1024-bit RSA encryption cracked by carefully starving CPU of electricity -- Engadget: "Now, three eggheads (or Wolverines, as it were) at the University of Michigan claim they can break it simply by tweaking a device's power supply. By fluctuating the voltage to the CPU such that it generated a single hardware error per clock cycle, they found that they could cause the server to flip single bits of the private key at a time, allowing them to slowly piece together the password."
