These constants are listed in Appendix A of the NIST publication, but nowhere is it explained where they came from.<\/p>\n<p>What Shumow and Ferguson showed is that these numbers have a relationship with a second, secret set of numbers that can act as a kind of skeleton key. If you know the secret numbers, you can predict the output of the random-number generator after collecting just 32 bytes of its output. To put that in real terms, you only need to monitor one TLS internet encryption connection in order to crack the security of that protocol. If you know the secret numbers, you can completely break any instantiation of Dual_EC_DRBG. <\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Ich lach mich tot: http:\/\/www.heise.de\/newsticker\/meldung\/OpenSSL-mit-kaputter-Hintertuer-2072370.html Die Open-Source-Bibliothek f\u00fcr Krypto-Funktionen OpenSSL enth\u00e4lt auch eine Implementierung des Pseudo-Zufallszahlen-Generators \"Dual EC DRBG\" \u2013 das ist der mit der NSA-Backdoor.
