The RFC8152 describes as: COSE_Mac_Tagged = #6.97(COSE_Mac) COSE_Sign_Tagged = #6.98(COSE_Sign) COSE_Mac0_Tagged = #6.17(COSE_Mac0) COSE_Sign1_Tagged = #6.18(COSE_Sign1) and I was confused with the #6 and the brackets on the right side. After reading the implementation of tinycbor and IANA, Tinycbor https://github.com/intel/tinycbor/blob/master/src/tags.txt IANA https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml probably it is COSE_Mac_Tagged = #6.97(COSE_Mac) means that CBOR Tag is 97 and uses COSE_Mac = [ Headers, payload : bstr / nil, tag : bstr, recipients :[+COSE_recipient] ] and the examples is, 97( [ / protected / h'a1010f' / { \ alg \ 1:15 \ AES-CBC-MAC-256//64 \ } / , / unprotected / {}, / payload / 'This is the content.', / tag / h'9e1226ba1f81b848', / recipients / [ [ / protected / h'', / unprotected / { / alg / 1:-6 / direct /, / kid / 4:'our-secret' }, / ciphertext / h'' ] ] ] ) Thanks, -Akira On 4/9/20 12:45, Jim Schaad wrote: > These values are defined in RFC 8152, draft-ietf-cose-rfc8152bis-struct or > in the IANA registry. > > Jim > > > -----Original Message----- > From: Suit On Behalf Of Akira Tsukamoto > Sent: Wednesday, April 8, 2020 6:59 PM > To: suit@ietf.org > Subject: [Suit] Value of > COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged > > Hi all, > > I am not sure this is the right place to ask. > > This is the feedback from the TEEP-wg after the virtual hackathon and > interim meeting. > > TEEP was using > COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged. > Are these tags defined the value in some drafts or iana? > When we were trying to implement the teep, we could not put the bstr or > int/uint for the tags. > > I the draft-ietf-suit-manifest-01, it also using these tags in page 43, > https://jpn01.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftools.ietf.org%2Fhtml%2Fdraft-ietf-suit-manifest-01&data=02%7C01%7Cakira.tsukamoto%40aist.go.jp%7Cdddac6fb0a33483c20b308d7dc387820%7C18a7fec8652f409b8369272d9ce80620%7C0%7C0%7C637220007412654750&sdata=knhFlGCBf5M1hwal1kdnGXinEa2ROXc7cxau7GN5uOs%3D&reserved=0 > > as > > SUIT_Authentication_Wrapper = [ + ( > COSE_Mac_Tagged / > COSE_Sign_Tagged / > COSE_Mac0_Tagged / > COSE_Sign1_Tagged) > ] > > COSE_Mac_Tagged = any > COSE_Sign_Tagged = any > COSE_Mac0_Tagged = any > COSE_Sign1_Tagged = any > > It was deleted in teep at the link bellow of the pull request after the > discussion from the hackathon, > https://jpn01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fietf-teep%2Fteep-protocol%2Fcommit%2F151e72b0ea3ab8ff8f59ea4200&data=02%7C01%7Cakira.tsukamoto%40aist.go.jp%7Cdddac6fb0a33483c20b308d7dc387820%7C18a7fec8652f409b8369272d9ce80620%7C0%7C0%7C637220007412654750&sdata=QDJd5wiBo6p2c3Z0qc9eWvKbVBkO0kA%2FhmwCcxf1O%2FU%3D&reserved=0 > 4180d90006f8c9 > but would be nice to know if it was OK with similar bellow, > > COSE_Mac_Tagged = 1 > COSE_Sign_Tagged = 2 > COSE_Mac0_Tagged = 3 > COSE_Sign1_Tagged = 4 > > Thanks, > -Akira > > _______________________________________________ > Suit mailing list > Suit@ietf.org > https://jpn01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ietf.org%2Fmailman%2Flistinfo%2Fsuit&data=02%7C01%7Cakira.tsukamoto%40aist.go.jp%7Cdddac6fb0a33483c20b308d7dc387820%7C18a7fec8652f409b8369272d9ce80620%7C0%7C0%7C637220007412654750&sdata=e3YPByN13RYRMDIturl6CD5D3wue1cFaHntsxh115RQ%3D&reserved=0 > From nobody Thu Apr 9 01:40:27 2020 Return-Path: X-Original-To: suit@ietfa.amsl.com Delivered-To: suit@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 550EC3A0F04 for ;

