Reporters obtained the following quote from the background information supplied by the inventors: "Microcontrollers may include a random number generator module. The random number generator module can generate random numbers based on an input from an entropy source. Variations in the entropy source may affect the randomness of the data generated by random number generator modules embedded in microcontrollers. Microcontrollers in the same series or from the same production lot may have fewer variations in their entropy sources and may exhibit less variation in the randomness in the data generated between random number generators included in microcontrollers in a series."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "A variable architecture for random number generators is disclosed. In some implementations, the architecture of a random number generator may be varied based on microcontroller-specific data stored on the microcontroller. For example, a random number generator module may be embedded in a microcontroller circuit. The random number generator module may be designed to receive input from data sources in the circuit that contain microcontroller-specific data (e.g., a unique chip identifier, data carried in fuse bits). In some implementations, the architecture of the random number generator module may be adjusted or varied based on the microcontroller-specific data.
"Particular embodiments can be implemented to realize one or more of the following advantages: (1) the randomness of numbers generated between random number generator modules in the same production series is improved; (2) power consumption related to generating random numbers is minimized; (3) the complexity of a production testing is minimized; and/or (4) production costs are reduced."
