| TD: Pre-signed OCSP Responses Using SHA-1

Pre-signed OCSP Responses Using SHA-1, v1.0

Addresses the requirement for OCSP responders that generate signatures on OCSP responses to only provide pre-produced signed responses using SHA-1.

NOTE:If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.

If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.

Conformance Criteria (1)

C1

After December 31, 2010, OCSP responders that generate signatures on OCSP responses using SHA-1 shall only provide signed responses that are pre-produced (i.e., any signed response that is provided to an OCSP client shall have been signed before the OCSP responder received the request from the client).
