More opinions still welcome:-) Thanks, Stephen. -------- Original Message -------- Subject: [Technical Errata Reported] RFC4086 (3106) Date: Sun, 5 Feb 2012 03:52:37 -0800 (PST) From: RFC Errata System <rfc-editor@rfc-editor.org> To: Donald.Eastlake@motorola.com, jis@mit.edu, steve@stevecrocker.com, iesg@ietf.org CC: fw@deneb.enyo.de, rfc-editor@rfc-editor.org The following errata report has been submitted for RFC4086, "Randomness Requirements for Security". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=4086&eid=3106 -------------------------------------- Type: Technical Reported by: Florian Weimer <fw@deneb.enyo.de> Section: 4.4 Original Text ------------- (see below) Corrected Text -------------- (remove entire section) Notes ----- Compression is not suitable for de-skewing, even if headers are removed. For most compression algorithms, discriminators are known. For instance, in gzip output, the most significant bit of each byte is set with a frequency somewhat above 0.501 (except for small inputs). This means that the output is not uniformly distributed even when looking at isolated bytes. I recommend removal of the entire section. Instructions: ------------- This errata is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC4086 (draft-eastlake-randomness2-10) -------------------------------------- Title : Randomness Requirements for Security Publication Date : June 2005 Author(s) : D. Eastlake 3rd, J. Schiller, S. Crocker Category : BEST CURRENT PRACTICE Source : IETF - NON WORKING GROUP Area : N/A Stream : IETF Verifying Party : IESG
