RFID authentication method for elliptic hyperbola-based public key encryption mechanism

Abstract

The invention discloses an RFID authentication method for an elliptic hyperbola-based public key encryption mechanism. According to the method, key distribution is carried out by using an elliptic hyperbola DH theory, a generation system of fresh keys is constructed, communication data between encryption entities of the fresh keys is used for ensuring the randomness and unpredictability of a datastream, and a secure communication channel between a label and a reader is established; communication entities store a public key and private key pair generated by the elliptic hyperbola theory, and identity authentication between the entities is realized in a digital signature mode, so that the effectiveness of the authentication is ensured; and after the security authentication is realized, a session key used for encrypting the data is generated, so that sensitive data interaction between the entities is facilitated. Common security threats such as mutual authentication, anonymity, reliability, forward privacy, location privacy, man-in-the-middle attack, counterfeit attack and the like can be prevented, and a distribution function of the session key is provided, so that the security andprivacy of the channel between the label and the reader are ensured.

Description

technical field [0001] The invention relates to the technical field of RFID, in particular to an RFID authentication method based on an elliptic hyperbola public key encryption mechanism. Background technique [0002] RFID is a non-contact radio frequency identification technology. Its basic principle is to use radio frequency signals and space coupling to realize non-contact information transmission and automatic identification of identified objects. It has the characteristics of large data storage capacity, readable and writable, strong penetrating power, long recognition distance, fast recognition speed, long service life and good environmental applicability. RFID replaces the two-dimensional code technology, and can quickly realize the identification, authentication and real-time communication with the target object without the limitation of line-of-sight. In recent years, with the development of Internet of Things technology, the application of RFID technology has beco...
