Embodiment Construction

[0090] (1) System initialization

[0091] Such as figure 1 As shown, the CA certification center issues digital certificates to the background server and W readers, and the background server fills the label with the key and sets the label time stamp T last It is the current time of the background server, and correspondingly records the corresponding relationship between the unique identification code ID of the tag and the key of the tag in the background database, and then attaches the tag to the identification object.

[0092] (2) System operation process

[0093] Such as figure 2 shown. First, the background server determines a certain reader R i for the search task reader; then, with the R i Use the TLS / SSL protocol for two-way authentication, so that both parties can confirm the legitimacy of the identity of the other party; after that, the background server sends its label to search the access list Here the key information k of the label s with its tag ID r i Th...

Abstract

The invention relates to a lightweight no-service type RFID (radio frequency identification) safe search protocol. The protocol uses multiple tag collision for protecting the privacy of a target tag; a loose timestamp and a one-way Hash function are used, so that the safety problem possibly occurring to a data link between an RFID reader and the tag is effectively solved; and under the condition that no background server exists, the HASH function which can be realized through a passive tag is adopted, so that safe search and bidirectional authentication to the tag are guaranteed, and excellent characteristics of fast search and safety certificate are realized. Common active and passive attacks in a wireless link can be effectively resisted. The lightweight no-service type RFID safe search protocol is ingenious in structure and wide in application environment, and has a high safety level and privacy level.

Description

technical field [0001] The invention relates to a lightweight non-service RFID security search method, which belongs to the technical field of RFID communication security. Background technique [0002] RFID technology has many advantages such as non-contact reading, readable and writable, batch reading, and applicable to harsh environments. Therefore, RFID technology has received more and more attention in the fields of identification, sensor positioning, and logistics tracking, and is widely used in various industries such as logistics, aviation, transportation, and pet management. However, large-scale promotion has made security and privacy issues increasingly prominent, which has become a key factor restricting its development. Using wireless channels for non-contact reading not only brings convenience, but also provides good attack conditions for attackers. The use of passive attacks can lead to the leakage of company data and customers' personal privacy, malicious tra...
