One of the questions is: who creates or assigns an ID= as the TA_ID to a TA?

A TAM is responsible to ins= tall, upgrade, or delete a TA. It may give it an identifier to track it. Di= fferent versions of TAs may use the same TA ID but add a version convention= . This allows a TAM to identify a TA for upgrade.

= To ensure uniqueness, a UUID is a good choice for a TA ID where a TAM may c= reate to be unique.

Should the TA developer create= and provide TA ID to the downstream systems? It can but I think a TAM may = override it if it needs to do so. The TA developer should define a friendly= display name for the TA. When a TAM manages many TAs, a TAM operator will = like to see friendly display names rather than the opaque TA IDs that are c= reated for machine consumption. A TAM may locally maintain a mapping betwee= n TA names and TA IDs.

With SUIT compatibility= , a UUID Component ID for TA ID can work. Is there a place holder in SUIT f= or a TA friendly name? A TA name doesn't need to be passed to the TEEs = for management; it may help debugging logging but may not be worthy of the = bandwidth and size cost.

Hi all,

I would like to restart the discussion of Unique Identifier of TA_ID in TEE= P's QueryResponse which was one of the item came up at TEEP interim mee= ting last week.

The discussion started between the Hackathon in Singapore and Berlin.

This is the link to the github.
https://clicktime.symantec.com/38kWqaWA3sW14euWC= DuBdWf7Vc?u=3Dhttps%3A%2F%2Fgithub.com%2Fietf-teep%2Fteep-protocol%2Fissues= %2F4

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.

=C2=A0 =C2=A0 -=C2=A0 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 larg= est member than NONCE in TEEP message.
I prefer smaller bytes to reduce the teep message size but raw parameters o= f 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.

2020 11:19:48 -0000 Hi What I was thinking of images similar to the pseudocode bellow. typedef struct { uint16_t vender_id; /* RFC4112, type5, 128 bit, 16 byte */ uint16_t class_id; /* RFC4112, type5, 128 bit, 16 byte */ uint16_t device_id; /* device unique-ID, 128 bit, 16 byte */ } teep_uid_t; digest[MDSIZE]; teep_uid_t uid; sha256_ctx_t ctx; uint32_t hash_uid; /* 256 bit */ memset(digest, 0, sizeof(digest)); memset(&uid, 0, sizeof(uid)); sha256_init(&ctx, MDSIZE); sha256_update(&ctx, &uid.vender_id, sizeof(uid.vender_id)); sha256_update(&ctx, &uid.class_id, sizeof(uid.class_id)); sha256_update(&ctx, &uid.device_id, sizeof(uid.device_id)); sha256_final(digest, &ctx); convert_d_uid(digest, hash_uid); Then use the hash_uid as TA_ID in the teep message. This way the TAM do not have to separately store the TAs with vender_id and/or class_id. And good definition of vender_id, class_id and device_id are in the suit manifest draft, therefor, we do not have to mention the details in teep drafts. We have to specify which sha256 or anything else to use. -Akira On 5/13/20 15:00, Mingliang Pei wrote: > One of the questions is: who creates or assigns an ID as the TA_ID to a TA? > > A TAM is responsible to install, upgrade, or delete a TA. It may give it an identifier to track it. Different versions of TAs may use the same TA ID but add a version convention. This allows a TAM to identify a TA for upgrade. > > To ensure uniqueness, a UUID is a good choice for a TA ID where a TAM may create to be unique. > > Should the TA developer create and provide TA ID to the downstream systems? It can but I think a TAM may override it if it needs to do so. The TA developer should define a friendly display name for the TA. When a TAM manages many TAs, a TAM operator will like to see friendly display names rather than the opaque TA IDs that are created for machine consumption. A TAM may locally maintain a mapping between TA names and TA IDs. > > With SUIT compatibility, a UUID Component ID for TA ID can work. Is there a place holder in SUIT for a TA friendly name?

Brendan suggested to use the Component ID and we would make recommendations regarding the construction and the uniqueness we would like to have. For example, we could say that the component id for a TA should be a UUID and the same TA binary would have the same UUID. Note that this component ID could subsequently also be used as a filename but we could also keep it separate. > > What do you think? > > Ciao > Hannes > > -----Original Message----- > From: TEEP > On Behalf Of Akira Tsukamoto > Sent: Monday, April 13, 2020 7:46 AM > To: teep >; suit@ietf.org > Subject: [Teep] Unique Identifier of TA_ID in TA_LIST for TEEP_QueryResponse > > Hi all, > > I would like to restart the discussion of Unique Identifier of TA_ID in TEEP's QueryResponse which was one of the item came up at TEEP interim meeting last week. > > The discussion started between the Hackathon in Singapore and Berlin. > > This is the link to the github. > https://clicktime.symantec.com/38kWqaWA3sW14euWCDuBdWf7Vc?u=https%3A%2F%2Fgithub.com%2Fietf-teep%2Fteep-protocol%2Fissues%2F4 > > 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 > > _______________________________________________ > TEEP mailing list > TEEP@ietf.org > https://clicktime.symantec.com/3bbx7gUqzexL4igHH5sBig7Vc?u=https%3A%2F%2Fwww.ietf.org%2Fmailman%2Flistinfo%2Fteep > IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

