This draft is a work item of the Trusted Execution Environment Provisioning WG of the IETF. Title : HTTP Transport for Trusted Execution Environment Provisioning: Agent-to- TAM Communication Author : Dave Thaler Filename : draft-ietf-teep-otrp-over-http-03.txt Pages : 14 Date : 2019-11-04 Abstract: The Trusted Execution Environment Provisioning (TEEP) Protocol is used to manage code and configuration data in a Trusted Execution Environment (TEE). This document specifies the HTTP transport for TEEP communication where a Trusted Application Manager (TAM) service is used to manage TEEs in devices that can initiate communication to the TAM. An implementation of this document can (if desired) run outside of any TEE, but interacts with a TEEP implementation that runs inside a TEE.

Hi all,

 

in time for the deadline I have submitted draft-tsch= ofenig-teep-protocol-00, which replaces draft-tschofenig-teep-otrp-v2-00.

 

At the last IETF meeting we had a discussion about t= he name of the protocol (which I called OTrPv2) and the potential confusion= it could cause in relationship to Global Platform. As discussed on the lis= t I changed the name and aligned terminology throughout the document.

 

I am hoping to spend some time with folks at the upc= oming Hackathon & IETF meeting to further refine the content and to do = some implementation work.

 

Ciao

Hannes

This draft is a work item of the Trusted Execution Environment Provisioning WG of the IETF. Title : Trusted Execution Environment Provisioning Protocol (teep-p) Authors : Hannes Tschofenig Mingliang Pei David Wheeler Dave Thaler Filename : draft-tschofenig-teep-protocol-01.txt Pages : 20 Date : 2019-11-17 Abstract: This document specifies a protocol that installs, updates, and deletes Trusted Applications (TAs) in a device with a Trusted Execution Environment (TEE). This specification defines an interoperable protocol for managing the lifecycle of TAs. The protocol name is teep-p, pronounced teepee. This conjures an image of a wedge-shaped protective covering for one's belongings, which sort of matches the intent of this protocol.

