20220294617 | System and Method for Proactively Buffering Quantum Key Distribution (QKD) Key Material - A system and method are provided for proactively buffering quantum key distribution (QKD) key material. The method includes monitoring key generation rates and surpluses at QKD devices at each node of a QKD link in a QKD network, retrieving surplus key material from the QKD devices at one or both nodes of the QKD link, and buffering the surplus key material in a local storage at one or both nodes in the QKD link. The surplus key material can be used to offset overhead introduced in securely relaying keys between non-adjacent demand pairs in the QKD network. The surplus key material can also be used to offset future transient decreases in key generation rates. | 2022-09-15 |

20220294622 | METHODS AND SYSTEMS TO ESTABLISH TRUSTED PEER-TO-PEER COMMUNICATIONS BETWEEN NODES IN A BLOCKCHAIN NETWORK - Methods and devices for two nodes to authenticate each other as credentialed by a group of autonomous specialized nodes, without involving the group or involving a centralized certificate manager or authenticator. The method may involve a first node and a second node using bilinear pairing operations involving their respective identifiers and secret points to derive the same session key. Provided the secret points and identifiers were obtained from the group using the group private key, the bilinear pairing operation leads to generation of the same session key at each of the two nodes, thereby authenticating their respective credentials and enabling trusted communications between the two nodes. | 2022-09-15 |

The method for generating a key includes: sending, by an enrollee, a first request message to a configurator, the first request message comprising a first identifier, and the first identifier used to instruct the configurator to perform a network reconfiguration operation; receiving, by the enrollee, a first message sent by the configurator and including first key information; generating, by the enrollee, a session key according to the first key information; sending, by the enrollee, a second message to the configurator, the second message comprising second key information, thus allowing the configurator to generate the session key according to the second key information. In a process of an enrollee and a configurator performing provisioning for the first time, key information of each other is exchanged to generate a session key required for subsequent network reconfiguration performed on the enrollee, so that when the network reconfiguration is performed on the enrollee, it is unnecessary to perform an authentication process again, thereby improving the network configuration efficiency. | 2022-09-15 |

According to the encryption method of the embodiment of the present disclosure, the terminal apparatus can be used to determine the encryption information of the storage apparatus, and to set a password, so that the storage apparatus encrypts the data stored in its private partition based on the password. The encryption is executed by the storage apparatus without occupying the processing resources of the terminal apparatus. Besides, the shared partition is not required to be encrypted. Therefore, when accessing the data stored in the shared partition, there is no need to enter a password, which improves the convenience of operation. | 2022-09-15 |
