From 5a8dfe33a47d2e72e977c46cb24040e714e1eeab Mon Sep 17 00:00:00 2001 From: "A.J. Stein" Date: Wed, 22 Nov 2023 14:12:59 -0500 Subject: [PATCH 001/106] Fix Anaconda environment configuration for tests In order to fix scitt-community/scitt-api-emulator#38, we need to hard pin the version of Werkzeug used by Flask to avoid the changes after to how functions are organized in the library's modules. See PR Sanster/lama-cleaner#390 with a related solution (not specific to Anaconda approach, but informative). See [StackOverflow](https://stackoverflow.com/a/77217971) post for details. --- environment.yml | 1 + 1 file changed, 1 insertion(+) diff --git a/environment.yml b/environment.yml index 90e61fa8..b62f9e81 100644 --- a/environment.yml +++ b/environment.yml @@ -38,3 +38,4 @@ dependencies: - jsonschema==4.17.3 - jwcrypto==1.5.0 - PyJWT==2.8.0 + - werkzeug==2.2.2 From a7f0c7be0c8f6b73eb249b943f653d21ad2f6032 Mon Sep 17 00:00:00 2001 From: John Andersen Date: Fri, 10 Nov 2023 21:00:20 +0100 Subject: [PATCH 002/106] create statement: As standalone file for rev a4645e4bc3e78ad5cfd9f8347c7e0ac8267c1079 of SCITT arch Related: https://github.com/ietf-wg-scitt/draft-ietf-scitt-architecture/commit/a4645e4bc3e78ad5cfd9f8347c7e0ac8267c1079 Signed-off-by: John Andersen --- environment.yml | 1 + scitt_emulator/create_statement.py | 192 +++++++++++++++++++++++++++++ setup.py | 2 + 3 files changed, 195 insertions(+) create mode 100644 scitt_emulator/create_statement.py diff --git a/environment.yml b/environment.yml index b62f9e81..f83f20ba 100644 --- a/environment.yml +++ b/environment.yml @@ -39,3 +39,4 @@ dependencies: - jwcrypto==1.5.0 - PyJWT==2.8.0 - werkzeug==2.2.2 + - cwt==2.7.1 diff --git a/scitt_emulator/create_statement.py b/scitt_emulator/create_statement.py new file mode 100644 index 00000000..84ec9215 --- /dev/null +++ b/scitt_emulator/create_statement.py @@ -0,0 +1,192 @@ +# Copyright (c) SCITT Authors +# Licensed under the MIT License. +import pathlib +import argparse +from typing import Optional + +import cwt +import pycose +import pycose.headers +import pycose.messages +import pycose.keys.ec2 + +# TODO jwcrypto is LGPLv3, is there another option with a permissive licence? +import jwcrypto.jwk + + +@pycose.headers.CoseHeaderAttribute.register_attribute() +class CWTClaims(pycose.headers.CoseHeaderAttribute): + identifier = 14 + fullname = "CWT_CLAIMS" + + +@pycose.headers.CoseHeaderAttribute.register_attribute() +class RegInfo(pycose.headers.CoseHeaderAttribute): + identifier = 393 + fullname = "REG_INFO" + + +@pycose.headers.CoseHeaderAttribute.register_attribute() +class Receipt(pycose.headers.CoseHeaderAttribute): + identifier = 394 + fullname = "RECEIPT" + + +@pycose.headers.CoseHeaderAttribute.register_attribute() +class TBD(pycose.headers.CoseHeaderAttribute): + identifier = 395 + fullname = "TBD" + + +def create_claim( + claim_path: pathlib.Path, + issuer: str, + subject: str, + content_type: str, + payload: str, + private_key_pem_path: Optional[str] = None, +): + # https://ietf-wg-scitt.github.io/draft-ietf-scitt-architecture/draft-ietf-scitt-architecture.html#name-signed-statement-envelope + + # Registration Policy (label: TBD, temporary: 393): A map containing + # key/value pairs set by the Issuer which are sealed on Registration and + # non-opaque to the Transparency Service.

refer to the [Registration Policies](registration_policies.md) doc for +> more information about claim insert policies. + +In this example Alice and Bob each have their own instance of SCITT. Alice's +insert policy differs from Bob's slightly. Alice and Bob's instances federate +with each other. This means when claims are inserted into one instance and are +given and entry ID and a receipt at notification is sent to the other instance. +The other instance decides if it wants to create a corresponding entry ID and +receipt local to it. + +Federation can be helpful when some aspects of insert policy validation are +shared. By federating with entities an instance trusts for those aspects of +insert policy and instance and it's owner(s) may be able to reduce investment in +compute or other activities required for claim validation. + +As a more specific example, entities may share a common set of insert policy +criteria defined in a collaborative manner (such as a working group). +Attestations of alignment to the [S2C2F](https://github.com/ossf/s2c2f/blob/main/specification/framework.md#appendix-relation-to-scitt) +are one such example. In addition to the requirements / evaluation criteria +defined by the OpenSSF's Supply Chain Integrity Working Group an entity may +desire to evaluate attestations of alignment with added requirements
