摘要： Embodiments include method, systems and computer program products for extracting entropy from mobile devices to generate random numbers. In some embodiments, first vibration data may be received from a first device. Second vibration data may be received from a second device. A first piece of entropy data may be generated using the first vibration data and a second piece of entropy data may be generated using the second vibration data. The first piece of entropy data and the second piece of entropy data may be aggregated. The first piece of entropy data and the second piece of entropy data may be stored in an entropy pool.

摘要： A method determines the connectivity components defined by a set of relations over a set of data elements. For each first data element of a selected subset of data elements, a second data element that is linked to the first data element by a path of relations is selected as its representative, using a randomization process. A new set of relations is created by replacing each first data element of the subset by its representative in at least part of the set of relations.

摘要： According to one embodiment, a permutation generator is described comprising a memory configured to store, for each number of a predetermined set of numbers, whether the number has already been included in a number sequence; a receiver configured to receive a random number; a determiner configured to select a number from those numbers of the set of numbers that have not yet been included in the number sequence as next element of the number sequence based on the random number and an output configured to output the selected number as the next element of the number sequence.

摘要： This disclosure describes techniques for analyzing statistical quality of bitstrings produced by a physical unclonable function (PUF). The PUF leverages resistance variations in the power grid wires of an integrated circuit. Temperature and voltage stability of the bitstrings are analyzed. The disclosure also describes converting a voltage drop into a digital code, wherein the conversion is resilient to simple and differential side-channel attacks.

摘要： A method for generating a random number for use in a stochastic rounding operation is provided. The method includes executing an instruction that causes at least two operands to produce an intermediate result and incrementing a state of a random number generator. The method d further includes causing the random number generator to generate a random number in accordance with the state and producing a final result by utilizing the random number to determine a rounding of the intermediate result.

摘要： An instruction configured to perform a plurality of functions is executed. Based on a function code associated with the instruction having a selected value, one or more inputs of the instruction are checked to determine which one or more functions of the plurality of functions are to be performed. Based on a first input of the one or more inputs having a first value, a function of providing raw entropy is performed, in which the providing of raw entropy includes storing a number of raw random numbers. Further, based on a second input of the one or more inputs having a second value, a function of providing conditioned entropy is provided, in which the providing of conditioned entropy includes storing a number of conditioned random numbers.
