Abstract: A system and method for encrypting a data frame of a low-power communication protocol. The method includes providing an input data frame, the input date frame includes a random number, a unique identifier, and a payload data, encrypting the payload data, generating a Message Integrity Code (MIC), generating a rotating identifier by encrypting the unique identifier, and generating an output frame based on the generated rotating identifier, the generated MIC, and the encrypted payload data.
