Recent news (see <a href=\"http:\/\/blog.cryptographyengineering.com\/2015\/12\/on-juniper-backdoor.html\">Matthew Green<\/a> for an explanation) is that this bad crypto actually was used in something quite important: widely used firewall\/VPN hardware from Juniper Networks.  Quite likely this was used by the NSA to get access to much of the traffic on a wide variety of networks.\n<p>The story is actually much more complicated than one can believe, with a still unclear sequence of changes in the software indicating that others, possibly a foreign government, took advantage of the NSA backdoor to compromise these systems. Green points out that this makes very clear the problem with government-mandated backdoors: even if you trust the government, they make it much easier for others to take advantage of the security problems they have introduced:<\/p>\n<blockquote><p>One of the most serious concerns we raise during these meetings is the possibility that encryption backdoors could be subverted. Specifically, that a backdoor intended for law enforcement could somehow become a backdoor for people who we don&#8217;t trust to read our messages. Normally when we talk about this, we&#8217;re concerned about failures in storage of things like escrow keys. What this Juniper vulnerability illustrates is that the danger is much broader and more serious than that.<\/p>\n<p>The problem with cryptographic backdoors isn&#8217;t that they&#8217;re the only way that an attacker can break into our cryptographic systems. It&#8217;s merely that they&#8217;re one of the best. They take care of the hard work, the laying of plumbing and electrical wiring, so attackers can simply walk in and change the drapes.<\/p><\/blockquote>\n<\/li>\n<li>If you just can&#8217;t get enough of my and other people&#8217;s views on string theory, Ben Winterhalter has <a href=\"http:\/\/daily.jstor.org\/i-heart-physics-love-story\/\">a piece on the Jstor blog<\/a>, telling the story of his attempts to figure out what&#8217;s going on with extra dimensions.<\/li>\n<li>Among the many great articles at Quanta, I can recommend <a href=\"https:\/\/www.quantamagazine.org\/20151208-four-mathematicians\/\">this one<\/a>, which features my Columbia colleague Wei Zhang.\n<\/li>\n<\/ul>\n<p>Happy New Year!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A collection of links to round out the year: The Seminaire Bourbaki talks this January look unusually interesting.
