Abstract: A timestamp generation method and apparatus, and an electronic device and a storage medium, which are used for solving the technical problem of recorded information being easily leaked because a trusted third party is usually needed as a timestamp authority for recording in a traditional trusted timestamp generation method. In the present invention, the method comprises: acquiring a file record; calculating a hash value of the file record; sending the hash value to a random issuer, and receiving a signature result returned by the random issuer, wherein the signature result is generated after the random issuer signs the hash value and a receiving time, and the receiving time is the time when the random issuer receives the hash value; and storing the signature result in a blockchain as a timestamp of the file record.

Abstract: A trusted anonymous voting method includes: performing a hash operation on original voting content to obtain a hash output including a commitment value cvi; blinding the commitment value cvi based on information of other voters to obtain commitment value tuples {tilde over (c)} and {tilde over (x)}; signing the commitment value tuple {tilde over (c)} by using an ESDSA to obtain a signature tuple {tilde over (s)}; and establishing a vote tuple ({tilde over (c)}, {tilde over (s)}, {tilde over (d)}) based on the commitment value tuple {tilde over (c)}, the signature tuple {tilde over (s)} and a signature tuple {acute over (d)} of other voters, and uploading the vote tuple (?, ?, {acute over (d)}) and the commitment value tuple {tilde over (x)} to the blockchain, where signature tuple {tilde over (d)} is generated in a case that other voters verify the signature tuple {tilde over (s)} and the signature tuple {tilde over (s)} passes the verification, and the commitment value tuple {tilde over (x)} is used to decry

Abstract: Embodiments of an Antenna and Filter Unit (AFU) for an Advanced Antenna System (AAS) are disclosed herein. In one embodiment, an AFU for an AAS comprises a first unit and a second unit. The first unit comprises a 1:N power splitter comprising an input coupled, directly or indirectly, to an antenna port of the AFU and N outputs, where N?2. The first unit also comprises N first board-to-board type connectors electrically connected to the N outputs of the 1:N power splitter, respectively. The second unit comprises N second board-to-board type connectors configured to be electrically coupled to the N first board-to-board type connectors, respectively, and N antenna elements coupled, directly or indirectly, to the N second board-to-board connectors, respectively. By positioning the 1:N power splitter prior to the N first and N second board-to-board type connectors, input power at each of the board-to-board type connectors is reduced, which thereby reduces Passive Intermodulation.
