"This article in the NYTimes discusses how a recent rash of high-profile mobile phone taps in Italy is spurring a rush toward software-encrypted phone conversations. Private conversations have been tapped and subsequently leaked to the media and have resulted in disclosures of sensitive takeover discussions, revelations regarding game-fixing in soccer, and the arrest of a prince on charges of providing prostitutes and illegal slot machines. An Italian investigative reporter stated that no one would ever discuss sensitive information on the phone now. As a result, encryption software for mobile phones has moved from the government and military worlds into the mainstream. Are GSM phones in the US ripe for a similar explosion in the use of freely available wiretapping technology, and could this finally be the impetus to for widespread use of software-encrypted communications?"
I wonder how many business deals a day are conducted via cell phones.
