Embodiment Construction

[0048] In a wireless radio frequency device equipped with a PUF unit, the response exists when the PUF unit is powered on, and disappears when the power is turned off. Therefore, using the PUF unit for authentication can prevent physical attacks such as probes and electronic scanning. In addition, since each PUF unit will inevitably produce many individual differences during its manufacturing process, the physical difference comes from uncontrollable factors in the manufacturing process, so no matter how the PUF unit is designed, the difference between the PUF unit and the PUF unit There will always be some slight differences between them. Even under the condition that the design, packaging and manufacturing process are completely consistent, it is impossible to replicate two identical PUF units, so the PUF unit is naturally unique and unclonable.

[0049] At present, in the process of mutual authentication with the authentication server, the radio frequency device and the auth...

Abstract

The invention discloses a radio frequency device, an authentication server and an authentication method. The radio frequency device comprises a first authentication unit. The first authentication unit comprises a PUF sub unit, an encoder and a second processing sub unit, wherein the PUF sub unit is suitable for processing a first challenge when the first challenge is acquired and outputting corresponding real response data; the encoder is suitable for carrying out encoding and processing on the real response data, acquiring corresponding auxiliary data and transmitting the auxiliary data to the authentication server; and the second processing sub unit is suitable for processing the real response data, acquiring corresponding first processing data and transmitting the data to the authentication server. When the above radio frequency device is applied, the safety during the authentication process between the radio frequency device and the authentication server can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless radio frequency device, an authentication server and an authentication method. 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 attracted widespread attention in recent years. There are also more and more RFID-based wireless radio frequency devices, such as smart cards, mobile terminals, microprocessors, computers, routers, set-top boxes, and so on. [0003] In practical applications, cloning, counterfeiting attacks, replay attacks, malicious monitoring, malicious interception, and asynchronous attacks are the main attack methods on wireless radio frequency devices. In order to deal with the above-mentioned attacks, before using the radio frequen...
