# Digital signature algorithms within the European Union

I've just noticed that US NIST has accepted DSA as a digital signature standard. Does the European Union have a similar standard, specifying an algorithm to use when digitally signing messages?

I have been looking this up for some time now, but I fail to find a reasonable answer.

• I don't know for sure if there's anything else, but europe actually accepted DSA as signature algorithm - no need to invent their own. The only exception may be (EC)GDSA which is just a minor modification. For ECGDSA refer to TR-03111 – SEJPM Aug 23 '15 at 15:35
• @SEJPM - thanks for your comment, it has helped in searching by using alternative wording. I found that enisa.europa.eu has a wealth of information on the subject. In short: there are a lot of recommendations, but each member state applies its own algorithms for the moment. The PDF on this page is from 2011, but sums it up enough, for me enisa.europa.eu/activities/identity-and-trust/library/… – twan163 Aug 23 '15 at 16:59

Except if you are picky with updates of references, there is such standard. DSA, RSA, ECDSA-$F_p$, ECDSA-$F_{2^n}$, are approved by ETSI TS 102 176-1 V2.1.1 (2011-07) (Electronic Signatures and Infrastructures (ESI); Algorithms and Parameters for Secure Electronic Signatures; Part 1: Hash functions and asymmetric algorithms), which essentially is an update of ETSI SR 002 176 V1.1.1 (2003-03) (Algorithms and Parameters for Secure Electronic Signatures), which is referenced by CWA 14169:2004 (Secure signature-creation devices “EAL 4+”), which (in an earlier edition that it supersedes) is referenced by Commission decision 2003/511/EC (on the publication of reference numbers of generally recognised standards for electronic signature products in accordance with Directive 1999/93/EC of the European Parliament and of the Council).
