As we announced in the PAdES post, ETSI Centre for Testing and Interoperability (CTI) is organizing a new Remote Plugtests Interop events for XAdES Signatures from 14th March to 28th March 2012.
This testing will provide full test coverage of the both specifications including testing signatures evolution, simulating real life situations.
This Plugtests event will enable participants to conduct 4 types of tests (Interoperability and Conformance):
- Generation and cross-verification (Positive) tests
- Only-verification (Negative) tests
- Signature Upgrade tests
- Conformance testing on XAdES Baseline Profile signatures
The purpose of these events is:
- To enable participants to assess the level of interoperability of XAdES.
- To identify additional issues that should be taken into account in future XAdES standardisation activities.
- To improve the quality of XAdES specifications.
- To ease the introduction of XAdES signatures, by providing the means to solve interoperability problems before widespread deployment..
You can get more information on plugtests portal for electronic signatures: http://xades-portal.etsi.org/pub/index.shtml
As shown in our website, we can provide you a little description about de XAdES profiles differing in protection level offered. Each profile includes and extends the previous one:
- XAdES, basic form just satisfying Directive legal requirements for advanced signature;
- XAdES-T (timestamp), adding timestamp field to protect against repudiation;
- XAdES-C (complete), adding references to verification data (certificates and revocation lists) to the signed documents to allow off-line verification and verification in future (but does not store the actual data);
- XAdES-X (extended), adding timestamps on the references introduced by XAdES-C to protect against possible compromise of certificates in chain in future;
- XAdES-X-L (extended long-term), adding actual certificates and revocation lists to the signed document to allow verification in future even if their original source is not available;
- XAdES-A (archival), adding possibility for periodical timestamping (e.g. each year) of the archived document to prevent compromise caused by weakening signature during long-time storage period.
