In order for IoT to be distributed to households in bulk, it must solve IoTCAS.
IoTCAS : Internet of Things Cost Availibility Security Issue IoT stands for Internet of Things. According to a 2016 IHS survey, 30 billion IoT Edge devices will be connected in 2020. But why is the supply of IoT slow? It's because of the IoTCAS. IoTCAS stands for Cost, Availability, and Security, which are problematic for the dissemination of IoT. Price, convenience and security issues in Korean. In fact, all three of these problems come from one, and the part related to convenience is to make up UI / UX, so it can be solved somehow, but there is a conflict between the Cost and Security parts. In other words, increased security means higher prices and lower prices mean less security. However, security becomes a very important IoT element in the world. For example, in the case of a door lock, the price of the circuit material should be very low, but it requires top-level security. In fact, it's not fun for someone, whether it's Smart Home or Industrial IoT, to have a hacker
