New Hardware-based Security Solution Helps Secure IoT Devices at the Silicon Level
The IoT can arguably be defined in two categories: low capacity small embedded things (like sensors within an industrial control environment), and more powerful edge devices (like routers, smart TVs, in-car entertainment systems and so on). According to Gartner, there will be 30 billion IoT devices in use by 2020, and according to Statista, this will grow to almost 75.5 billion by 2025. Both categories, intelligent edge devices and dumb sensors, require better security than most currently receive.
The market growth figures demonstrate, however, that the greatest number of IoT devices that will be in use within the next few years are yet to be deployed. This provides the opportunity to secure the future IoT if action is taken now. This is where the difference between the low capacity sensor-type IoT devices and the greater capacity edge devices becomes important. The former cannot contain security, and require security to be layered around the embedded devices. The latter, however, have sufficient capacity to contain their own security.
It is for this latter category of edge devices that Micron has announced a new silicon-based security-as-a-service platform for edge devices -- the Authenta Key Management Service. The service starts with the device manufacturer who installs Micron's latest Authenta flash, which uses existing standard non-volatile memory (NVM) sockets. The new key management Authenta can either leverage available slots, or replace older Authenta flash memory -- it does not require device manufacturers to re-engineer the hardware.
The new service, says Micron, "allows installed Authenta-enabled devices to be switched on through a cloud-based service, mitigating some of the biggest challenges and complexities related to securing devices in an 'everything connected' environment." Current methods of securing these devices have limitations. ..