I posted a PR with the new CDDL at https://github.com/ietf-teep/teep-protoc= ol/pull/26 Ciao Hannes -----Original Message----- From: Suit On Behalf Of Akira Tsukamoto Sent: Thursday, April 9, 2020 8:54 AM To: Jim Schaad ; suit@ietf.org Subject: Re: [Suit] Value of COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tag= ged/COSE_Sign1_Tagged Hi Jim, I think I started figure out what was going on. The RFC8152 describes as: COSE_Mac_Tagged =3D #6.97(COSE_Mac) COSE_Sign_Tagged =3D #6.98(COSE_Sign) COSE_Mac0_Tagged =3D #6.17(COSE_Mac0) COSE_Sign1_Tagged =3D #6.18(COSE_Sign1) and I was confused with the #6 and the brackets on the right side. After reading the implementation of tinycbor and IANA, Tinycbor https://github.com/intel/tinycbor/blob/master/src/tags.txt IANA https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml probably it is COSE_Mac_Tagged =3D #6.97(COSE_Mac) means that CBOR Tag is 97 and uses COSE_Mac =3D [ Headers, payload : bstr / nil, tag : bstr, recipients :[+COSE_recipient] ] and the examples is, 97( [ / protected / h'a1010f' / { \ alg \ 1:15 \ AES-CBC-MAC-256//64 \ } / , / unprotected / {}, / payload / 'This is the content.', / tag / h'9e1226ba1f81b848', / recipients / [ [ / protected / h'', / unprotected / { / alg / 1:-6 / direct /, / kid / 4:'our-secret' }, / ciphertext / h'' ] ] ] ) Thanks, -Akira On 4/9/20 12:45, Jim Schaad wrote: > These values are defined in RFC 8152, > draft-ietf-cose-rfc8152bis-struct or in the IANA registry. > > Jim > > > -----Original Message----- > From: Suit On Behalf Of Akira Tsukamoto > Sent: Wednesday, April 8, 2020 6:59 PM > To: suit@ietf.org > Subject: [Suit] Value of > COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged > > Hi all, > > I am not sure this is the right place to ask. > > This is the feedback from the TEEP-wg after the virtual hackathon and > interim meeting. > > TEEP was using > COSE_Mac_Tagged/COSE_Sign_Tagged/COSE_Mac0_Tagged/COSE_Sign1_Tagged. > Are these tags defined the value in some drafts or iana? > When we were trying to implement the teep, we could not put the bstr > or int/uint for the tags. > > I the draft-ietf-suit-manifest-01, it also using these tags in page > 43, > https://jpn01.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Ftool > s.ietf.org%2Fhtml%2Fdraft-ietf-suit-manifest-01&data=3D02%7C01%7Caki > ra.tsukamoto%40aist.go.jp%7Cdddac6fb0a33483c20b308d7dc387820%7C18a7fec > 8652f409b8369272d9ce80620%7C0%7C0%7C637220007412654750&sdata=3DknhFl > GCBf5M1hwal1kdnGXinEa2ROXc7cxau7GN5uOs%3D&reserved=3D0 > > as > > SUIT_Authentication_Wrapper =3D [ + ( > COSE_Mac_Tagged / > COSE_Sign_Tagged / > COSE_Mac0_Tagged / > COSE_Sign1_Tagged) > ] > > COSE_Mac_Tagged =3D any > COSE_Sign_Tagged =3D any > COSE_Mac0_Tagged =3D any > COSE_Sign1_Tagged =3D any > > It was deleted in teep at the link bellow of the pull request after > the discussion from the hackathon, > https://jpn01.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fgith > ub.com%2Fietf-teep%2Fteep-protocol%2Fcommit%2F151e72b0ea3ab8ff8f59ea42 > 00&data=3D02%7C01%7Cakira.tsukamoto%40aist.go.jp%7Cdddac6fb0a33483c2 > 0b308d7dc387820%7C18a7fec8652f409b8369272d9ce80620%7C0%7C0%7C637220007 > 412654750&sdata=3DQDJd5wiBo6p2c3Z0qc9eWvKbVBkO0kA%2FhmwCcxf1O%2FU%3D > &reserved=3D0 > 4180d90006f8c9 > but would be nice to know if it was OK with similar bellow, > > COSE_Mac_Tagged =3D 1 > COSE_Sign_Tagged =3D 2 > COSE_Mac0_Tagged =3D 3 > COSE_Sign1_Tagged =3D 4 > > Thanks, > -Akira > > _______________________________________________ > Suit mailing list > Suit@ietf.org > https://jpn01.safelinks.protection.outlook.com/?url=3Dhttps%3A%2F%2Fwww. > ietf.org%2Fmailman%2Flistinfo%2Fsuit&data=3D02%7C01%7Cakira.tsukamot > o%40aist.go.jp%7Cdddac6fb0a33483c20b308d7dc387820%7C18a7fec8652f409b83 > 69272d9ce80620%7C0%7C0%7C637220007412654750&sdata=3De3YPByN13RYRMDIt > url6CD5D3wue1cFaHntsxh115RQ%3D&reserved=3D0 > _______________________________________________ Suit mailing list Suit@ietf.org https://www.ietf.org/mailman/listinfo/suit IMPORTANT NOTICE: The contents of this email and any attachments are confid= ential and may also be privileged.

When I was reading the cddl draft, I was not quite sure how to describe the array with the label name. In your pull request, query-request =3D [ type: TEEP-TYPE-query-request, token: uint, The above cddl description has label name type and token with semicolon. We were trying to avoid having label name inside the array. I thought I have to use =3D> for this purpose. Other discussion we had with the teep is to use the same nonce as the EAT defines. nonce =3D> bytes, to be nonce =3D> bstr .size (8..64) And the size of token we never really agreed about it. How bout token: uint .size 4 The 32bit unsign integer seems to be reasonable for the usage in teep.

