Device authentication using light-based communications and configurable surfaces

A non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device:

• to obtain at least one authentication request comprising at least one identifier of at least one device;
• to generate at least one control signal to configure one or more characteristics of a configurable surface located in a physical environment based at least in part on the at least one identifier of the at least one device;
• to emit, in the physical environment, at least one encoded message for the at least one device using one or more light sources;
• to modify the emitted at least one encoded message using the configurable surface based at least in part on the at least one control signal;
• and
• to determine whether to authenticate the at least one device based at least in part on information transmitted by the at least one device in response to the at least one message.

An apparatus comprising:

• at least one processing device comprising a processor coupled to a memory;
• the at least one processing device being configured:
• to obtain at least one authentication request comprising at least one identifier of at least one device;
• to generate at least one control signal to configure one or more characteristics of a configurable surface located in a physical environment based at least in part on the at least one identifier of the at least one device;
• to emit, in the physical environment, at least one encoded message for the at least one device using one or more light sources;
• to modify the emitted at least one encoded message using the configurable surface based at least in part on the at least one control signal;
• and
• to determine whether to authenticate the at least one device based at least in part on information transmitted by the at least one device in response to the at least one message.
