20220158834 | METHOD AND DEVICE EMPLOYING SMART CONTRACT TO REALIZE IDENTITY-BASED KEY MANAGEMENT - Provided are a method and device employing a smart contract to realize identity-based key management. The method comprises: running a smart contract, and executing a key management process, wherein the key management process comprises: when a key of a target user requires an update and the target user is not a supervised user, generating a master public key and a master private key pertaining to the target user; acquiring, from a blockchain, identity information of the target user; generating a first target private key according to the master public key and the master private key pertaining to the target user and the identity information of the target user; and replacing a current private key of the target user with the first target private key. | 2022-05-19 |
20220158835 | ZERO-KNOWLEDGE AUTHENTICATION BASED ON DEVICE INFORMATION - An electronic device generates a first key pair associated with the electronic device. A first secret key of the first key pair is generated based on device properties including identification information of the electronic device. The electronic device transmits a communication request to a verifier device. The electronic device generates zero-knowledge information which is based on the generated first secret key. A first public key of the first key pair is stored in the verifier device. The electronic device transmits the zero-knowledge information to the verifier device for a verification of the transmitted communication request. The verification of the communication request is based on the first public key. The electronic device receives verification information from the verifier device based on the transmitted zero-knowledge information and a successful verification of the verification of the transmitted communication request. The electronic device communicates with the verifier device based on the received verification information. | 2022-05-19 |
20220158836 | Fork Processing Method And Blockchain Node - The disclosure provides example block generation methods. One example method includes that when a first blockchain node is a leader, packing, by the first blockchain node, a leader-elected transaction in a transaction pool into a first block, where the leader-elected transaction records a leader proof of the first blockchain node. The leader proof records a voting state in which each of the plurality of second blockchain nodes votes on the first blockchain node, and the voting state indicates whether a vote is a positive vote or a negative vote. Sends the first block to the plurality of second blockchain nodes, so that the first blockchain node and/or the second blockchain nodes perform fork processing based on the leader proof. | 2022-05-19 |
20220158837 | METHOD FOR SEAMLESSLY RECOVERING A SINGLE SIGN-ON PASSWORD IN WI-FI MULTI-ACCESS POINT DEVICE NETWORK - A client device for use with a gateway device (or a Wi-Fi APD) with a key stored therein and an external server where an original singe sign on (SSO) password is stored. The client device transmits a one time password (OTP) request to the external server, obtains the OTP from the external server, transmits the OTP to the external server to authenticate the client device, transmits an encrypted SSO password request to the external server, onboards the gateway device using a temporary password, receives the encrypted SSO password from the external server, obtains the key from the gateway device, decrypts the encrypted SSO password using the key to obtain the SSO password, and changes the temporary password of the gateway device to the original SSO password. | 2022-05-19 |

20220158839 | METHODS AND DEVICES FOR SECURE APPLICATION AUTHENTICATION USING A ONE-WAY ENCRYPTED AUTHENTICATION TOKEN - A client application component of a device may provide a request to an authentication component of the device for an authentication token, in order to authenticate an application with a server. The authentication component may generate the authentication token to be one-way encrypted, based on a server token and a data string associated with security information corresponding to the application, and device information that identifies the device. The client application component may receive the authentication token from the authentication component. The client application component may generate, based on the authentication token, a client token and transmit the client token to the server to authenticate the client application. | 2022-05-19 |
20220158840 | METHODS AND SYSTEMS FOR EXCHANGING CONFIDENTIAL INFORMATION VIA A BLOCKCHAIN - A method for supporting verification of information pertaining to a target includes detecting an indication that a request transaction has been received by a smart contract deployed on a blockchain, the request transaction indicating a request to verify information pertaining to the target. The method also includes retrieving the request based on the request transaction. Further, the method includes: generating a reply transaction indicating at least (i) a reply to the request, and (ii) an address, on the blockchain, of an originator of the request; and providing the reply transaction to the smart contract. | 2022-05-19 |
20220158841 | METHODS AND DEVICES FOR PROVING KNOWLEDGE OF A DATA ITEM BY A USER OF A BLOCKCHAIN - A method is described for proving knowledge of a first data item by a user registered to a blockchain, the first data item belonging to the user, the method being implemented by a trusted entity registered on the blockchain. The method includes obtaining the first data item outside the blockchain, generating a second data item from the first data item, outside the blockchain, the second data item to the user, and publishing the second data item in the blockchain after the second data item has been published in the blockchain by a terminal of the user. | 2022-05-19 |
