An algorithm from the 1990s used to encrypt mobile phone data was deliberately weakened to allow eavesdropping, claims a team of cryptanalysts. It is possible the flaw could still allow access to some phones in use today.
“It’s a nice weakness, from a technical point of view. But it’s still not good to build it. Probably many people were involved,” says Christof Beierle at Ruhr University Bochum in Germany, part of the team …
