Abstract
A device and method provide a visible or audible indication of whether an integrated circuit (IC) is authentic using cryptographic hashes stored on a blockchain. The IC includes a cryptographic mining circuit that creates blocks for storage in the blockchain. Each such block includes the value of a cryptographic hash function applied to a serial number unique to the IC and the hash value most recently stored in the blockchain. The necessary data are communicated between the IC and a blockchain server by an intermediary electronic authentication device, which also receives data from the server that indicate whether the second hash value equals an expected hash value computed by (or provided to) the server. The electronic authentication device accordingly provides a suitable visible or audible message to a user.
