KeyScaler®, a purpose-built IAM platform that focuses on device identity and is compatible with IoT/Blockchain, is available. It allows customers secure registration, provisioning, and connection of devices to IoT applications, platforms, and services. The platform makes it easy to establish a solid, end-to-end security architecture for the IoT. It also delivers efficiencies at scale via security automation without the need for human intervention. This is due to the IoT's dynamic scale, where new devices are being provisioned constantly, and it quickly becomes difficult to manage without automation. The IoT requires a method of identification that starts with individual devices. These devices can be authenticated automatically and dynamically without any manual intervention. Device Authority has created a flexible protocol for interface with KeyScaler®, which allows for the delivery of automated PKI for IoT device - offering two options for device authentication.
