Exclamation The U.S. are fighting with encryption, again...

The article:
Code:
 https://cyberlaw.stanford.edu/blog/2020/06/there%E2%80%99s-now-even-worse-anti-encryption-bill-earn-it-doesn%E2%80%99t-make-earn-it-bill-ok
Honestly it's difficult for me to believe how much some U.S. politicians hate encryption, specifically with this kind of magnitude! To me it looks like they are heading towards a 1984 scenario with these kind of attitudes, yikes!
It probably won't pass, but as the article says it might be made this insane to make the EARN IT act look "more reasonable", yeah right...
I'm glad OpenBSD is based in Canada, and sure hope none of this garbage gets over to Europe directly. Even if some terrible ideas were already introduced, like contact tracing.

I find it weird how in that Snowden movie they claimed that computers, phones, and commercial operating systems have NSA back doors in them, yet in the USA politicians are getting hysterical about encryption. If the computers and phones have NSA back doors, why do the politicians care if the communications between them are encrypted? Why not ask the NSA for the access codes?

It isn't necessarily "backdoors," per se, though Mr. Stone may have used that term in his screenplay for dramatic impact. It appears to be manipulation of cryptographic constants in published standards, to provide decryption advantages.

I was looking into Curve25519 today, and learned that there was conjecture of a possible backdoor in a NIST-standard psuedo random number generator, noted below. Beyond that -- and more importantly -- were all the constants that were used in Elliptic Curve Cryptography standards of the day which were called into question.

Since then, Curve25519 has become the de facto alternative to P-256, and is used in a wide variety of applications....

What about those management engines they have been putting on the CPUs, where they have a chip with its own operating system watching all the goings on, on the CPU? Is that not a backdoor?



I wish there was a website you could go to to learn all these techniques they are using to break encryption, as I have some files from 6 years ago that I lost the password to.

Some years ago, I took an introduction to cryptography class that Stanford offered online. It began well enough, but my insufficient background in mathematics theory made the course impossible to continue by the 8th or 9th week in.

1. Perhaps they can't break without much resources and undetected everywhere.
2. This kind of technology subversion may be found unlawful or more regulated/supervised by court in the future. It is better for them to pass a law to make it lawful.
Some actions may be now lawful for national security, but not lawful for regular criminal investigations.
