This one is also noteworthy because the algorithm it attacks was developed specifically with resistance to quantum attacks in mind, unlike the breed of public-key crypto currently in use, which is widely known to be vulnerable to quantum attacks.
- tptacek 12y agoThat may be true of Soliloquy, but I'm not sure it's the case that lattice problems were originally researched as an antidote to QC. Lattice theory has applicability to cryptography in general, so it's natural that people explored its suitability as a crypto primitive. I don't think it's reasonable to draw the conclusion from this paper that "cryptographers set out to foil QC and in this case failed". One derivative scheme in a broad class of lattice crypto designs fell, that's all. Lattice crypto has very strong post-quantum crypto marketing, because of NTRU.
