Internet of Things require a new security model instead of normal model for PCs and smartphones, in order to take off, says top US defence official.
Speaking at Gigaom's Structure conference in San Francisco, US Defense Advanced Research Projects Agency (DARPA) director of the Information Innovation Office Dan Kaufman said model applied to PCs and smartphones may not be feasible in embedded systems.
PCs and smartphones may start installing security patches or updates once they are switched on but they may not work in an embedded system.
Kaufman said: "If we don't have a fundamentally new security model, then I don't know how we're going to enjoy the Internet of Things. Patch Tuesday for your car or your insulin pump doesn't make a whole lot of sense."
Keeping in view of the risks, DARPA is currently developing an 'unhackable' operating system for embedded systems.
The new system will use 'homomorphic encryption' instead of standard encryption, which will make the data encrypted even when it is being used, making difficult for hackers to crack.
He added that the growth internet of things and the hyper-connected could pose greater risk to people, as hackers could now access data as well as take control of people's physical world.
