Frederick, all, my former supervisor, Dr. Nils Gruschka, wrote his Ph.D. thesis about streaming-based processing of XML Security (including streaming-based XML Signature 1.0 and XML Encryption 1.0). I'll contact him regarding performance data, I'm pretty sure he has some measurement graphics available. Unfortunately, the thesis is written in german, so I'll have to translate the data before sending around. Further, one of my former students did a similar implementation for streaming-based XML Signature 1.0, hence his thesis contains some data that might be useful as well. Please note that both sources are for streaming-based implementations of XML Security 1.0, and their performance data will differ from what we have done with XML Signature 2.0. However, I think the advantage of streaming in comparison to DOM should become clear from their performance graphs as well. best regards Meiko Am 26.10.2010 19:59, schrieb Frederick.Hirsch@nokia.com: > Here are the various items we have so far related to XML Security 2.0 performance (focus on canonicalization and signature): > > thesis re C14N 2.0 parameters > http://lists.w3.org/Archives/Public/public-xmlsec/2010Oct/0038.html (Meiko) > > Raul Benito Garcia thesis (in Spanish that I do not read) > http://lists.w3.org/Archives/Public/public-xmlsec/2009Nov/0046.html (thesis via Sean) > > argument for constraining > http://www.w3.org/2008/xmlsec/Drafts/performance/c14n-subtree/constrained-cases-description.pdf (constrained cases, Pratik) > http://lists.w3.org/Archives/Public/public-xmlsec/2009Apr/0045.html > > Canonicalization measurements > http://lists.w3.org/Archives/Public/public-xmlsec/2009May/0003.html (Pratik) > > probably not relevant to our analysis of 2.0 improvements, Alternative algorithms (MQQ) > http://lists.w3.org/Archives/Public/public-xmlsec/2009Nov/0047.html (Chris) > > Is anyone aware of any other performance material that is relevant to showing how XML Security 2.0 addresses the performance issues in 1.1? > > regards, Frederick > > Frederick Hirsch > Nokia > > > > -- Dipl.-Inf.
