Electronic Signatures and Infrastructures (ESI); CAdES digital signatures - Testing Conformance and Interoperability; Part 4: Testing conformance of CAdES baseline signatures (V1.1.1)
The present document defines the set of checks to be performed for testing conformance of CAdES signatures against CAdES baseline signatures as specified in ETSI EN 319 122-1 [1]. The present document does not specify checks leading to conclude whether a signature is technically valid or not (for instance@ it does not specify checks for determining whether the cryptographic material present in the signature may be considered valid or not). In consequence@ no conclusion may be inferred regarding the technical validity of a signature that has been successfully tested by any tool conformant to the present document. Checks specified by the present document are exclusively constrained to elements specified by CAdES [1]. Regarding CAdES attributes@ the present document explicitly differentiates between structural requirements that are defined on building blocks@ and the requirements specified for CAdES baseline signatures conformance. The present document is intentionally not linked to any software development technology and is also intentionally agnostic on implementation strategies. This is one of the reasons why the test assertions set specified in the present document includes tests on the correctness of the structure of all the elements specified by CAdES [1].
