Patent attributes
An authentication system and method for authenticating an asset includes a Near Field Communication (NFC) tag associated with the asset, an NFC enabled user device, and an authentication server. The NFC tag includes a unique identifier and an encrypted output of a shared key that is stored on the authentication server. The encrypted output includes a Speck cryptographic algorithm. The unique identifier and the encrypted output are signed by an Elliptic Curve Digital Signal Algorithm (ECDSA) signature. When the user device verifies challenge/response messages and the unique identifier, and the ECDSA signature is verified by either the user device or the authentication server, the encrypted output is decrypted and the authentication server compares the decrypted data with the stored shared key to either determine that the asset is authentic or notify a stakeholder associated with the asset that the asset is inauthentic.
