摘要： 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.

摘要： 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 means 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 means 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.
