    Abstract: A method for non-orthogonal multiple access (NoMA) transmission is provided. In an embodiment, a method in a network device for transmission of a NoMA signal includes obtaining information bits. The method also includes transmitting the NoMA signal. The NoMA signal includes one or more layers. The NoMA signal is generated according to the information bits and according to a set of signal processing operations selected from a plurality of signal processing operations. At least one of the set of signal processing operations is layer-specific or UE-specific or a combination thereof.

    Abstract: An embodiment of the present application provides technologies for detecting malicious content embedded in a content downloaded from an external source. The downloaded content converted into an opcode sequence by a web browser in a computing device. The opcode sequence is compared with a pre-stored opcode signature. The opcode signature comprises multiple sentences, and each sentence has multiple clauses. Each clause may include a matching opcode, a condition, an instruction, and an identifier. When a matching opcode in a clause matches with an opcode of the opcode sequence, and the condition as specified in the clause is determined to be true, the instruction in the clause is taken and next sentence identified by the identifier is taken to match the opcode sequence. Eventually, the last taken clause in the opcode signature may instruct whether opcode sequence contains malicious code.

    Abstract: Embodiments of this application disclose a software integrity protection method and apparatus. A first device obtains a first software package, where the first software package includes a first signature made by a first party for a second software package by using a first private key; and the first device performs a signing operation on the first software package by using a second private key, to obtain a third software package including a second signature, where the first private key is controlled by the first party, and the second private key is controlled by a second party. The first device sends the third software package to a second device. The second device verifies the first signature and the second signature in the third software package respectively based on a first public key and a second public key that are prestored, to obtain a verification result.
