McBits: fast constant-time code-based cryptography
This paper presents extremely fast algorithms for code-based
public-key cryptography, including full protection against timing
attacks. For example, at a 2^128 security level, this paper achieves a
reciprocal decryption throughput of just 60493 cycles (plus cipher cost
etc.) on a single Ivy Bridge core. These algorithms rely on an additive
FFT for fast root computation, a transposed additive FFT for fast
syndrome computation, and a sorting network to avoid cache-timing attacks.
CHES 2013 was late August, already. Was anyone there? Any comments on
(skimming paper reveals one gotcha -- huge keys, 64k for 2^80 security.
I'm guessing that FFT==fast fourier transform.)
