  • Secure device ownership transfer using an ephemeral device transfer token generated using elliptic curve cryptography
    Patent number: 11190346
    Abstract: One or more device(s) is identified for which ownership of the device(s) is to be transferred from an identified transferor system to an identified transferee system. An ephemeral device transfer token is generated for the transferor using an elliptic-curve Diffie-Hellman cryptographic function, wherein the ephemeral device transfer token is only valid over a limited period of time to authorize a transfer of ownership of the device from the transferor to the transferee. The transferor then delivers the ephemeral device transfer token to the transferee. A device ownership record may be modified to transfer ownership of the device from the transferor to the transferee in response to receiving the ephemeral device transfer token from the transferee during the limited time period.
