Millions of mobile phones may be vulnerable to spying due to the use of outdated, 1970s-era cryptography, according to new research due to be presented at the Black Hat security conference.

Nohl's research looked at a mobile phones' SIM (Subscriber Identification Module), the small card inserted into a device that ties it to a phone number and authenticates software updates and commands sent over-the-air from an operator.
More than 7 billion SIM cards are in use worldwide. To ensure privacy and security, SIM cards use encryption when communicating with an operator, but the encryption standards use vary widely.
A mobile communication trade group, the GSM Association, said in a statement that only a "minority" of SIM cards that use older encryption standards would appear to be vulnerable.
"There is no evidence to suggest that today's more secure SIMs, which are used to support a range of advanced services, will be affected," GSMA said.
