Abstract: Various implementations described herein are directed to an apparatus having a processor and memory having instructions stored thereon that, when executed by the processor, cause the processor to identify conductive paths in a physical layout of an integrated circuit having nodal features that define a connective structure of the integrated circuit. The instructions may cause the processor to traverse the conductive paths to detect valid metals and redundant metals. The valid metals may refer to valid conductive paths between the nodal features that conjoin the nodal features. The redundant metals may refer to unused conductive paths that provide disjointed paths from the nodal features. The instructions may cause the processor to indicate the valid metals as marked with a first indicator and to indicate the redundant metals as unmarked with a second indicator that is different than the first indicator.

Abstract: This application discloses a remote attestation method and an apparatus. The method specifically includes: A first network device receives encrypted information and first measurement information of a second network device through the second network device, where the encrypted information is information obtained by encrypting second measurement information of a third network device; the first network device determines, based on the first measurement information, that the second network device is system-trusted; and the first network device decrypts the encrypted information to obtain the second measurement information.

Abstract: This application discloses a remote attestation mode negotiation method and apparatus. Before remote attestation is performed, automatic negotiation is performed between a to-be-verified network device and a server, so that the to-be-verified network device and the server can determine, through negotiation from remote attestation modes supported by both the to-be-verified network device and the server, a remote attestation mode used to subsequently perform remote attestation between the network device and the server, and there is no need to manually statically configure a remote attestation mode for the network device and the server, thereby greatly reducing labor costs of determining the remote attestation mode. In addition, when there are a large quantity of devices, the automatic remote attestation mode negotiation method also helps configure a remote attestation mode more flexibly.

Abstract: In a data collection method for a remote attestation process, a remote attestation server delivers a subscription configuration to a network device, where the subscription configuration for subscribing to information related to remote attestation performed by the network device. The remote attestation server receives the subscription information returned by the network device based on the subscription configuration.

Abstract: The present invention relates to a Fischer-Tropsch synthesis process and system. The process comprises: a) introducing a feedstock gas containing CO and H2 into a first stage Fischer-Tropsch synthesis reactor to carry out a Fischer-Tropsch synthesis reaction; b) separating products of the first stage Fischer-Tropsch synthesis reaction, to separate water from the unconverted tail gas and to obtain hydrocarbon products and the unconverted tail gas; c) introducing the unconverted tail gas obtained in Step b) into a second stage Fischer-Tropsch synthesis reactor to carry out a Fischer-Tropsch synthesis reaction; d) separating products of the second stage Fischer-Tropsch synthesis reaction, to separate water from the unconverted tail gas, with a portion of the unconverted tail gas of the second stage Fischer-Tropsch synthesis reaction being returned to the second stage Fischer-Tropsch synthesis reactor for recycle reactions. The process and system are suitable for large-scale industrialized production.

Abstract: Disclosed is a process for reducing sulfur and olefin contents in gasoline, comprising contacting gasoline feedstock and hydrogen with a hydrorefining catalyst and an paraffin-modification catalyst. The effluent of the process is separated to obtain a hydrotreated gasoline fraction free of mercaptan and having a low content of sulfur, e.g. less than 200 ppm, a low content of olefins, e.g. less than 20% by volume, and little octane loss. The hydrotreated gasoline fraction can be used as blending component of a final gasoline product.
