Mark Wilson writes that Apple has balked at a court order to provide the FBI with the contents of text messages among users of its iMessage service, claiming that the encryption it uses to protect these messages makes handing over the messages themselves impossible. From the article:The Justice Department obtained a court order that required Apple to provide real time access to text messages sent between suspects in an investigation involving guns and drugs. Apple has responded by saying that the fact iMessage is encrypted means that it is simply not able to comply with the order. The stand-off between the US government and Apple could last for some time as neither side is willing — or possibly able — to back down.
