Cell Phone Crypto Penetrated

Israeli researchers have discovered
design flaws that allow the descrambling
of supposedly private conversations
carried by hundreds of millions of wireless
phones.
Alex Biryukov and Adi Shamir describe in a
paper to be published this week how a PC
with 128 MB RAM and large hard drives
can penetrate the security of a phone
call or data transmission in less than one
second.
The flawed algorithm appears in digital
GSM phones made by companies such as
Motorola, Ericsson, and Siemens, and
used by well over 100 million customers in
Europe and the United States. Recent
estimates say there are over 230 million
users worldwide who account for 65
percent of the digital wireless market.
