1. A method comprising:
executing, by data processing hardware, a clock for an operation period starting at a first time and ending at a final time; receiving, at the data processing hardware, a communication from a remote device at a communication time corresponding to a time interval of a plurality of time intervals sequentially covering the operation period, each time interval having an associated authentication value, and the communication comprising a commitment value; determining, by the data processing hardware, whether the commitment value matches the authentication value associated with the time interval corresponding to the communication time; and processing the communication at the data processing hardware when the commitment value matches the authentication value associated with the time interval corresponding to the communication time, wherein the authentication value associated with the time interval corresponding to the communication time comprises a hash digest of a hash function applied to the authentication value associated with a sequentially subsequent time interval of the plurality of time intervals. |
