Abstract: A method of enabling a communication channel between a first communication circuit and a second communication circuit is described. The method comprises establishing a communication link according to a communication protocol between the first communication circuit and the second communication circuit, wherein the communication protocol enables the transmission of data between the first communication circuit and the second communication circuit at a standardized data rate; determining a standardized data rate for which the communication link between the first communication circuit and the second communication circuit fails to meet a predetermined quality threshold; and establishing a communication link according to the communication protocol at a non-standardized data rate below the determined standardized data rate.

Abstract: A method, non-transitory computer readable medium, and apparatus for preventing accelerated aging of a physically unclonable function (PUF) circuit are disclosed. For example, the method monitors an environmental condition associated with the physically unclonable function circuit, detects a change in the environmental condition associated with the physically unclonable function circuit, and, in response to the change in the environmental condition, implements a security function for preventing the accelerated aging of the physically unclonable function circuit.
