Submission + - Announcing the first SHA1 collision (googleblog.com)

matafagafo writes: Google Security Blog just published

Cryptographic hash functions like SHA-1 are a cryptographer’s swiss army knife. You’ll find that hashes play a role in browser security, managing code repositories, or even just detecting duplicate files in storage. Hash functions compress large amounts of data into a small message digest. As a cryptographic requirement for wide-spread use, finding two messages that lead to the same digest should be computationally infeasible. Over time however, this requirement can fail due to attacks on the mathematical underpinnings of hash functions or to increases in computational power. Today, 10 years after of SHA-1 was first introduced, we are announcing the first practical technique for generating a collision.


Comment Re:Uh, then why was the analog TV spectrum sold of (Score 1) 64

The analog TV bands are not very suitable for high capacity demands. Most of those bands are already being claimed for other purposes as well. And digital TV still chews up quite a bit of those bands.

Lower frequencies also means bulkier antennas on the mobile devices - or less efficient antennas. So there's no real point in trying to reach for those bands.

Also see this allocation chart, even though it's a bit dated it's still interesting. It seems to have a segment between 11.7 and 12.2 GHz that is planned for Mobile use.

Submission + - Google: 99.95% of Recent 'Trusted' DMCA Notices Were Bogus (torrentfreak.com)

AmiMoJo writes: In comments submitted to a U.S. Copyright Office consultation, Google has given the DMCA a vote of support, despite widespread abuse. Noting that the law allows for innovation and agreements with content creators, Google says that 99.95% of URLs it was asked to take down last month didn't even exist in its search indexes. “For example, in January 2017, the most prolific submitter submitted notices that Google honored for 16,457,433 URLs. But on further inspection, 16,450,129 (99.97%) of those URLs were not in our search index in the first place.”

Skip bringing your smartphone and get a "dumb" phone where you can hardly produce a text message.

I doubt that they would capture any serious offender this way - they have other means to get their stuff through. A micro SD is so small that it's easy to conceal.

But otherwise I have realized that there's no real point in visiting the US these days considering the banana republic government that's in place. Nothing wrong with the people, just the election system that makes sure that only the worst alternatives are available. The only candidate last election that at least had some ambition outside the realm of power or control was Sanders.
