Abstract: This disclosure discloses a device management method, system, and apparatus. The method includes: A second device sends an identity file to a first access control node, to indicate the first access control node to store the identity file in a file system, where the identity file includes identity information of a first device and a public key of the second device. The second device receives a first identifier sent by the first access control node. The first identifier is used to read the identity file from the file system. After verification is performed on the second device and information about a device associated with the first device in association information and succeeds, the first access control node sends the identity file to the file system. The association information is stored in a database node and a blockchain.

Abstract: A symmetric key-based generation and distribution system and method for a vehicle access authentication framework is provided, the framework comprising: a first device operated by a car owner, a second device operated by a delegated user, and a third device residing in a vehicle. The first device is configured to: request for an authentication key from the third device, the request for the authentication key comprising an ID of the first device, idO; receive an authentication key KidO from the third device; and generate a delegated authentication key KidU based on authentication key KidO and an ID of the second device in response to receiving a request for delegated authentication key from the second device, the request for delegated authentication key comprising the ID of the second device.

Abstract: A system for controlling access to encrypted vehicular data employs a hierarchical access control method that allows select encrypted vehicular data stored in a cloud server to be accessed by an authorized user in a hierarchical manner whereby the authorized user is then able to decrypt the select encrypted data and all child data associated with the select encrypted data.

Abstract: An information processing method, a terminal device, and a network system include encrypting, by a first terminal, an authorization key based on a public key of a second terminal to obtain an authorization key ciphertext corresponding to the second terminal, and sending, by the first terminal, the authorization key ciphertext to the second terminal such that the second terminal decrypts the authorization key ciphertext based on a private key of the second terminal to obtain the authorization key, and then performs file decryption.

Abstract: An in-vehicle gateway communication method includes receiving a first message from a first in-vehicle device. An in-vehicle gateway identifies identification information in the first message, and matches the identification information with preset identification information stored in the in-vehicle gateway, and only when the matching succeeds, the in-vehicle gateway sends a second message, to indicate, using the second message, a second in-vehicle device to perform a target operation. When the identification information in the first message does not match the preset identification information stored in the gateway, the in-vehicle gateway does not send the second information to control the second in-vehicle device to perform the target operation. Therefore, identification information of a first message is set in an in-vehicle gateway of a vehicle.

Abstract: This invention relates to a symmetric key-based generation and distribution system and method for a vehicle access authentication framework comprising: a first device operated by a car owner, a second device operated by a delegated user, and a third device residing in a vehicle. The first device is configured to: request for an authentication key from the third device, the request for the authentication key comprising an ID of the first device, idO; receive an authentication key KidO from the third device;; and generate a delegated authentication key KidU based on authentication key KidO and an ID of the second device in response to receiving a request for delegated authentication key from the second device, the request for delegated authentication key comprising the ID of the second device.

The system described in this document employs a hierarchical access control method that allows select encrypted vehicular data stored in a cloud server to be accessed by an authorized user in a hierarchical manner whereby the authorized user is then able to decrypt the select encrypted data and all child data associated with the select encrypted data.

Abstract: A system and method for securing Short Message Service (SMS) communications between two communication devices disclosed herein. SMS communications between these two communication devices are secured using a SMS encryption technique that utilizes the communication device's unique address as inputs to encrypt and decrypt the SMS messages.

Abstract: A user identity authenticating method, a terminal, and server are provided. The method includes determining according to a preset first-biological-feature processing instruction set, whether a currently-entered first user biological feature matches a second user biological feature, to obtain a first result, where the first-biological-feature processing instruction set is configured by a server, and the second user biological feature is a biological feature that is registered on the server; determining, whether the first result is correct; and if the first result is correct, sending the first result to the server to determine whether the first user biological feature is authenticated. The method not only enhances security when the server performs user identity authenticating, but also prevents the second user biological feature from being leaked to a non-secure area.

Abstract: A manufacturing method of a packing cushion for electric equipments includes the steps of feeding, heating, closing mold, injection molding, cooling, opening mold and closing bottom. A recess is defined in a bottom of the packing cushion. A sealant is secured on the bottom of the packing cushion for closing the recess and forming a closed chamber that contains air for promoting the absorbing effect of the packing cushion.

Abstract: A package case includes an upper and a lower case, but only a lower case can be used independently, having air cushion effect. The package case can have a thin upper case, the rear and the bottom portion can be completely or half sealed, and then directly placed in a carton tightly. The package case cannot produce gas explosion or vibration even in case of sudden shock by increasing thickness of material or forming holes when completely or half sealed. Further the package case has various projections, tabs, recesses for space for air flow in case of shock, and the bottom is also formed with various structure to contact or suspend an object to be packed. The contact places are strengthened with reinforcing means in conjunction with various foldable recesses to increase cushion effect for protecting the object packed from damaged.

Abstract: The package case for electric appliances and computers consists of an upper case and a lower case made of a tough thin plastic plate formed to have four sides and a bottom, an hollow interior defined by the four sides and the bottom and having a shape to correspond to the shape of a product to be packaged. Each of the four sides has a sloped outer and inner wall, and a plurality of curved recesses formed in the sloped outer and the inner wall and in the top of each side. The hollow package case placed in a carton may have excellent shock-absorbing function to protect a product packaged therein from damage or hurt caused by shocks or lowering movement in transporting. It is of low cost, handy to handle, reducing pollution to the environment, and having enough shock-absorbing ability for protecting electric appliances and computers.
