Backdoor in TETRA Police Radios

Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world.

Most interestingly is the researchers’ findings of what they describe as the backdoor in TEA1. Ordinarily, radios using TEA1 used a key of 80-bits. But Wetzels said the team found a “secret reduction step” which dramatically lowers the amount of entropy the initial key offered. An attacker who followed this step would then be able to decrypt intercepted traffic with consumer-level hardware and a cheap software defined radio dongle.

Schneier with the obvious take:

Why aren’t we done with secret, proprietary cryptography? It’s just not a good idea.

GPT-4 and ChatGPT study shows LLMs are getting dumber

I'm inclined to agree in general. GPT has actually gotten worse over time.

For one it's just way too locked down now. But I also have noticed a decline in overall quality of responses, especially for technical stuff. It used to translate between programming languages quite well, and that's been more broken lately.

I'm wondering if they purged a bunch of copyrighted material from it and that's why it got dumber.

EU gives its blessing to reopen data pipelines to the US

The EU-US Data Privacy Framework (DPF) is the third attempt between the trading bloc and the US to iron out privacy kinks in the flow of data about their citizens. This latest agreement marks the EU's determination that "the United States ensures an adequate level of protection – comparable to that of the European Union – for personal data transferred from the EU to US companies under the new framework," the Commission said in a statement.

Key to today's decision [PDF] was an October executive order signed by US President Joe Biden that the Commission said adds new safeguards that address the problems raised with the second attempt at a transatlantic data agreement, Privacy Shield.
