双椭圆曲线确定性随机比特生成器（dual elliptic curve deterministic random bit generator，缩写Dual_EC_DRBG）被广泛认为被NSA植入了后门，它获得了美国国家标准技术研究院的认可，并成为安全公司RSA加密产品默认使用的伪随机数生成器。比利时计算机科学专家Aris Adamantiadis发表了Dual_EC_DRBG后门的概念验证研究报告，认为Dual_EC_DRBG的后门是被有意植入的，指出Dual_EC_DRBG使用了一个秘密的值去计算一个椭圆曲线点常量，他并不知道这个秘密值，认为可能只有NSA能利用这个后门。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
