Problems solved by technology

If the operation password of the reader to operate the electronic tag is leaked, then the attacker can take out the same type of reader to change the data of the electronic tag according to this password. Obviously, such security needs to be improved.

Embodiment Construction

[0039] Such as figure 2 As shown, in a preferred embodiment of the present invention, an efficient and safe RFID system includes an electronic tag unit 1 , a reader unit 2 and an RFID application software unit 3 . The electronic tag unit 1 includes a public storage module 10, a data transceiver module 11 and a private storage module 12; the reader unit 2 includes a tag operation module 20, a host interface module 21, a first encryption and decryption module 22 and a first random number acquisition module 23 The RFID application software unit 3 includes a reader-writer interface module 30, a user tag ciphertext storage module 31, a second encryption and decryption module 32 and a second random number module 33.

[0040] The public storage module 10 and the private storage module 12 are respectively connected to the data transceiving module 11 . Public label ciphertext is stored on the public storage module 10, and the public label ciphertext is used for the legality authentic...

Abstract

The invention provides an efficient and safe RFID (radio frequency identification device) receiving and transmitting method and system. The method is applied to RFID application software, a reader-writer and an electronic tag. The method comprises the following steps that an electronic tag sends a public tag ciphertext to a reader-writer; the reader-writer sends the received public tag ciphertext to RFID application software; after receiving the public tag ciphertext, the RFID application software queries whether the same tag ciphertext is stored in advance, if not, no operation is carried out on the electronic tag any more; otherwise, the RFID application software sends a tag authentication success result to the reader-writer; after receiving the tag authentication success result, the reader-writer decrypts the public tag ciphertext to obtain an electronic tag operation password. The operation password is encrypted into the public tag ciphertext, and the content stored in the RFID application software is also a ciphertext but not a real operation password, so that the operation password is prevented from being disclosed and the safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of RFID communication, in particular to an efficient and safe RFID transceiving method and system thereof. Background technique [0002] The existing RFID system consists of electronic tags, readers and RFID application software (such as figure 1 shown). At present, in terms of the security of RFID systems at home and abroad, the reader uses the operation password when operating the electronic tag; the data communication between the reader and the RFID application software adopts an encryption method. This security mechanism is only established between the reader-writer and the electronic tag, or between the reader-writer and the RFID application software, and does not closely link the three together. Ordinary personnel who operate electronic tags can see the operation password of the electronic tag from the interface, and the possibility of password leakage is very high. If the operation password of the ...
