GSM encryption flaws likely to result in significant risks

GSMK Cryptophone : 07 January, 2010  (Technical Article)
Cracking voice encryption on mobile phone communications is becoming increasingly easy as criminals focus on alternative ways of extracting private information
Attacks on the confidentiality of mobile phone calls will be a major security risk to businesses and individuals this year, GSMK Cryptophone has warned. The news comes as researchers announce they have cracked the encryption algorithm which protects most mobile phone communications, putting millions of users at risk from criminals or anyone who wants to exploit private information exchanged during a call.

"Fraudsters are becoming increasingly sophisticated in exploiting the weaknesses of GSM's twenty-year old standard encryption technology, and this threat needs to be taken seriously as many phone users could have an unauthorised third party listening in whether they are a CEO or a celebrity," said Dr Bjoern Rupp, CEO, GSMK Cryptophone.

"With mobile phone interception technology now having come into the reach of regular criminals and amateurs using only commercially available PCs, relying on traditional security measures to protect private conversations is no longer a viable option. As effective countermeasures on the network side are not in sight, government departments and businesses alike need to implement robust policies and procedures to prevent confidential information falling into the wrong hands. With interception of mobile phone calls set to rise dramatically over the next five years, companies need a radical rethink on preventative measures to protect against external security threats," he added.
