A radio frequency identification security authentication method and system

Abstract

The invention discloses a radio frequency identification security authentication method. The method comprises the following steps: initializing parameters of a tag, a reader and a server; Wherein authentication is started after parameter initialization is completed, and the method further comprises the steps that the reader sends an authentication request message to the tag; The tag generates a tag authentication signal after receiving the request message; And when the tag judges that the reader is a legal reader, the authentication is completed. The method has the advantages that security threats such as counterfeit attacks, replay attacks, tracking attacks and denial of service can be prevented, it can be guaranteed that strong forward privacy is not leaked under the enemy enhancement capacity, in addition, a public key encryption mechanism is adopted, the difficulty of secret key storage and management of the system is lowered, and scale expansion of the radio frequency identification system is facilitated.

Description

technical field [0001] The present invention relates to the technical field of security authentication, in particular to a radio frequency identification security authentication method based on quadratic remainder law mixed public key encryption and symmetric encryption mechanism. Background technique [0002] In recent years, as a key technology of the sensing layer of the Internet of Things, radio frequency identification has been widely used in public transportation, automatic toll stations, and social security fields due to its advantages of non-contact, readable and writable, and fast identification. In today's society, various forms of performances and public activities such as exhibitions, performances, and sports events are becoming more and more frequent. Traditional manual ticket cutting and checking are inefficient, easy to be damaged, and easy to forge. Applying radio frequency identification technology to tickets can ensure the integration of ticket information ...

Problems solved by technology

However, the synchronous update of the secret key in this strategy is the prerequisite for the reliability of the authentication protocol. The attacker can intercept or tamper with the messages generated by the entity interaction in the wireless link to destroy the synchronization of the secret key update and cause a security problem of denial of service.

In addition, the storage and management of the secret key of the general symmetric encryption mechanism limits the scalability of the radio frequency identification system, and some protocols consider using the elliptic hyperbola to construct the public key encryption mechanism to design the radio frequency identification authentication protocol. However, the elliptic hyperbola is a A complex encryption primitive, its storage and calculation require a lot of resources, which does not meet the low-cost requirements of electronic bills
