Problems solved by technology

[0003] But the way of RFID recording has fatal security risks
For example, when an attacker maliciously copies a card, the card reader directly modifies the information stored in the card without verifying whether the card is legal, which will cause damage to the RFID
Similarly, when an attacker forges a card reader, the card does not authenticate the legitimacy of the card reader and directly allows the card reader to read the data information stored inside it, which will lead to the leakage of some important data information inside the card, giving Huge damage to users and systems
Since the above situation will damage the RFID system and user information, it is necessary to make further improvements to the current RFID system to improve the security of the RFID system

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] The technical scheme of the invention includes a card authentication initialization process, a card reader authentication initialization process, a card authentication process and a card reader authentication process. The system initialization process is as follows figure 1 As shown, it mainly includes card authentication initialization and card reader authentication initialization. The two-way authentication process of the system is as follows: figure 2 As shown, it mainly includes card authentication and card reader authentication.

[0040] (1) System initialization

[0041] When a new card needs to be generated in the system, the card needs to be initialized, including card data area initialization, card authentication initialization and card reader authentication initialization.

Abstract

The invention discloses a bidirectional authentication method for a card reader and a label in an RFID (radio frequency identification device) system. Before the card reader reads card data, the card reader needs to authenticate validity of a card; similarly, the card authenticates the validity of the card reader; only when the both parties are valid, the card reader can read the card information, and the card permits the card reader to read the information thereof. By virtue of the method, the security of the RFID system can be effectively ensured.

Description

technical field [0001] The present invention relates to a method for two-way authentication of a card before a card reader reads the card, more particularly, refers to a method based on encrypting and authenticating the ID of the card, and improves the efficiency of the system through the two-way authentication of the card. safety. Background technique [0002] With the advancement of MEMS and digital electronic technology, RFID (Radio Frequency Identification) technology was born. Using RFID technology, the radio frequency module is controlled by a single-chip microcomputer, and the antenna is used to emit a resonant magnetic field suitable for radio frequency tags, which can effectively realize data communication with radio frequency tags, and complete the identification of radio frequency tags and the acquisition and setting of data in the card. At present, RFID technology has been widely used in manufacturing and assembly, air baggage handling, mail / express package hand...