The STM has 32-Gbit eMMC for rootfs while Grapeboard have to use SD card for rootfs. The Grapeboard have commonly used rootfs such as, Ubuntu and Yocto based Li= nux. I will look into them. -Akira On Tue, Nov 19, 2019 at 10:16 AM Dave Thaler wrote: > > During the WG session today, in the discussion of potential hardware for = future hackathons, I recommended the Grapeboard: > > https://www.grapeboard.com/ > > This is an NXP Cortex A53 based board. > > > > That=E2=80=99s the board that=E2=80=99s used in the commercial Scalys Tru= stbox routers: > > https://scalys.com/trustbox-home-router/ > > which is the device that got the cybersecurity innovation award at CES 20= 19: > > https://www.techrepublic.com/article/ces-2019-innovation-awards-honoree-t= rustbox-iot-security-router/ > > > > Dave > > _______________________________________________ > TEEP mailing list > TEEP@ietf.org > https://www.ietf.org/mailman/listinfo/teep From nobody Wed Nov 27 01:53:54 2019 Return-Path: X-Original-To: teep@ietfa.amsl.com Delivered-To: teep@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 44CAB120832 for ; Wed, 27 Nov 2019 01:53:52 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.999 X-Spam-Level: X-Spam-Status: No, score=-1.999 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, FREEMAIL_FROM=0.001, RCVD_IN_DNSWL_NONE=-0.0001, SPF_HELO_NONE=0.001, SPF_PASS=-0.001] autolearn=ham autolearn_force=no Authentication-Results: ietfa.amsl.com (amavisd-new); dkim=pass (2048-bit key) header.d=gmail.com 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 4EQFeP0SMKfy for ; Wed, 27 Nov 2019 01:53:50 -0800 (PST) Received: from mail-wr1-x42c.google.com (mail-wr1-x42c.google.com [IPv6:2a00:1450:4864:20::42c]) (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 197B81200F7 for ; Wed, 27 Nov 2019 01:53:50 -0800 (PST) Received: by mail-wr1-x42c.google.com with SMTP id b18so25875421wrj.8 for ; Wed, 27 Nov 2019 01:53:50 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=mime-version:references:in-reply-to:from:date:message-id:subject:to :cc:content-transfer-encoding; bh=a9hs7YfTgPd8QabmE9mTQ684znx89qsylnYjH5fAzkA=; b=t9yif4CFU1c0dqG6ZlWhj21dCXhmvCpSFL28GE80ynI5Ik591/vmJf4O08rcUNaAdO nPkkKxn3bN1oGTep6k/kSkfa57MUQor7zg58icnP+l83t9+z0XZQxGgqcY/8A7PkYU0u ZKlCIIwmgPjPf/ncYYbaLU5J8qhF//+cUlq2rYPzkDEK5ks6qMEU/utPX/r5RFhkfTa8 o9Mc+uRZFpq3atkT/HwZhFPWnrZstWIJNAXxxgYlEvqXyFSngGug6jiZXxqLvOHujSZp GUrVIadayYxq4nDFtuBU0noRhtFfsiTAKeIQpm/r3h8N5f16K5S+YYXyD8wxQltM63nZ +OXA== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:mime-version:references:in-reply-to:from:date :message-id:subject:to:cc:content-transfer-encoding; bh=a9hs7YfTgPd8QabmE9mTQ684znx89qsylnYjH5fAzkA=; b=rYTvsH3lmhY/JEyRHY7iF46c6Sg2i1O55hTGJMTFqmJMfUc6vv8B2gHYBmhI2AUvwo 4rDjjIub3lTYzNHUOEDnWyAuNQ2moY83ydJLQXWxjTDikq44NniVbpq4dSJUG7rEezvq Lk0Mgl2cyH8a/4/MIv7o9KLSif8ZS8JgwZbm3o6uJYEwp68Eod1sU9lcFaRplXMKfL01 B0YKeenQT4bOx4kkpxuSpVlMclVfEB1gQUrmzTqg4u/1m1ufj3833e/rCxhAf+w45FAW dKYoGEXYrxEWMI2+X0e2aYz0GeY++4eU5eEBm3/1pQel9FaRctIImPerE0ACe1Tg+qJR qnYQ== X-Gm-Message-State: APjAAAWfsLpasG6kMWGzFGvfVNPFdxe5N+uptzU6jT0zhVCqFGAMGkyF 6AFv5Vf0XCsU2espPPIIe+fjdUJTQInAzy9VPSo= X-Google-Smtp-Source: APXvYqyWNFQ4XM66zP2jOPAu3RSxYmlay13LKHh4EtkQcAn6GxFtfMEa90Ca25YzcGVD97+dsMpwQIa5mebKpWTSmLM= X-Received: by 2002:adf:e550:: with SMTP id z16mr18333204wrm.315.1574848428391; Wed, 27 Nov 2019 01:53:48 -0800 (PST) MIME-Version: 1.0 References: In-Reply-To: From: Akira Tsukamoto Date: Wed, 27 Nov 2019 18:53:36 +0900 Message-ID: To: Dave Thaler Cc: "teep@ietf.org" , Hannes Tschofenig , Isobe Kohei Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Archived-At: Subject: Re: [Teep] Hardware for hackathons X-BeenThere: teep@ietf.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: A Protocol for Dynamic Trusted Execution Environment Enablement List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 27 Nov 2019 09:53:52 -0000 Hi Dave, Hannes and Isobe-san, For the further discussion for the future hackathon, I searched information of Grapeboard and STM32MP157C-DK2 (which is STM CortexA7 devboard, I will abbreviate as StmA7board). It is not mandatory but it would be nice to have/use unified programing software stacks for the TEEP development on both TAM and TEEP device. I briefly mentioned about it on page 14 in the slide at IETF106. https://datatracker.ietf.org/meeting/106/materials/slides-106-teep-sessb-te= ep-hackathon-report Also, I looked inside the Dave`s OTrP over http implementation. https://github.com/dthaler/OTrP I have listed items for a discussion of the choices which were based on what we used at the ietf106 hackathon. Dave and Isobe-san, please correct me if I am wrong. :) *) JSON stack: (1) jansson, which Dave is using https://github.com/akheron/jansson (2) node.js, Isobe-san`s TAM (3) json parser in libwebsockets, which my prototype is using https://github.com/warmcat/libwebsockets/tree/master/lib/jose *) JOSE stack: (1) latchset/jose, which Dave is using https://github.com/latchset/jose (2) node.js?, Isobe-san`s TAM (3) libwebsockets *) HTTP stack: (1) from scratch?, In Dave`s https://github.com/dthaler/OTrP/blob/master/TeepTamBrokerLib/HttpServer.cpp (2) libwebsockets, In mine *) Crypto-tsl stack: (1) openssl, Dave`s (2) mbedtls, mine Other than above, might good to use smaller libs, wolfSSL or s2n on the device side? *) rootfs (1) Ubuntu?, Dave`s (2) buildroot, mine The default rootfs of dev boards introduced by Dave and Hannes. *) Grapeboard Ubuntu, customizable to Yocto/OE, OpenWRT and etc *) StmA7board Yocto/OE (OpenSTLinux) Also, we have to consider the hardware requirements of SGX, ARM TrustZone and RISC-V too. The SGX is pretty handy since it could use simulation mode on any pc. The op-tee is able to run on qemu too. For the dev board, cross compiling is used so what to do on host pc, Linux pc with ubuntu, win and etc. And it would be really nice to have docker image for the dev environment which includes necessary software stacks for developing teep/otrp at least for developing TAM side. The TAM and TEEP device do not have to be using the same software stacks listed above. I honestly do not have any preference listed above. I was late on the boat and did not know what others have done in the past. We do not have so much engineering resources at the moment, so I thought it would be good to work on similar environment as possible to able to focus on teep stack.

I will admit that I'm struggling a bit to understand the value of an interop hackathon where everyone is using the same software. I see the point for a tutorial on a particular stack. (I also come at this from the RATS point of view, of soft TPMs running in TEEs, and also TEEs attesting to relying parties rather than other TEE applications) I also see a point in helping people who are building other components in the ecosystem to learn how to bring up the things that they are intending to interoperate with. > *) JSON stack: > (1) jansson, which Dave is using > https://github.com/akheron/jansson > (2) node.js, Isobe-san`s TAM > (3) json parser in libwebsockets, which my prototype is using > https://github.com/warmcat/libwebsockets/tree/master/lib/jose > *) JOSE stack: > (1) latchset/jose, which Dave is using > https://github.com/latchset/jose > (2) node.js?, Isobe-san`s TAM > (3) libwebsockets > *) HTTP stack: > (1) from scratch?, In Dave`s > https://github.com/dthaler/OTrP/blob/master/TeepTamBrokerLib/HttpServer.cpp > (2) libwebsockets, In mine > *) Crypto-tsl stack: > (1) openssl, Dave`s > (2) mbedtls, mine > Other than above, might good to use smaller libs, wolfSSL or s2n on > the device side? > *) rootfs > (1) Ubuntu?, Dave`s > (2) buildroot, mine This is a wide variety of options, and this is great!
