Generating and Using Ephemeral Identifiers and Message Integrity Codes |
摘要 |
Systems and methods for generating and using ephemeral identifiers are provided. One example method includes determining, by one or more computing devices, a current time-count. The method includes determining, by the one or more computing devices, a time-modified identifier based at least in part on a static identifier and the current time-count. The method includes determining, by the one or more computing devices, an ephemeral identifier based at least in part on the time-modified identifier and a rotation key. One example system includes a plurality of beacon devices, at least one observing entity, and at least one verifying entity. |

1. A computer-implemented method for authenticating beacon devices, the method comprising:
receiving, by one or more computing devices, a static identifier and a message integrity code from an observing entity, the observing entity having previously received the static identifier and the message integrity code from a beacon device, wherein the message integrity code comprises a time-varied obscuration of the static identifier associated with the beacon device; determining, by the one or more computing devices, a validity of the message integrity code by matching the message integrity code versus a plurality of expected message integrity codes; and when the message integrity code is determined to be valid, providing, by the one or more computing devices, the observing entity with an authentication of the beacon device. |
