1. An apparatus, comprising:
a communications interface;
a memory storing instructions; and
at least one processor coupled to the communications interface and to the memory, the at least one processor being configured to execute the instructions to:
receive, via the communications interface, message data associated with an inquiry from a first computing system, the message data comprising encrypted interlaced data, an identifier, and temporal data;
determine that a structure of the message data corresponds to an expected structure, and based on the determination that the structure of the message data corresponds to the expected structure, perform operations that generate a decryption key based on at least one of the identifier or the temporal data, and that decrypt the encrypted interlaced data using the decryption key, the decrypted interlaced data comprising inquiry data characterizing the inquiry and dummy data;
based on a portion of the decrypted interlaced data, transmit, via the communications interface, a request for a response to the inquiry to a second computing system;
receive, via the communications interface, the response to the inquiry from the second computing system; and
transmit, via the communications interface, at least a portion of the response to the first computing system, the first computing system being configured to present the portion of the response within a digital interface.
