Abstract: Disclosed is a software PUF based on an RISC-V processor for IoT security. A 32-bit RISC-V processor is used to generate abnormal information results in an abnormal operating state under a low voltage, and the abnormal information results are used to represent the features of the 32-bit RISC-V processor; 5-bit binary data obtained by comparing the abnormal information results with normal information results has high randomness and uniqueness and it is extremely difficult to directly extract internal abnormal information result from a hardware circuit of the 32-bit RISC-V processor, so modeling attacks based on the 5-bit binary data calculated according to the abnormal information results of the 32-bit RISC-V processor are almost impossible; in addition, when the 32-bit RISC-V processor is in an abnormal operating state, the operating frequency of the 32-bit RISC-V processor is dynamically adjusted through a frequency compensation method.

Abstract: This application provides a HARQ feedback method and an apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates a first quantity of retransmissions of first data. The terminal device obtains a second quantity of retransmissions based on a HARQ feedback result and/or a decoding result of second data, where the second data is data retransmitted by the terminal device before the terminal device retransmits the first data. The terminal device sends the first data by using a target quantity of retransmissions, where the target quantity of retransmissions is a smaller one of the first quantity of retransmissions and the second quantity of retransmissions. According to the method, data transmission is performed by using the determined target quantity of retransmissions, so that a delay caused by a HARQ can be reduced, resources can be saved, and power consumption can be reduced.

Abstract: Machine learning, artificial intelligence, and other computer-implemented methods are used to identify various semantically important chunks in documents, automatically label them with appropriate datatypes and semantic roles, and use this enhanced information to assist authors and to support downstream processes. Chunk locations, datatypes, and semantic roles can often be automatically determined from what is here called “context”, to wit, the combination of their formatting, structure, and content; those of adjacent or nearby content; overall patterns of occurrence in a document, and similarities of all these things across documents (mainly but not exclusively among documents in the same document set).

Abstract: A communication router and hub are provided. In examples, a communication platform enables communication between a customer and a service. Customer information associated with a customer is stored as part of a customer record.