This draft is a work item of the Software Updates for Internet of Things WG of the IETF. Title : A Firmware Update Architecture for Internet of Things Authors : Brendan Moran Hannes Tschofenig David Brown Milosch Meriac Filename : draft-ietf-suit-architecture-09.txt Pages : 30 Date : 2020-05-22 Abstract: Vulnerabilities with Internet of Things (IoT) devices have raised the need for a solid and secure firmware update mechanism that is also suitable for constrained devices. Incorporating such update mechanism to fix vulnerabilities, to update configuration settings as well as adding new functionality is recommended by security experts. This document lists requirements and describes an architecture for a firmware update mechanism suitable for IoT devices. The architecture is agnostic to the transport of the firmware images and associated meta-data.

Title : A Concise Binary Object Representation (CBOR)-based Serialization Format for the Software Updates for Internet of Things (SUIT) Manifest Authors : Brendan Moran Hannes Tschofenig Henk Birkholz Koen Zandberg Filename : draft-ietf-suit-manifest-05.txt Pages : 94 Date : 2020-05-27 Abstract: This specification describes the format of a manifest. A manifest is a bundle of metadata about the firmware for an IoT device, where to find the firmware, the devices to which it applies, and cryptographic information protecting the manifest. Firmware updates and secure boot both tend to use sequences of common operations, so the manifest encodes those sequences of operations, rather than declaring the metadata. The manifest also serves as a building block for secure boot.

Hi all

 

I have just submitted version -05 of the SUIT manife= st draft.

 

I have re-arranged text in the draft quite a bit in = an attempt to improve clarity. Maybe it worked and maybe it didn’t.

 

It would be great if someone could re-read the docum= ent and tell me whether this new structure is an improvement.

 

Let me summarize what has changed (since the diff wi= ll not give you much insight):

 

  • The complete CDDL is now in the appendix
  • Examples are also in the appendix (and the source mat= erial has been uploaded to the repo)
  • Description of wh= at is mandatory to implement has been summarized in a chapter in the append= ix
  • Made an attempt to create an IANA consideration sec= tion with the CBOR-based value definitions.
  • Re-grouped the subsections explaining the manifest an= d I tried to use a more consistent naming
  • Moved some o= f the background text into the introduction
  • Checked th= e entire document for consistent naming of fields and terms
  • =
  • Removed the opcodes from the commands because they weren’t used= anywhere in the document
  • Added lots of references to = the section listing templates.
  • Created a dedicated “envelope” section to= describe the structure of the top-level structure (+updated figure)
  • Simplified all tables in the document and gave them the = same look and feel.
  • Updated compression and packing algorithms (and added= references).   

 

There are still TBDs in the document and I noticed a= few bugs here and there.

Will fix them asap but wanted to have something for = the group to look at.

 

However, I hope the document is easier to read. Plea= se have a look at:

https://www.ietf.org/id/draft-ietf-suit-manifest-05.txt=

 

Ciao

Hannes

This draft is a work item of the Software Updates for Internet of Things WG of the IETF. Title : A Firmware Update Architecture for Internet of Things Authors : Brendan Moran Hannes Tschofenig David Brown Milosch Meriac Filename : draft-ietf-suit-architecture-10.txt Pages : 30 Date : 2020-05-27 Abstract: Vulnerabilities with Internet of Things (IoT) devices have raised the need for a solid and secure firmware update mechanism that is also suitable for constrained devices. Incorporating such update mechanism to fix vulnerabilities, to update configuration settings as well as adding new functionality is recommended by security experts. This document lists requirements and describes an architecture for a firmware update mechanism suitable for IoT devices. The architecture is agnostic to the transport of the firmware images and associated meta-data.

This draft is a work item of the Software Updates for Internet of Things WG of the IETF. Title : A Firmware Update Architecture for Internet of Things Authors : Brendan Moran Hannes Tschofenig David Brown Milosch Meriac Filename : draft-ietf-suit-architecture-11.txt Pages : 28 Date : 2020-05-27 Abstract: Vulnerabilities with Internet of Things (IoT) devices have raised the need for a solid and secure firmware update mechanism that is also suitable for constrained devices. Incorporating such update mechanism to fix vulnerabilities, to update configuration settings as well as adding new functionality is recommended by security experts. This document lists requirements and describes an architecture for a firmware update mechanism suitable for IoT devices. The architecture is agnostic to the transport of the firmware images and associated meta-data.
