Backdoor (computing)
A backdoor is a method, often secret, of bypassing normal authentication or encryption in a computer system, a product, or an embedded device (e.g. a home router), or its embodiment, e.g. as part of a cryptosystem, an algorithm, a chipset, or a "homunculus computer" (such as that as found in Intel's AMT technology).
