Abstract: A method of labeling video to provide authentication acquires an instruction to apply timestamp labeling. Each recorded video is labeled with a timestamp based on the instruction. The first mark information is generated based on a content of each recorded video as a hash value and is uploaded into a blockchain. Second mark information is generated based on a content of at least one video under investigation. By comparing the first mark information and the second mark information, a video under investigation is found to be undistorted and authentic when the first mark information is the same as the second mark information. The video under investigation is found to be non-authentic when the first mark information is different from the second mark information. A terminal device and a computer readable storage medium applying the method are also disclosed.

Abstract: Low power devices are able to utilize encryption in communication. Low power devices typically cannot send/receive large amounts of data since sending/receiving more data uses more power. Implementing a key exchange with a small encrypted payload enables secure communication between the devices. A one-way data stream is implemented. The one-way data stream is able to be encrypted. The dynamic key exchange is able to be used for a moving target.

Abstract: A wireless network access method, apparatus, device, and system are provided.

Abstract: Methods and systems disclosed herein recite the use of linking cryptography-based digital repositories in order to perform blockchain operations in decentralized applications. For example, the system may link a first cryptography-based, storage application (e.g., a first digital wallet) with a second first cryptography-based, storage application (e.g., a second digital wallet). The first cryptography-based, storage application may correspond to a first private key, and wherein the first private key is stored on a first user device. The second cryptography-based, storage application corresponds to a first partial private key and a second partial private key, wherein the first partial private key is stored on a first remote device, and wherein the second partial private key is stored on the first user device.

Abstract: A method is disclosed. The method includes receiving a broadcast signal from a beacon device, the broadcast signal encoding a first credential associated with a first entity. In response to receipt of the broadcast signal, the mobile communication device transmits the received first credential to an authentication system. The authentication system determines if the first entity associated with the broadcast signal is authentic and generates a confirmation message confirming the authenticity of the first entity. The mobile communication device then receives the confirmation message indicating that the first entity is authentic. The mobile communication thereafter receives and transmits a second credential for the mobile communication device to the beacon device, which transmits the second credential to the authentication system. The authentication system then confirms the authenticity of the mobile communication device.

Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Methods and systems are disclosed herein for secure communication between computing devices. A mobile device may communicate with an untrusted device to cause the untrusted device to send information (e.g., encrypted information that the untrusted device is unable to decrypt) to a server using an Internet connection of the untrusted device. The mobile device may have limited or no access to the Internet. To prevent potential security risks associated with using a public or untrusted device, the mobile device may encrypt information stored on the mobile device (e.g., stored in a mobile application associated with the server), send it to the untrusted device (e.g., by displaying a QR code to a camera of the untrusted device), and the untrusted device may send the information to the server via a network connection of the untrusted device.
