With the IOT craze comes the need to securely identify remote devices so that no one should be turning on your lights and other gadgets at wee hours. Many companies are trying to remotely generate and quirt digital certificates into IoT devices but can't tell if the right devices are receiving the identities or worse, don't even know if the same key is being illegally cloned into other units by some subcon trying to channel into black markets. So you think you are turning on your ceiling fan and all of a sudden all of Bahrain lights up, sort of cool in a crass way if you are not on the receiving end. (Of course Atmel's ATECC508A totally solves this problem). How are you (or your customers) tackling the problem of IoT device identification for cloud connectivity today?
