Subject [jira] [Commented] (WSS-386) Introduce proprietary Compress-Transformation for Encryption / Decryption
Date Sun, 22 Apr 2012 22:51:34 GMT

    [ https://issues.apache.org/jira/browse/WSS-386?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13259292#comment-13259292

Anli Shundi commented on WSS-386:
---------------------------------

For decompression bombs have a configurable maximum size, some default value which can't be
perfect for everybody and an appropriate error message.

Note that this doesn't solve http://www.w3.org/2008/xmlsec/papers/xmlEncCountermeasuresW3C.pdf

> Compressing encrypted content (as usually done on transport layer) is not very efficient
but plain XML is.
> Numbers:
> soap-doc-encrypted-not-compressed.xml = ~19M
> soap-doc-compressed-on-transport.gz = ~ 15M
> soap-doc-compressed-before-xml-encryption.xml = ~1.1M
> The advantages are:
> - Factor n less data on the wire
> - Faster processing on both side because much less data must be encrypted/decrypted (depends
on encryption/compression algorithm)
> Disadvantages:
> - Proprietary
> - Introduces new attack-vector and will be disabled by default for WSS with the introduction
of secure-processing
