[techdirt] GSM Encryption Cracked… GSMA's First Response? That's Illegal!

[National Geographic] North Magnetic Pole Moving East Due to Core Flux. El Pol Nord magnètic es desplaça cap a Rússia a una velocitat de 64 km per any:

The magnetic north pole had moved little from the time scientists first located it in 1831. Then in 1904, the pole began shifting northeastward at a steady pace of about 9 miles (15 kilometers) a year.

In 1989 it sped up again, and in 2007 scientists confirmed that the pole is now galloping toward Siberia at 34 to 37 miles (55 to 60 kilometers) a year.

[The New York Times] Code That Protects Most Cellphone Calls Is Divulged. A Alemanya el 28 de desembre no és el dia de les inocentades, oi?

A German computer engineer said Monday that he had deciphered and published the secret code used to encrypt most of the world’s digital mobile phone calls, in what he called an attempt to expose weaknesses in the security of global wireless systems.

Mr. Nohl said the algorithm’s code book was available on the Internet through services like BitTorrent.

Actualització: Open-Source Effort to Hack GSM

Each GSM phone has its own secret key, which is known by the network. Every time a call is initiated, a new session key for that particular call is derived from the secret key and used to encrypt the call. Nohl aims to crack the session key.

The engineer has designed an open-source software program that participants in his A5/1 cracking project can install on their PCs and use to share the task of computing the lookup tables that make up the cryptography system. The final codebook with the computed tables will be shared across a peer-to-peer network. Therefore, no one computer contains all the files, making it difficult, if not impossible, to remove the cracking tool entirely from the Internet.
