This tiny chip could revolutionize smartphone and IOT security

Engineers at South Korea's SK Telecom have developed a tiny chip that could help secure communications on a myriad of portable electronics and IOT devices.The chip is just 5 millimeters square -- smaller than a fingernail -- and is capable of generating mathematically provable random numbers. Such numbers are the basis for highly-secure encryption systems and producing them in such a small package hasn't been possible until now.The chip, on show at this week's Mobile World Congress in Barcelona,
