Samsung patents chip part that makes secure random numbers
Samsung describes a hardware component designed to create true random numbers, which are essential for encryption. The device uses a specific type of diode with two gate regions doped with different materials to generate unpredictable electrical noise.
In the filing’s own words
A random number generation device includes at least one true random number generator, and the at least one true random number generator includes a gated diode including first and second gate regions disposed on an intrinsic region and doped with different dopants and first and second gate electrodes respectively stacked on the first and second gate regions and a resistor connected in series to the gated diode. A crypto system includes the random number generation device.
What exactly they claim (claim 1)
1. A random number generation device comprising at least one true random number generator, the at least one true random number generator comprising: a gated diode including a first region, a second region, an intrinsic region between the first region and the second region, a first gate region on the intrinsic region and doped with a first dopant, a first gate electrode on the first gate region, a second gate region on the intrinsic region, wherein the second gate region is arranged side by side with the first gate region and is doped with a second dopant having characteristics different from characteristics of the first dopant, and a second gate electrode on the second gate region; and a resistor electrically connected in series to the gated diode.
