Abstract: According to some embodiments, a system may include a communication port to exchange information with a client device associated with an industrial control system. A network security server coupled to the communication port may include a computer processor adapted to provide a network security service for the client device. The computer processor may further be adapted to record security information about the client device via a blockchain verification process (e.g., by registering a validation result within a distributed ledger). The network security service might comprise, for example, an integrity attestation service providing software verification for the client device.

Abstract: Some aspects are directed to additive manufacturing systems. An example additive manufacturing system controller is configured to receive a build file comprising instructions for controlling the manufacturing hardware to generate the object, receive a material identifier indicating a particular lot of manufacturing media, validate the build file and the material identifier via a distributed ledger to verify at least one of an author of the build file or an origin of the particular lot of manufacturing media, control the manufacturing hardware using the build file to generate the object using the particular lot of manufacturing media, and in response to completion of the generation of the object, generate an object manufactured transaction to the distributed ledger indicating a result of the validation of the origin of the at least one of the build file or the material identifier.
