Hi Martijn, We discussed the Signing Service definitions and this is what is proposed, “An organization that generates the Key Pair and securely manages the Private Key associated with a Code Signing Certificate, on behalf of a Subscriber.” Does this work for you? Thanks, Bruce.

Do we need to update the definition? Or put is an note? Or leave as is? We might be over-churning on this definition. What if a third party operates a Signing Service and issues itself key for Code Signing certificates. Same problem. I do think that a definition is a short-cut and not a requirement. Our intention of the BRs is to provide requirements for a Signing Service. The intention of the short-cut Signing Service definition was just to say that it is an organization which securely generates and manages the key pair on behalf of a Subscriber. An entity or organization can fill more than one role. As such, the original proposed definition might be OK. Bruce.

I think it’s important to make sure the definition of Signing Service accurately encompasses the cases where a Subscriber is relying on the CA to provide key generation and protection, but doesn’t accidentally pull anything inappropriate else into scope. If the definition and scope are not properly defined, it is almost inevitable that some existing or future requirement will have unexpected and damaging consequences. -Tim From: Cscwg-public <cscwg-public-boun...@cabforum.org<mailto:cscwg-public-boun...@cabforum.org>> On Behalf Of Corey Bonnell via Cscwg-public Sent: Tuesday, October 17, 2023 12:34 PM To: Bruce Morton <bruce.mor...@entrust.com<mailto:bruce.mor...@entrust.com>>; Martijn Katerbarg <martijn.katerb...@sectigo.com<mailto:martijn.katerb...@sectigo.com>>; cscwg-public@cabforum.org<mailto:cscwg-public@cabforum.org> Subject: Re: [Cscwg-public] Ballot CSC-21: Signing Service Update Hi Bruce, I agree the current definition of Signing Service would encompass the CA’s own Subscriber keys. However, we are proposing to amend the definition to: “An organization other than the Subscriber or any of its Affiliates, that generates the Key Pair and securely manages the Private Key associated with a Subscriber's Code Signing Certificate”. Under this definition, the CA’s own Signing Service would not qualify as a Signing Service for its own Subscriber key pairs.

My first take is an example where a Signing Service must use FIPS 140-2 Level 3 and the Subscriber must use minimum Level 2. So if the Subscriber key was generated by the Signing Service, then Level 3 would apply. I don’t see a conflict as both requirements are met. I guess I am not understanding why the Signing Service requirements would not apply even if the CA was using the Signing Service for its Subscriber’s keys. Thanks, Bruce.

I think this is fine but want to ensure there’s agreement on this interpretation. Thoughts?

Should we reword this to “An organization other than the Subscriber or any of its Affiliates, that generates the Key Pair and securely manages the Private Key associated with a Subscriber's Code Signing Certificate”?

Purpose of the Ballot This ballot updates the “Baseline Requirements for the Issuance and Management of Publicly�\Trusted Code Signing Certificates“ version 3.4 in order to clarify language regarding Signing Service and signing requests. The main goals of this ballot are to: 1. Clarify the Signing Service definition and the expected deployment model. 2. Remove requirements for signing request. 3. Change text so Signing Service is not categorized as a Delegated Third Party. 4. Not allow Signing Service to transport Private Key to Subscriber. 5. Ensure Network Security Requirements are applicable to Signing Service. 6. State audit requirements for Signing Service. The following motion has been proposed by Bruce Morton of Entrust and endorsed by Tim Hollebeek of DigiCert and Ian McMillan. MOTION BEGINS This ballot updates the “Baseline Requirements for the Issuance and Management of Publicly�\Trusted Code Signing Certificates” ("Code Signing Baseline Requirements") based on version 3.4. MODIFY the Code Signing Baseline Requirements as specified in the following redline: https://github.com/cabforum/code-signing/compare/93ee9976cdc4e1104952146e3556800459694874..701d195fa95fe49e8a02435fc40fb0a018686866<https://url.avanan.click/v2/___https:/urldefense.com/v3/__https:/github.com/cabforum/code-signing/compare/93ee9976cdc4e1104952146e3556800459694874..701d195fa95fe49e8a02435fc40fb0a018686866__;!!FJ-Y8qCqXTj2!ai_SiHTiSodTE_VWwZi8Z8QT_M2lCkP6nJYlFupqIB2vMo07Rcbx2E0bKw4GyZ1-pOj0h-PvD9Z5okpQ_IY$___.YXAzOmRpZ2ljZXJ0OmE6bzpiZjFlN2QwMWExMzg3MTlkZjRjMGM1ZTcyOGQwMzk5Nzo2Ojk3ZGE6MjI3ZTJmZTM1NjM2OTBlOGU0ZDIyMzAwZDYyNTc0YjY4NzM0OTEzM2FiZWU0ZDhhMTNhMDMxNmI4ZDBlMDA2MjpoOkY> MOTION ENDS The procedure for this ballot is as follows: Discussion (7 days) ・ Start Time: 2023-10-12 20:00 UTC ・ End Time: Not before 2023-10-19 20:00 UTC Vote for approval (7 days) ・ Start Time: TBD ・ End Time: TBD Any email and files/attachments transmitted with it are intended solely for the use of the individual or entity to whom they are addressed.
