摘要： Systems and methods of generating a security key for an integrated circuit device include generating a plurality of key bits with a physically unclonable function (PUF) device. The PUF can include a random number generator that can create random bits. The random bits may be stored in a nonvolatile memory. The number of random bits stored in the nonvolatile memory allows for a plurality of challenge and response interactions to obtain a plurality of security keys from the PUF.

摘要： A filter request for a data set indicates a query specification and one or more sub-range indicators of a disjoint subset descriptor. Corresponding the individual data records obtained from the data set using the query specification, a respective range mapping value is generated. Using the range mapping values and the sub-range indicators, a result set of the filter request is obtained.

摘要： A universal interferometer for a three-dimensional quantum random number generator (3D QRNG) that includes three input ports. Each input port being configured to receive at least one prepared photon having three dimensions of quantum information in Hilbert space from a preparation stage of the 3D QRNG. The prepared photon is prepared based on a selected probability distribution set selected from probability distribution sets of p1, p2 and p3 that add to 1 and where the p1, the p2 and the p3 are rational numbers less than 1 and greater than zero. The universal interferometer includes three two-dimensional interferometers connected and arranged to measure along an x-axis of a Cartesian coordinate system the prepared photon and preserving the three dimensions of the quantum information of the measured photon. The universal interferometer includes three output ports which produces the measured photon corresponding to a three-dimensional eigenstate.

摘要： A card game for playing in a casino environment, with a dealer and one or more players. Before play commences the players place an ante bet. Each player and the dealer are then dealt 2 cards. The object of the game is to get a pair of cards scoring higher than the dealer, with a wild card being able to make a pair with any other card and two wild cards being the highest score possible. Without a pair the score is determined by the sum of the card's numeric values. Before the dealer reveals their cards, the players inspect their cards and can either forfeit their ante bet, or place a further bet equivalent to the original ante bet. A side bet is also available for receiving one or two wild cards.

摘要： A system for simulating a dataset based on sample statistics, and generating pipeline instructions for a database using the simulated dataset, is disclosed. The system may be a cloud-based platform. The system can provide improved performance and security while designing and deploying Extract-Transform-Load (ETL) database pipelines to manage on-premises data. The system receives, from a remote client, sample statistics characterizing a distribution of data corresponding to a column of a database table. The system can generate, based on the received sample statistics, a simulated dataset representing the column of the database table. The simulated dataset may be generated using pseudo-random data values from a distribution with statistics matching the sample statistics. The system can build a simulated database relation based at least in part on the simulated dataset. The system can generate and deploy pipeline instructions using the simulated database relation.

摘要： A message is embedded within an entropy stream. The message is encrypted using a onetime pad (OTP) and thus looks like part of the entropy string since the OTP encrypted messages is, as long as the “pad” material and message content are known, itself random to the observer. The encrypted message contains information used to identify and/or point to relevant information in another part of the entropy stream. For example, the OTP-encrypted message may indicate the number of units of the message, and point to a position in another part of the stream where another message is located. The stream may be randomly and deterministically expanded. Other techniques encrypt a stream using standard encryption, the stream comprising messages that are deterministically OTP encrypted; expand said encryption using a byte vector/array of randomness including at least one random vector; periodically swap out at least one member from the vector; hide vector random bytes in messages and/or using the messages to direct which bytes to remove from the stream of randomness/entropy; and store a stash of randomness separately from the messages and/or pull off the random/entropy stream as directed by the messages. By using true random and determinism, we create a method of generate a known pool of randomness that, if intercepted, cannot be discovered through mathematical analysis.
