[cryptography] Dual_EC_DRBG was cooked, but not AES?

2013-09-22 Thread Ed Stone
The Snowden revelations describe several methods by which NSA committed kleptography, caused compliance by hardware makers and influenced standards. Why has AES escaped general suspicion? Are we to believe that NIST tested, selected, endorsed and promulgated an algorithm that was immune to

2013/9/22 Tony Arcieri basc...@gmail.com Furthermore, 3DES continues to remain a viable cipher. I, personally, find that a most commendable and remarkable fact. To use DES with longer keying (and more rounds) is, to this very day, a solid choice. It makes one wonder why the longer keys weren't
