The paper, published this week, expands on previous research by German academics in 2012 by rapidly speeding up the attack and showing that the encryption used in popular Inmarsat satellite phones can be cracked in "real time."Using their proposed inversion attack thousands of time on a 3.3GHz satellite stream, the researchers were able to reduce the search space for the 64-bit encryption key, effectively making the decryption key easier to find.
The end result was that encrypted data could be cracked in a fraction of a second. more
