Radio frequency device, server and radio frequency communication system

Abstract

The invention discloses a radio frequency device, a server and a radio frequency communication system. The radio frequency device comprises a first key generation unit and a first data processing unit, wherein the first key generation unit is suitable for using real response data of PUF to generate a first key; and the first data processing unit is suitable for using the first key to decrypt the data transmitted by the server or encrypt data to be transmitted to the server. When the above scheme is applied, the communication safety between the radio frequency device and the server can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a wireless radio frequency device, a server and a wireless radio frequency communication system. Background technique [0002] The Internet of Things is called the third wave of the world's information industry after computers and the Internet. Radio Frequency Identification (RFID) technology, as a key technology for building the Internet of Things, has received extensive attention in recent years. There are also more and more radio frequency devices based on RFID, such as smart cards, mobile terminals, microprocessors, computers, routers, set-top boxes and so on. [0003] In practical applications, in order to ensure communication security, the data interaction between the radio frequency device and the server usually needs to be encrypted before being sent to the other party, and the received data needs to be decrypted before the information carried by t...

AI Technical Summary

Problems solved by technology

Once the attacker obtains the key, the communication security between the radio frequency device and the server cannot be effectively guaranteed, and the user's requirements for communication security cannot be met.
