlist before the final selection of one or more winners around Q2 2015. Submitters of a finalist are now given a chance to make minor changes to their algorithm: Submitters have until January 31, 2015 to submit the final version of their algorithm. If the final version is identical to the current version, submitters don't need to send anything. If the final version differs from the current version, submitters should send an email to submissions@...sword-hashing.net including: * a revised submission package (including updated specs and reference implementation); either as an attachment or as a URL * a description of the tweak proposed and some rationale for this tweak The panel will examine the proposed tweak and will then respond whether or not the final version of the algorithm is accepted. There's no formal definition of an acceptable tweak, but we plan to accept any change that does not change fundamentally the algorithm. For example, the tweak may consist in replacing BLAKE2 by SHA-512 as a core primitive; in replacing a XOR by an ADD in some internal algorithm; in changing the number of rounds of some function from 10 to 12; etc. We also encourage submitters to polish the submission document and the reference implementation of their algorithm. The clearer and the more convincing, the easier it will be for the panel to understand the merits of the algorithm and to assess it fairly against other submissions. Inquiries to the panel may be addressed to this (public) mailing list, or to the private distribution list panel@...sword-hashing.net. Thank you!
