NEW YORK - The Obama administration is leading a global effort to deploy "shadow" Internet and mobile-phone systems that dissidents can use to undermine repressive governments that seek to silence them by censoring or shutting down telecommunications networks. The effort has quickened since former Egyptian President Hosni Mubarak's government shut down the country's Internet in the last days of his rule, said the Times report, citing planning documents, classified diplomatic cables and sources. The Internet has been used in recent months by anti-government protesters in Africa and the ME to help coordinate demonstrations. Some govts have responded by disabling Internet access. In one project, the US State Department and Pentagon have spent at least $50 million to create an independent cell phone network in Afghanistan using towers on military bases in the country, the Times said, citing unnamed US officials. The operation is aimed at counteracting the Taliban insurgency's ability to shut down official Afghan services, the Times said. The State Deptt is also financing creation of stealth wireless networks to enable activists to communicate beyond the reach of govts in countries like Iran, Syria and Libya, Times said. Another project focuses on development of an "Internet in a suitcase" that could be smuggled across a border and deployed to allow wireless communication with a link to the global Internet, the Times reported. Secretary of State Hillary Clinton is backing the US effort, according to the report. "We see more and more people around the globe using the Internet, mobile phones and other technologies to make their voices heard as they protest against injustice and seek to realize their aspirations," the Times quoted Clinton as saying in an email response to a query on the subject. US diplomats also are meeting with operatives who have been burying Chinese cellphones near the border with North Korea, where they can be dug up and used to make furtive calls, the Times reported.
