Problems solved by technology

Since the existing wireless communication between the reader and the tag is carried out in plain text in most cases, since no encryption mechanism is used, the attacker can obtain and use the information on the RFID tag

Embodiment Construction

[0037] Further illustrate the present invention below in conjunction with accompanying drawing. Refer to attached image 3 :

[0038] What the present invention adopted is based on the two-way authentication of AES encryption algorithm and message encryption mechanism, and its working steps are as follows:

[0039] Step 1, the initial stage. The data to be written into the tag by the reader, such as each patient's unique number, name, gender, etc., is encrypted with the AES encryption algorithm and then written into the tag, so that no user information in plain text is stored in the tag. This prevents attackers from obtaining user information by attacking tags;

[0040] Step 2, authentication phase. The reader-writer and the electronic tag need two-way authentication to verify each other's legitimacy. The two-way authentication flow chart is as follows: figure 1 shown. Among them, FK represents the inherent key of the electronic tag and the reader, which is fixedly allo...

Abstract

Disclosed is a method for encrypting a wireless sensor network in an intelligent medical system. Firstly, the operation of writing information is carried out in an electronic tag, then sensitive information in an RFID tag is encrypted through a bidirectional authentication protocol of an AES encryption algorithm and a message encryption mechanism to improve system security, and an attacker is prevented from eavesdropping messages.

Description

technical field [0001] The invention relates to an encryption method applied to a wireless sensor network of an intelligent medical system. Background technique [0002] With the development of wireless sensor network WSN (Wireless Sensor Network), RFID (Radio Frequency Identification, radio frequency identification technology) and mobile computing technology, hospitals are about to usher in a far-reaching information technology revolution. The hospital will become a new type of efficient operation system centered on the patient, centered on medical processes such as diagnosis, examination, and nursing, and supported by pharmacies, logistics, and administration. Real-time transmission of test results, wireless electronic medical records and other functions are developed in the direction of intelligence, becoming a smart hospital. The development of smart hospitals not only slows down or even solves the increasingly tense doctor-patient conflict technically, but also effecti...
