Submission + - Richard Lipton on new attacks on public key crypto

tbonefrog writes: Major experts such as Richard Lipton are raising red flags over recent breakthroughs endangering all known systems of public key crypto. In February Antoine Joux produced a new record subexponential discrete logarithm algorithm running at L(1/4) speed and beating the long-standing L(1/3) mark. On June 20 a quasipolynomial algorithm was announced at the Workshop on Number-Theoretic Algorithms for Asymmetric Cryptology in France, and explained by Stephen Galbraith, and these other blogs. Lipton has not yet commented on the latest breakthrough.

Discrete logarithm and factoring are different problems but progress on one tends to lead to progress in the other.

Submission + - Intel to replace passwords with handwaving (huffingtonpost.com)

tbonefrog writes: "Intel is building a biometric palm scanner into laptops and tablets. Just off the top of my head, use of this technology to 'replace passwords' has a few flaws: no information on how to register a user, what if I injure my hand, what if my palm data gets stolen, who is going to correlate palms with fingerprints, if they want my laptop do they have to also cut off my hand..."

Submission + - NASA peddling science fiction to minors (prnewswire.com)

tbonefrog writes: NASA plans to hire propagandists (sci-fi novelists) to subject impressionable young minds to story lines calculated to inflate the Agency's budget over time. I'm willing to bet there won't be a lot of stories about how cool it is do to science with robots as opposed to human exploration. Maybe we'll even throw in some space aliens, and 70 virgins to all the heroes who get snookered into flying on a death trap to die on Mars.
