At the core of lightweight applications, such as medical implant devices, are the batteries that power them and the success of the device rests heavily on them. This Trojan drains the battery once it gets activated. The Trojan gets activated after observing a predefined input plaintext. The Trojan payload is a shift register which continuously rotates after Trojan activation. The Trojan increases the power consumption and hence decreases the expected lifetime of the battery.
