Reverse Engineering

(1) A process used by counterfeiters to make a cloned part. (2) The process of discovering the technological principles of a device through analysis of its structure, function, and operation. (3) The disassembling of an electronic component to analyze its inner workings in detail for the creation of a new device that will either function the same. See: Recycled Part, Remarked Part, Overproduced Part, Out-of-spec Part, Cloned Part Note: Part cloning may involve reverse engineering. “Cloning is commonly used by a wide variety of adversaries/counterfeiters (from small entity to large corporation) to copy a design in order to reduce the large development cost of a component. A cloned component is an unauthorized production without a legal IP. Cloning can be done in two ways – by reverse engineering, and by obtaining IPs illegally. In reverse engineering, counterfeiters copy designs and then manufacture (fabricate) components which are the exact copy of their original counterpart. Sometimes cloning can be done by copying the – contents of a memory used in a tag for electronic chip ID, bitstream targeted to programmable gate arrays, etc.” "