It is not transferred over "the wire", so we did not bother to define a corresponding type. In other words, you could simply omit "type: " and "token: " and nothing would change. It is annotation for humans, basically.

The discussion started between the Hackathon in Singapore and Berlin. This is the link to the github. https://github.com/ietf-teep/teep-protocol/issues/4 After going though again, I started to have my preference. The usage of TA_ID in TEEP message is to distinguish the required TA in the device by parsing of identification id. The it will be good to be able to match the TA with one bstr for one TA. I started to think hash value might work. Using the hash value from the properties of Parameters in Section 5.4.1 in SUIT CBOR Manifest for each TA. The generating hash from adding all the properties. These are the requited parameters. - Vendor ID. - Class ID. # Could be file name for SGX, uuid for op-tee. uuid is used as file name in op-tee anyway - Image Digest. # This is version of TA It is up to the user who would like to add optional parameters for the seed. We have to consider which hash function to use too, and easiest to come up is probably sha256. The hash value of sha256 is 32 bytes which is still going to be second largest member than NONCE in TEEP message. I prefer smaller bytes to reduce the teep message size but raw parameters of all three above would be larger than 32bytes, so it may be acceptable. The purpose of the hash value here is mainly for prevent colliding between different TAs or different version in the TAM server. -Akira From nobody Fri Apr 24 01:55:55 2020 Return-Path: X-Original-To: suit@ietfa.amsl.com Delivered-To: suit@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 8B9473A10D4 for ; Fri, 24 Apr 2020 01:55:45 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.395 X-Spam-Level: X-Spam-Status: No, score=-1.395 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, FREEMAIL_FORGED_FROMDOMAIN=0.25, FREEMAIL_FROM=0.001, HEADER_FROM_DIFFERENT_DOMAINS=0.25, HTML_MESSAGE=0.001, RCVD_IN_MSPIKE_H3=0.001, RCVD_IN_MSPIKE_WL=0.001, SPF_HELO_NONE=0.001, SPF_PASS=-0.001, URIBL_BLOCKED=0.001] autolearn=no autolearn_force=no Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Ha_ArxLyXC50 for ; Fri, 24 Apr 2020 01:55:43 -0700 (PDT) Received: from mail-ot1-f50.google.com (mail-ot1-f50.google.com [209.85.210.50]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id 84FBF3A10E0 for ; Fri, 24 Apr 2020 01:55:37 -0700 (PDT) Received: by mail-ot1-f50.google.com with SMTP id i27so11134515ota.7 for ; Fri, 24 Apr 2020 01:55:37 -0700 (PDT) X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:from:date:message-id:subject:to; bh=nInhwFlFspevVfO6Iq8eEJYLs0l40Gls6KQow43QH8I=; b=h1YwUo2CstWSVcrWlprTGbgJSxQUf+xyOCKJNmvHjbUhHouiR3v5JuQZGPJcn1jKt+ S258gEtwowgH2kHf0XGCkbDSW7hCPIPZDH2pEgxbP7+x9FpAHPpVzuXs+VK9meaGEzSm Khqqa6aJ8MJDygtEspWKSivFxmsAF8qIr5lAejZtGbxx8hKmVnXisTYNj89+4LC4+jHI PMZj+Sek9J0OHhbgnqUnU/XCnfTSL9uBIAF77GifVibQVmnBjXLenbacky6IorjQT5V7 8iKwnFDpDRDrJp8uAZk90I+N52fx3e38+2LUHRL1Xy3z8isAgJoLpS7+CTEBiyogg4mu Q36g== X-Gm-Message-State: AGi0PubODd+23LhJKPre2kv62qE/Dio6z+5sp8hW9edNTVKpbo3IyVhI JXin8Jxsok2WULrGPuaktz7/m1MVf9PaX2dn8Pg0M3NSxLo= X-Google-Smtp-Source: APiQypJ4JIjwqS8hG25T0MVnhi1NBId0RGify2oVRNTgAYLZz8aFfZLmOhDCu9/74HOofRyL8V6zIJiYuLoTOxYKtLI= X-Received: by 2002:aca:ad87:: with SMTP id w129mr5912442oie.173.1587718536616; Fri, 24 Apr 2020 01:55:36 -0700 (PDT) MIME-Version: 1.0 From: Emmanuel Baccelli Date: Fri, 24 Apr 2020 10:55:25 +0200 Message-ID: To: suit Content-Type: multipart/alternative; boundary="00000000000060e03905a4058779" Archived-At: Subject: [Suit] RIOT Summit 2020: Call for contributions X-BeenThere: suit@ietf.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Software Updates for Internet of Things List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 24 Apr 2020 08:55:53 -0000 --00000000000060e03905a4058779 Content-Type: text/plain; charset="UTF-8" Dear all, as RIOT provides an open source implementation of SUIT, the below call for contributions might be of interest for you.
