A data processing method based on secure multi-party computation, an electronic device and a storage medium are disclosed. The data processing method requires firstly obtaining original confidential data and shared key information from a data holding terminal; performing a first encrypting process to the original confidential data based on the shared key information to generate original encrypted data; and then sending the original encrypted data to a node server. Further, the node server obtains a plurality of pieces of the original encrypted data, and performs a service parsing process to generate encrypted result data, and sends the encrypted result data to a data reconstruction terminal. Furthermore, the data reconstruction terminal obtains the encrypted result data and the shared key information, and performs a reconstructing process to the encrypted result data according to the encrypted result data and the shared key information to obtain service result data.

A method for improving energy efficiency performance of a reader is disclosed in the present document. The method includes: initializing and adjusting operation parameters, and acquiring the current number of frame timeslots; updating a frame timeslot status, and determining that a power level is not required to be increased according to the updated frame timeslot status; and estimating the number of labels according to the current number of frame timeslots, and acquiring an optimum Q value according to the number of labels. A device for improving energy efficiency performance of a reader is also disclosed in the present document. With the method and device of the present document, throughput of a Radio Frequency Identification (RFID) system is maximized, thereby reducing energy consumption of the system and extending usage time of the system; and while the energy consumption is reduced, a rate at which the reader reads the labels is guaranteed.

The present disclosure discloses a method for dynamic authentication between a reader and a tag, and an implementing device therefor, to solve the technical problem of necessity of dependence of a traditional authentication method on a real-time, online, reliable and secure connection with a background database, as well as lack of ways for highly autonomous authentication of a tag by a reader. In the present disclosure, only a legitimate reader can obtain corresponding tag authentication information from an authentication database and authenticate or update a corresponding tag status; only a legitimate tag can be processed by the legitimate reader; during the authentication, a dynamic updating mechanism is used for a tag ID which ensures forward security; the reader stores tag information using a hash table and thus increases an authentication speed; data synchronization is achieved cleverly by ways of a counting value. The use of a random number guarantees that a different data packet is used for every authentication, thus hiding tag position information effectively and offering excellent security.

Method for dynamic authentication between reader and tag, and device therefor

A reporting method for a network state includes: an intermediate node receiving a data packet; the intermediate node marking the data packet according to the current network state; and the intermediate node forwarding the marked data packet. A detecting method for a network state includes: a sink node receiving a data packet; the sink node parsing the data packet to obtain the marking information about the network state; and the sink node determining the network state according to the marking information. A reporting device corresponding to the reporting method, a detecting device corresponding to the detecting method, and a detecting system comprising the reporting device and the detecting method are also provided.
