Abstract: A method for authenticating a counterparty to a digital transaction includes obtaining, at a mobile terminal from a unverified counterparty, characteristic content associated with the digital transaction to be displayed in a trusted user interface provided by the mobile terminal, sending, by the mobile terminal, data associated with the characteristic content to an authentication server; and obtaining, from the authentication server, a result of an authentication judgment by the authentication server, the authentication judgment based on the data associated with the characteristic content and an item of reference content.

Abstract: A method comprises: providing a weldment and a welded plate to which the weldment is to be welded, an end of the weldment to be welded to the welded plate being provided with a first welding face and a second welding face, the first welding face and the second welding face forming a pointed cone, the first welding face corresponding to a first welding area, and the second welding face corresponding to a second welding area; in the first welding area, welding being performed at the innermost side of the pointed cone to form a first welding pass; in the second welding area, welding being performed at the innermost side of the pointed cone to form a second welding pass, and then welding being performed at the outer side of the second welding pass to form a third welding pass adjacent to the second welding pass.

Abstract: A method includes receiving a challenge from an authentication consumer. The method also includes generating for display a figure associated with an identification, a public certificate, and a private key after receiving the challenge. The figure, the identification, the public certificate, and the private key are stored in a TrustZone (TZ) enriched environment. The method further includes receiving an input identification. The method includes verifying that the input identification matches the identification. The method also includes transmitting the challenge to the authentication consumer in response to verifying that the input identification matches the identification.

Abstract: An apparatus and method for providing a secure payment transaction on a mobile device are provided. The method includes determining, using a computer processor of the mobile device, whether a requested operation is a security sensitive operation, and when the requested operation is determined to be a security sensitive operation, executing the requested operation in a secure environment of the mobile device.

Abstract: An apparatus and method for secure electronic payment are provided. The method includes authenticating a user of an electronic device executing a trusted payment application in a trusted execution environment of the electronic device, receiving credit card data from the user, generating credit card track data based on the received credit card data, and storing the credit card track data.

Abstract: Methods, electronic devices, and systems for exchanging encrypted information. A method for exchanging encrypted information by an electronic device includes generating one or more device certificates and one or more device public private key pairs. The one or more device certificates are signed using a device unique private key that is pre-stored on the electronic device. The method also includes sending the one or more device certificates to a server of a token service provider (TSP). The method further includes receiving one or more TSP certificates from the TSP server. The method includes identifying one or more TSP public keys of the TSP server based on the one or more received TSP certificates. Additionally, the method includes transmitting a message including the information encrypted based on the one or more identified TSP public keys and a signature of the electronic device.

Abstract: A system includes one or more computing devices accessible over a network and managed by a service provider. A hoster user accessing the system over the network, and who is at least partially unaffiliated with the service provider, is permitted to instantiate in accordance with a desired configuration a virtual machine hosted at and realized by hardware resources of the computing devices. The hoster user is further permitted to assign one or more end users unaffiliated with the service provider to the virtual machine in accordance with a desired permission specified by the hoster user. The end users accessing the system over the network, and who are unaffiliated with the service provider, are permitted to access and use the virtual machine in accordance with the desired permission specified by the hoster user.

Abstract: The present invention relates to coal chemical processing, and particularly to a thermal dissolution catalysis method for preparing liquid fuel from lignite. The method comprises steps of: 1) crushing and drying lignite into coal powder; 2) stirring and mixing coal powder, a solvent and a catalyst sufficiently to form coal slurry, wherein there are 30-40% mass of coal powder, 60-70% mass of solvent, and 0.5-1% mass of catalyst relative to coal powder mass; 3) subjecting the coal slurry to thermal dissolution catalysis reaction to obtain thermal dissolution liquefied product, wherein the reaction is carried out for 30-60 minutes at a temperature 390-450° C. under a pressure 5.0-9.0 MPa; 4) separating the thermal dissolution liquefied product into gas, liquid and solid phases; and 5) upgrading the liquid product into liquid fuel. The present invention further discloses a catalyst and a solvent for use in the above method.

Abstract: The present invention discloses a process for hydroconverting a heavy hydrocarbon chargestock, wherein said chargestock oil is first contacted with a highly active homogeneous hydrogenation catalyst to effect the hydrogenation reaction so that macromolecular radicals of the residue (the precursor of coke) form as less as possible, thereby decreasing the output of coke in the hydrocracking of the residue; when the reaction proceeds to a certain extent, a solid powder is added to adsorb the macromolecular radicals of the residue formed during the reaction and lower their reaction activity, thereby preventing them from further condensing to coke and/or depositing due to polymerization. The synergetic action of the two sorts of substances makes it possible to produce substantively no coke or less coke during the hydrogenation of residue in a suspension bed and prolong the operation lifetime of the unit.
