Abstract: The present application discloses a method for processing sequence data, a storage device, and a storage system. The method is applied to a storage device, which processes data in the form of sequence data streams, and includes: the storage device receiving sequence data sent by the host terminal; the storage device storing the sequence data in the form of sequence data streams and setting up corresponding sequence data indexes; the storage device receiving data operation commands for the sequence data from the host terminal, and processing the corresponding sequence data based on the sequence data indexes. Through this method, it is possible to significantly simplify the software stack on the host terminal and reduce the storage access load on the host terminal's processor and memory.

Abstract: The present invention provides a method and a device for generating an HD wallet name card and a method and a device for generating an HD wallet trusted address. The method for generating the HD wallet name card comprises: first signature information is obtained by digitally signing first user information with a first private key; second signature information is obtained by digitally signing second user information with a first trusted private key; and the first user information, the second user information, the first signature information and the second signature information are integrated to generate the HD wallet name card. The present invention is advantageous in that the wallet information is digitally signed with the preset first trusted private key and the first private key, thus preventing the HD wallet name card from being forged, intercepted, and modified by a third party so as to ensure the security of transaction.

Abstract: The present invention provides a method for generating a seed and a device thereof. The method includes: obtaining an algorithm key and generating a target seed algorithm sequence by the algorithm key and a seed algorithm group; obtaining inputted seed generation data; and finally inputting the seed generation data into the target seed algorithm sequence to generate a seed corresponding to the seed generation data. A target seed algorithm is generated by a seed selection algorithm, the algorithm key, calculation rounds and a target seed algorithm group are inputted into the seed selection algorithm, and the target seed algorithm adopted in the current calculation round is outputted. The target seed algorithm for all calculation rounds is combined into a target seed algorithm sequence. This invention increases the computational complexity of the third party through the seed generation data to collide the seed, thereby improving the security of the seed.
