Congress should consider the Internet of Things -- the rapidly growing network of devices, objects and sensors -- as it debates whether to help law enforcement access encrypted communications, Rep. Darrell Issa, R-Calif., said Wednesday. Within our lifetime, citizens will be in regular contact with millions of microprocessors, the Republican congressman told a small audience on Capitol Hill. (Gartner has predicted 21 billion devices will connect by 2020). "Will they be connected or completely vulnerable?" Issa said. "Will they be encrypted? Will there have to be a backdoor? Those questions and more very clearly fall within the debate we have to have in Congress."
