  32         <p><em>This is a copy of
  33 <a href="https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html">an
  34 email I posted to the nikita-noark mailing list</a>.  Please follow up
  35 there if you would like to discuss this topic.  The background is that
  36 we are making a free software archive system based on the Norwegian
  37 <a href="https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden">Noark
  38 5 standard</a> for government archives.</em></p>
  39
  40 <p>I've been wondering a bit lately how trusted timestamps could be
  41 stored in Noark 5.
  42 <a href="https://en.wikipedia.org/wiki/Trusted_timestamping">Trusted
  43 timestamps</a> can be used to verify that some information
  44 (document/file/checksum/metadata) have not been changed since a
  45 specific time in the past.  This is useful to verify the integrity of
  46 the documents in the archive.</p>
  47
  48 <p>Then it occured to me, perhaps the trusted timestamps could be
  49 stored as dokument variants (ie dokumentobjekt referered to from
  50 dokumentbeskrivelse) with the filename set to the hash it is
  51 stamping?</p>
  52
  53 <p>Given a "dokumentbeskrivelse" with an associated "dokumentobjekt",
  54 a new dokumentobjekt is associated with "dokumentbeskrivelse" with the
  55 same attributes as the stamped dokumentobjekt except these
  56 attributes:</p>
  57
  58 <ul>
  59
  60 <li>format -> "RFC3161"
  61 <li>mimeType -> "application/timestamp-reply"
  62 <li>formatDetaljer -> "&lt;source URL for timestamp service&gt;"
  63 <li>filenavn -> "&lt;sjekksum&gt;.tsr"
  64
  65 </ul>
  66
  67 <p>This assume a service following
  68 <a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> is
  69 used, which specifiy the given MIME type for replies and the .tsr file
  70 ending for the content of such trusted timestamp.  As far as I can
  71 tell from the Noark 5 specifications, it is OK to have several
  72 variants/renderings of a dokument attached to a given
  73 dokumentbeskrivelse objekt.  It might be stretching it a bit to make
  74 some of these variants represent crypto-signatures useful for
  75 verifying the document integrity instead of representing the dokument
  76 itself.</p>
  77
  78 <p>Using the source of the service in formatDetaljer allow several
  79 timestamping services to be used.  This is useful to spread the risk
  80 of key compromise over several organisations.  It would only be a
  81 problem to trust the timestamps if all of the organisations are
  82 compromised.</p>
  83
  84 <p>The following oneliner on Linux can be used to generate the tsr
  85 file.  $input is the path to the file to checksum, and $sha256 is the
  86 SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned
  87 above).</p>
  88
  89 <p><blockquote><pre>
  90 openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
  91   | curl -s -H "Content-Type: application/timestamp-query" \
  92       --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr
  93 </pre></blockquote></p>
  94
  95 <p>To verify the timestamp, you first need to download the public key
  96 of the trusted timestamp service, for example using this command:</p>
  97
  98 <p><blockquote><pre>
  99 wget -O ca-cert.txt \
 100   https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
 101 </pre></blockquote></p>
 102
 103 <p>Note, the public key should be stored alongside the timestamps in
 104 the archive to make sure it is also available 100 years from now.  It
 105 is probably a good idea to standardise how and were to store such
 106 public keys, to make it easier to find for those trying to verify
 107 documents 100 or 1000 years from now. :)</p>
 108
 109 <p>The verification itself is a simple openssl command:</p>
 110
 111 <p><blockquote><pre>
 112 openssl ts -verify -data $inputfile -in $sha256.tsr \
 113   -CAfile ca-cert.txt -text
 114 </pre></blockquote></p>
 115
 116 <p>Is there any reason this approach would not work?  Is it somehow against
 117 the Noark 5 specification?</p>

 139 melder i dag</a> om feil i eksamensoppgavene for eksamen i politikk og
 140 menneskerettigheter, der teksten i bokmåls og nynorskutgaven ikke var
 141 like.  Oppgaveteksten er gjengitt i artikkelen, og jeg ble nysgjerring
 142 på om den fri oversetterløsningen
 143 <a href="https://www.apertium.org/">Apertium</a> ville gjort en bedre
 144 jobb enn Utdanningsdirektoratet.  Det kan se slik ut.</p>
 145
 146 <p>Her er bokmålsoppgaven fra eksamenen:</p>
 147
 148 <blockquote>
 149 <p>Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers
 150 rolle og muligheter til å håndtere internasjonale utfordringer, som
 151 for eksempel flykningekrisen.</p>
 152
 153 <p>Vedlegge er eksempler på tekster som kan gi relevante perspektiver
 154 på temaet:</p>
 155 <ol>
 156 <li>Flykningeregnskapet 2016, UNHCR og IDMC
 157 <li>«Grenseløst Europa for fall» A-Magasinet, 26. november 2015
 158 </ol>
 159
 160 </blockquote>
 161
 162 <p>Dette oversetter Apertium slik:</p>
 163
 164 <blockquote>
 165 <p>Drøft utfordringane knytte til nasjonalstatane sine og rolla til
 166 andre aktørar og høve til å handtera internasjonale utfordringar, som
 167 til dømes *flykningekrisen.</p>
 168
 169 <p>Vedleggja er døme på tekster som kan gje relevante perspektiv på
 170 temaet:</p>
 171
 172 <ol>
 173 <li>*Flykningeregnskapet 2016, *UNHCR og *IDMC</li>
 174 <li>«*Grenseløst Europa for fall» A-Magasinet, 26. november 2015</li>
 175 </ol>
 176
 177 </blockquote>
 178
 179 <p>Ord som ikke ble forstått er markert med stjerne (*), og trenger
 180 ekstra språksjekk.  Men ingen ord er forsvunnet, slik det var i
 181 oppgaven elevene fikk presentert på eksamen.  Jeg mistenker dog at
 182 "andre aktørers rolle og muligheter til ..." burde vært oversatt til
 183 "rolla til andre aktørar og deira høve til ..." eller noe slikt, men
 184 det er kanskje flisespikking.  Det understreker vel bare at det alltid
 185 trengs korrekturlesning etter automatisk oversettelse.</p>
