Taliban using Skype phones to dodge MI6

Taliban fighters targeting British troops in Afghanistan are using the latest "internet phones" to evade detection by MI6, security sources said last night.

Skype, a popular piece of consumer software that allows free calls to be made over the web, has been adopted by insurgents to communicate with cells strung out across the country.

Unlike traditional mobile calls, which can be monitored by RAF Nimrod spy planes, Skype calls the commercial application of a technology called Voice Over Internet Protocol (VOIP) are heavily encrypted. Voice calls are broken into millions of pieces of data before being sent down the line and reassembled by the other callers computer.
