Dual EC — a standardized back door
What happens if a governmental agency takes influence on a technical
standardization process in order to inject a back door into
cryptographic primitives? Due to the revelations by Edward Snowden, we
do know that this is not a theoretical question: most likely the NSA
has infected the NIST Special Publication 800-90 with a backdoored
specification of the Dual EC pseudo random number generator. This talk
attempts to shed some light into the standardization process of Dual
EC, explains the basic back door in Dual EC, and gives
specific performance numbers for several attacks on TLS
implementations using Dual EC.
