Subway Elevators and Movie-Plot Threats

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/01/subway_elevator.html

Local residents are opposing adding an elevator to a subway station because terrorists might use it to detonate a bomb. No, really. There’s no actual threat analysis, only fear:

“The idea that people can then ride in on the subway with a bomb or whatever and come straight up in an elevator is awful to me,” said Claudia Ward, who lives in 15 Broad Street and was among a group of neighbors who denounced the plan at a recent meeting of the local community board. “It’s too easy for someone to slip through. And I just don’t want my family and my neighbors to be the collateral on that.”


Local residents plan to continue to fight, said Ms. Gerstman, noting that her building’s board decided against putting decorative planters at the building’s entrance over fears that shards could injure people in the event of a blast.

“Knowing that, and then seeing the proposal for giant glass structures in front of my building ­- ding ding ding! — what does a giant glass structure become in the event of an explosion?” she said.

In 2005, I coined the term “movie-plot threat” to denote a threat scenario that caused undue fear solely because of its specificity. Longtime readers of this blog will remember my annual Movie-Plot Threat Contests. I ended the contest in 2015 because I thought the meme had played itself out. Clearly there’s more work to be done.

NSA Best Scientific Cybersecurity Paper Competition

Every year, the NSA has a competition for the best cybersecurity paper. Winners get to go to the NSA to pick up the award. (Warning: you will almost certainly be fingerprinted while you’re there.)

NIST Starts Planning for Post-Quantum Cryptography

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2016/05/nist_starts_pla.html

Last year, the NSA announced its plans for transitioning to cryptography that is resistant to a quantum computer. Now, it’s NIST’s turn. Its just-released report talks about the importance of algorithm agility and quantum resistance. Sometime soon, it’s going to have a competition for quantum-resistant public-key algorithms:

Creating those newer, safer algorithms is the longer-term goal, Moody says. A key part of this effort will be an open collaboration with the public, which will be invited to devise and vet cryptographic methods that — to the best of experts’ knowledge — ­will be resistant to quantum attack. NIST plans to launch this collaboration formally sometime in the next few months, but in general, Moody says it will resemble past competitions such as the one for developing the SHA-3 hash algorithm, used in part for authenticating digital messages.

“It will be a long process involving public vetting of quantum-resistant algorithms,” Moody said. “And we’re not expecting to have just one winner. There are several systems in use that could be broken by a quantum computer­ — public-key encryption and digital signatures, to take two examples­ — and we will need different solutions for each of those systems.”

The report rightly states that we’re okay in the symmetric cryptography world; the key lengths are long enough.

This is an excellent development. NIST has done an excellent job with their previous cryptographic standards, giving us a couple of good, strong, well-reviewed, and patent-free algorithms. I have no doubt this process will be equally excellent. (If NIST is keeping a list, aside from post-quantum public-key algorithms, I would like to see competitions for a larger-block-size block cipher and a super-fast stream cipher as well.)
