factories. The objective of secure manufacturing is to ensure that OEM devices are manufactured per OEM specification of hardware, firmware and data, and without loss of any OEM IP. Secure manufacturing processes also are designed to authenticate ICs for silicon-vendor proof of origin prior to provisioning to prevent the production of counterfeit or fraudulent devices.


Building security and trust into devices To implement supply chain integrity and secure manufacturing requires building security and trust into devices with hardware-based security. To achieve this, a number of key building blocks must be put in place. First, OEMs must use securable IC elements or microcontroller units (MCUs) with storage protected by a hardware- based root of trust and a trusted execution environment. These elements or MCUs also must provide an immutable boot path and true random number generation mechanism to enable generation and usage of a unique device identity. While use of secure elements or units is


necessary to secure the end device, additional operations must be performed to further build on and enhance the security that is provided by the hardware-based roots of trust. This is accomplished in manufacturing through the process of secure provisioning that configures the hardware roots of trust on a device and, hence, creates the device identity and device-specific security credentials, binding these security elements to the IC responsible for securing the device. Security credentials like keys, certificates, chain of trust, firmware


Authentication of ICs before provisioning Data I/O has developed the SentriX security deployment-as-a- Service platform to deliver on the promise of secure manufacturing. Using SentriX, OEMs now have the ability to secure their supply chain and manufacture secure devices at scale – without risk of counterfeit production – using a trusted security deployment service. To prevent production of counterfeit or inferior devices, SentriX programming processes are designed to authenticate ICs for silicon- vendor proof of origin prior to provisioning additional security credentials into the device. Secure element ICs and MCUs provide a secure cryptography-based authentication process that is based on a silicon-vendor IC identity certificate that is pre- provisioned into the IC during the manufacturing process. During the SentriX authentication process for individual ICs, a silicon vendor ID, a product ID and a serial

number are read from the IC and compared against a list of such data provided by the silicon vendor. If the data read from the IC is not found in the list provided by the silicon vendor, the device is marked as counterfeit and


eliminated from the manufacturing process. SentriX is designed with the paramount goal of


securing and simplifying the IC provisioning process and


and data that are provisioned into a device IC are very important secrets for an OEM. Should a bad actor gain access to these security credentials during the manufacturing process, the security deployed into devices can be compromised. Thus, in order to protect the security credentials that need to be provisioned into devices during manufacturing, it is fundamental that the deployment process itself be secure.


helping eliminate the risk of counterfeit devices entering the market. The SentriX security deployment platform helps OEMs overcome key challenges of device security definition, secure manufacturing and the secure provisioning of trust into devices during manufacturing for improved security, lower cost, faster time to market and greater supply chain integrity.
