Embodiment

[0038] Such as figure 1 As shown, in the method for searching for radio frequency tags efficiently and securely in the present invention, in the initialization stage, the back-end database and tags both have a pseudo-random number generator (denoted as GPRNG) based on the stream cipher algorithm Grain, and the bit derivation function F outputs its The left half of the input, the bit derivation function G outputs the right half of its input, and the three parameters shared between the back-end database and the tag are set as follows: (1) Key k: random uniform characters with a bit length of 96 bits String, (2) pointer value c: an integer with a bit length of 32, and the initial value is 1. (3) Index information I: indicates the index information shared between the back-end database and the tag, and its initial value is the left half of GPRNG(k,1). In each search process, secure transmission and exchange of information between the back-end database, readers and tags. Through th...

Abstract

The invention discloses a high efficiency safety radio frequency label searching method, and relates to the radio frequency identification communication safety technical field; the method comprises the following steps: a rear database forwards index information Is to a reader; the reader broadcasts the Is to all labels in a magnetic field scope; each label receives information, compares self-stored index information I with received Is, thus determining whether the label is the target label or not; the rear database receives confirm information f forwarded by the reader, uses self secret key k and a pointer value c to calculate and compare with f, thus determining whether the searching has succeeded or not. The method uses a pseudorandom number generator to safely calculate labels with low cost, uses the pointer value to synchronize a server with labels, and uses an index information updating method to protect label privacy and authentication; in the whole process, the rear database and labels only need to have the pseudorandom number generator capability, so the searching method is efficient and safe.

Description

Technical field [0001] The present invention relates to the technical field of radio frequency identification communication safety, in particular to an efficient and safe method for searching radio frequency tags. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology that uses radio frequency communication to identify specific target objects. Because RFID technology has the advantages of small size, good durability, strong anti-pollution ability, large memory capacity, easy operation, suitable for harsh environments and non-contact automatic identification, etc., it is widely used in various fields of life and production. At present, the security authentication protocol for RFID technology has been extensively studied, and the RFID tag search method, as an extension of the RFID tag authentication protocol, is an emerging protocol in the RFID field and has very high research value. It requires the reader to quickl...
