Intrusion detection method of radio frequency identification system based on ontology

Abstract

The invention provides an intrusion detection method of a radio frequency identification system based on ontology. Based on an ontology semantic definition rule, a radio frequency identification intrusion detection system and a method of a two-grade defense system are established with the combination of the tracking of radio frequency identification tags and the positioning technology. To accomplish the design of the method, the invention specifically brings forward an ontology-based inference engine to provide the inference capability of tag clone for the radio frequency identification intrusion detection system. By employing the tracking of the radio frequency identification tags and the positioning technology, a model with the combination of semantic position and physical position is designed to fight against tag clone. An advanced engine based on the ontology semantic rule can provide an advanced automatic inference capability for a radio frequency identification misuse detection system (RIDS). When a tag object is duplicated, or a clone attack occurs, the engine can accurately provide the formalized model for intrusion detection.

Description

technical field [0001] Aiming at the increasingly serious problem of radio frequency identification tag cloning attacks in radio frequency identification systems, the present invention designs a radio frequency identification system tag cloning attack intrusion detection system based on semantic definition rules of ontology, and designs an intrusion detection system that can track cloned tags and The positioning method belongs to the defined field of network security. Background technique [0002] With the development of computer and Internet of Things technology, the radio frequency identification system has been continuously developed, and different application types are constantly increasing. In many application scenarios, the most challenging security issue is tag cloning. In order to deal with this threat, researchers mainly use three countermeasures: tag encryption, identity authentication and access control. [0003] The implementation difficulty of these several cou...

Problems solved by technology

However, those large companies with large-scale end users encourage developers to reduce the cost of tags. Therefore, due to the limited power of low-cost tags, as well as their limited storage and processing resource capabilities, they want to use the enhanced tag encryption algorithm as a countermeasure. To deal with label cloning is difficult to achieve

In addition, in order to provide enough power to the encryption components, the tag needs to be read within a shorter distance, which will greatly reduce the read rate of the reader

Although there are many improved schemes for the above-mentioned schemes, there are still a large number of studies pointing out that this scheme cannot completely protect tags from cloning attacks.

[0004] First of all, this solution is inherently insecure. In an RFID system, the limited functionality of the tag makes it the weakest link in the entire system chain: attackers can easily break through using simple equipment and techniques. Radio Frequency Identification Security Protection

Furthermore, it is not possible to develop a truly secure RFID tag that addresses all known vulnerabilities without increasing the cost of the tag

Second, existing solutions mainly focus on preventing tag cloning without addressing proactive prevention of tag cloning
