theodp writes "Technology Review's David Talbot says IT's next grand challenge will be to secure the cloud — and prove we can trust it. 'The focus of IT innovation has shifted from hardware to software applications,' says Harvard economist Dale Jorgenson. 'Many of these applications are going on at a blistering pace, and cloud computing is going to be a great facilitative technology for a lot of these people.' But there's one little catch. 'None of this can happen unless cloud services are kept secure,' notes Talbot. 'And they are not.' Fully ensuring the security of cloud computing, says Talbot, will inevitably fall to emerging encryption technologies."
