Techniques for identifying vulnerabilities in binary files using a code signature are disclosed. In some embodiments, a system, a process, and / or a computer program product for identifying vulnerabilities in binary files using a code signature includes collecting a plurality of binary files associated with a vulnerability (e.g., a known vulnerability); determining a function in the plurality of binary files that includes the vulnerability; and automatically generating a code signature (e.g., including wildcarding one or more instructions of the function) for detecting the vulnerability in the plurality of binary files.

Aspects of the disclosure relate to a multipoint environment that enables a station (STA) to communicate with multiple access points (APs) and an AP to communicate with multiple STAs in a single wireless protocol stack. For example, a STA can authenticate simultaneously with multiple APs and decode any data packet that includes in a header a destination address that matches an address of the STA, irrespective of the source address included in the header of the data packet. Similarly, an AP can decode any data packet that includes in a header a destination address that matches an address of the AP or that matches a wildcard address associated with the AP, irrespective of the source address included in the header of the data packet.

The application provides a character search method and device of an input method program, an electronic device, a computer readable storage medium and a computer program product. The method comprises: obtaining a query request input in the input method program, wherein the query request comprises at least one character string and at least one wildcard, and each wildcard is used to replace at least one omitted character string; determining the order of a first character string in the query request and the first number of character strings omitted before the first character string; determining a level corresponding to the order from a plurality of index trees of a first word library, wherein each node of each level comprises an index character string and an index number; querying a first candidate node matching the first character string and the number from at least one node included in the level; and determining a first candidate character string to be output based on the first candidate node. Through the application, the retrieval efficiency in a fuzzy input scenario can be improved.

In examples, a query management system maintains a query schema for a structured data source. The query schema includes a collection of query templates, where each query template specifies at least one condition. When a mutation in an underling data source is detected, the query management system generates an invalidation command for a corresponding set of cached keys. Based on attributes of the mutated data set, the query template can enable the use of wildcard designations to for purpose of identifying cache keys that are to be invalidated as a result of the mutated data set.

This invention provides a method and apparatus for disseminating information on variable message signs (VLDLs). The method is executed by a roadside unit equipped with a VLDL controller and an information generator. The method includes: the information generator receiving a signature template corresponding to a VLDL information dissemination request from a management unit, and obtaining parameter variables corresponding to the signature template; wherein the VLDL information dissemination request is used to determine the VLDL information dissemination template type, and the VLDL information dissemination template includes template validity information and dissemination content containing wildcards, where the wildcards are placeholders for specific parameter variables; the VLDL controller performs digital signature verification and template validity verification on the signature template, and upon successful verification, matches the obtained parameter variables with the wildcards in the signature template, thereby updating the signature template based on the matched parameter variables, so that the VLDL display screen shows the information in the updated signature template. This invention ensures the security of VLDL information dissemination.

This application discloses an FRP remote access system, method, server, storage medium, and product. The system includes: a master control device, a public network server, and multiple controlled devices. The master control device sends network service request messages to the FRP server on the public network server. A preset field in the network service request message contains a unique identifier for the controlled device; this preset field is a field excluding the HOST field in the network service request message. The FRP server parses the unique identifier of the controlled device from the network service request message, determines the target controlled device based on the unique identifier of the controlled device and the unique identifier contained in the custom domain name of each controlled device, and forwards the network service request message to the target controlled device for accessing the network server on the controlled device. This achieves access to the network server of the target controlled device without using wildcard domain names, reducing software development costs and program development difficulty.

The application provides a tightening method and device applied to a vehicle assembly process, and belongs to the technical field of vehicle assembly. The method comprises the following steps: a current tightening tool obtains a vehicle type identification code of a current vehicle; a target wildcard matching rule that is consistent with the vehicle type identification code is matched from a wildcard matching rule set of the current tightening tool; a target vehicle type of the current vehicle is determined according to the target wildcard matching rule; and the current tightening tool is controlled to perform a tightening operation on the current vehicle according to the target vehicle type. The application sets a corresponding wildcard matching rule set in advance for different tightening tools, sets a corresponding vehicle type by setting the wildcard matching rule, greatly reduces the number of vehicle types, supports the expansion of more vehicle type characteristics, and makes the setting and maintenance management of the tightening program more convenient.

Controlling access to at least one domain associated with an access point using a wildcard-free certificate and an allow list is described. Relationship data describing how data is to be routed between an access point and domains is received. Based on the relationship data, a certificate is generated that individually lists each domain associated with the access point and includes information describing data routing for the domain via the access point. Data describing at least one exception for granting a request, when the request does not specify a domain included in the wildcard-free certificate, is received and used to generate an allow list. The certificate and the allow list are used to control data communication traffic via the access point.

The present application belongs to the technical field of industrial internet of things communication and terminal access configuration, and discloses a DTU logic control system and method supporting one-key cloud configuration. The DTU establishes a local maintenance channel through an embedded Web configuration service, issues a visual page to obtain cloud access parameters, writes the parameters into a non-volatile storage area after verification to form a persistent configuration, reads the configuration after restart or exit from the configuration mode, parses the communication protocol type, instantiates the corresponding network protocol stack, and completes the connection and authentication with the cloud platform. The present application introduces a hardware fingerprint dynamic binding process, uses a unique device identifier to replace a wildcard in a configuration template to generate a dedicated communication identifier, and uses a dual-partition storage of a running partition and a candidate partition and an automatic rollback strategy for trial operation. When the connection fails for more than a threshold value, the system is restored to a historical effective configuration, realizes parameter and firmware decoupling, visual configuration, and automatic recovery in an unattended scenario, and improves the deployment efficiency and operation reliability of the DTU.
