摘要： The disclosure discloses a method for constructing actual processing curve of part with small curvature based on a point cloud boundary. The method includes: (a) encrypting a three-dimensional ordered boundary curve of a part to be processed; (b) fitting encrypted boundary points into a plane, and projecting each boundary point into the plane to obtain a projection point; (c) performing Euclidean cluster within the plane to obtain point sets, and fitting the obtained point sets into a straight line; (d) performing the Euclidean cluster on projection points that are not fitted into the straight line to obtain corner point sets, and fitting a sharp corner or a rounded corner of the corner point sets to obtain a fitted boundary curve within the plane; (e) mapping the fitted boundary curve to a curved surface of the three-dimensional ordered boundary curve to obtain an actual processing curve of the part to be processed.

摘要： Disclosed herein is a system for providing a cryptographic platform for distributing data structures within a peer-to-peer network wherein encrypted messages are exchanged among nodes. The system provides for the creation and management of privately subspaced blockchains that include subspaces that are private, yet verifiable through the use of global state roots. The global state roots are updated based on subspace roots that are in term generated based on the data in that subspace.

摘要： A device which can be implemented on a single packaged integrated circuit or a multichip module comprises a plurality of non-volatile memory cells, and logic to use a physical unclonable function to produce a key and to store the key in a set of non-volatile memory cells in the plurality of non-volatile memory cells. The physical unclonable function can use entropy derived from non-volatile memory cells in the plurality of non-volatile memory cells to produce a key. Logic is described to disable changes to data in the set of non-volatile memory cells, and thereby freeze the key after it is stored in the set.

摘要： An information processing device includes: a storage that stores execution reservation information transmitted from a user server, wherein the execution reservation information represents an execution reservation of acceptor servers that execute first tasks that have been encrypted and divided; and a processor that: receives a second task from the user server, encrypts and divides the second task to generate the first tasks, requests the acceptor servers to execute the generated first tasks based on the execution reservation information stored in the storage, receives first execution results from the acceptor servers, decrypts and combines the first execution results to generate a second execution result, and transmits the generated second execution result to the user server.

摘要： A data partition unit partitions character string data D into N pieces of element data w1, w2, . . . , wN from a front to an end of the character string data D. A partial character string generation unit generates a set A={A1, A2, . . . , AN} and an element Ai={(wi), (wiwi+1), . . . , (wiwi+1 . . . wN)} of the set A where i=1, . . . , N, from the element data w1, w2, . . . , wN. A position information assignment unit generates a set B={B1, B2, . . . , BN} and an element Bi={(i, wi, (i, wiwi+1), . . . , (i, wiwi+1 . . . wN)} of the set B by associating each of (wi), (wiwi+1), . . . , (wiwi+1 . . . wN) which are components of the element Ai with position information i. An encryption unit encrypts each of (i, wi), (i, wiwi+1), . . . , (i, wiwi+1 . . . wN) which are components included in the element Bi.

摘要： In some implementations, a scheme for data communication in an automobile includes generating a cleartext message to be transmitted to a second ECU, generating a pseudo-random counter by applying a pseudorandom function to a counter value that is incremented for each cleartext message generated by the ECU; combining the cleartext message and the pseudo-random counter to create a randomized message; selecting from a plurality of available cryptography techniques, a selected cryptography technique; applying to the randomized message, the selected cryptography technique to create a ciphertext; and transmitting to the second ECU over the CAN bus, the ciphertext.

摘要： A method of operating at least one node in a communication network that uses a shared communication medium has been developed. The method includes adjusting, with a controller in a first node, a resistance of a first potentiometer in the first node to a first resistance level that the controller in the first node determines randomly, the first potentiometer in the first node being connected to an output of a transceiver in the first node and to a shared communication medium, and transmitting, with the transceiver in the first node, a first data bit through the output that is connected to the shared communication medium with the first potentiometer producing the first resistance level.

摘要： A key based technique that targets obfuscation of critical circuit parameters of an analog circuit block by masking physical characteristics of a transistor (width and length) and the circuit parameters reliant upon these physical characteristics (i.e. circuit biasing conditions, phase noise profile, bandwidth, gain, noise figure, operating frequency, etc.). The proposed key based obfuscation technique targets the physical dimensions of the transistors used to set the optimal biasing conditions. The widths and/or lengths of a transistor are obfuscated and, based on an applied key sequence, provides a range of potential biasing points. Only when the correct key sequence is applied and certain transistor(s) are active, are the correct biasing conditions at the target node set.
