Title: Method, server, client and system for processing digital currency transaction data
Inventor: CHEN DAI
IPC: H04L9/08
Filed: 2019-02-25
Abstract: A method, a server, a client and a system for processing digital currency transaction data. A private key of a transaction account is divided into different private key components respectively possessed by different secret key service clients corresponding to digital currency transactions, namely different users. Execution of a digital currency transaction requires agreement of the respective secret key service clients on a transfer transaction, and then the private key components stored in the respective secret key service clients are used to perform signature computation to obtain signed data for validation of transfer information. A sum of the private key components stored in the respective secret key service clients is the private key of the transaction account. The signed data is obtained by using the private key of the transaction account to affix a signature, thereby completing a signed transfer associated with the transaction account. Since private key components of a transaction account are separately stored, completion of a transfer transaction requires a signature formed from the private key components stored in multiple secret key service clients, thereby ensuring secure digital currency transactions.

Abstract: Embodiments of the present disclosure relate to bandwidth part switch mechanism. According to embodiments of the present disclosure, in non-ideal backhaul, the terminal device receives a BWP switch request from a network device and transmits information on the BWP switch request to a further network device. If the further network device agrees with the BWP switch, the terminal device switches the BWP. In ideal backhaul, the network device and the further network device negotiates the BWP switch and transmit the BWP switch request to the terminal device if the network devices both agree with the BWP switch. In this way, latency of BWP switch is reduced, thereby saving time.
