Abstract: In today’s diverse manufacturing, logistics and just-in-time (“JIT”) inventory environment, assurance of a device’s origin and subsequent history has become a critical challenge. Each asset in PCB assembly could have a unique, virtual Identifier that points back to a source (for example, see SEMI E142 Substrate Mapping Standard used during chip manufacturing) that is used to track its journey through the supply chain. These virtual Identifiers may be stitched together into a thread which is cryptographically anchored at certain points to form a Platform Root of Trust. This presentation will show how a virtual identifier thread, coupled with a distributed ledger such as blockchain, the root of trust technologies and advanced analytics can achieve the reliability and security demanded by today’s applications. A simple example of the utility of this traceability of the parts and supply chain will be discussed. A virtual identifier could enable the automatic generation of a bill of materials (including firmware) and a platform level certificate traceable to the physical parts and identifiers.
Bio: Tom Dodson received his Bachler of Computer Science from the California State University Sacrament where he focused on Hardware Design and Manufacturing. Tom has been working for Intel Corporation for the past 26 years in the Supply Chain and Manufacturing field working with component suppliers and system manufacturers in the US and Asia to ensure a secure and healthy supply chain has been established. Over the last seven years, Tom has developed a set of Trusted Supply Chain Policies and Procedures, working with NIST and TCG to establish standards that can be used across the industry. For the last 2 years Tom has been leading GSA Trusted IoT Ecosystem Security solutions (TIES) M345 working group focusing on PCB and System to develop whitepapers focusing on PCB / Component Root of Trust and Traceability using Blockchain
