GSM – SRSLY?

Karsten Nohl, Chris Paget – 26C3, Berlin

Summary:

GSM Encryption needs to be shown insecure

GSM is constantly under attack:

A5/1 cipher shown insecure

repeatedly

Lack of network authentication allow

MITM intercept (IMSI Catcher)

However, GSM is used in a growing

number of sensitive applications:

Voice calls, obviously

SMS for banking

Seeding RFID/NFC secure elements

for access control, payment and

authentication

 To rectify the perception of

GSM‟s security, we demon-

strate its weakness

 The community has

computed the cryptographic

base for a public

demonstration of cracking

GSM

 This presentation details

motives, approach and next

steps of the “A5/1 Cracking

Project”

GSM is global, omnipresent and insecure

GSM

encryption

introduced

in 1987 …

… then

disclosed

and

shown

insecure

in 1994

We need to publicly demonstrate that GSM

uses insufficient encryption

'97 '00 '03 '05

A5/1 shown academically broken

A5/1 shown more …

… and more …

… and more broken.

'06

Broken with massive computation

'03/'08

Rainbow table computation

Not enough known data in GSM packets

Too expensive

Tables never released

Karsten Nohl - A5/1 Cracking

Public break attempts

… that didn't work.

GSM encryption is constantly being broken, just not

publicly

 Academic breaks of A5/1

cipher are not practical

[EC1997, FSE2000,

Crypto2003, SAC2005]

 Cracking tables computed

in 2008 but never released

 15 years of of A5/1

research have not

produced a single PoC

 (until today)

Karsten Nohl - A5/1 Cracking

All public break attempts of

A5/1 have failed so far

Meanwhile … … A5/1 is constantly

being circumvented

by intelligence, law

enforcement, and

criminals
