NFC relay attack judgment and safety authentication system and method based on spatio-temporal evolution

Abstract

The invention discloses an NFC (Near Field Communication) relay attack judgment and safety authentication system and method based on spatio-temporal evolution, which comprehensively considers an access position, communication time and access time as safety verification factors based on a multi-factor spatio-temporal perception algorithm. Meanwhile, effective defense can be provided for attacks such as verification information tampering and replay attacks possibly occurring in the verification process. Based on the characteristics that NFC application scenes are diversified and equipment types are various, a convenient and easy-to-use defense measure on a software level is designed, effective defense can be realized under the condition that existing equipment hardware does not need to be changed again, and the cost for realizing relay attack defense is reduced. And other extra work is not needed except for installation of the APP, so that user friendliness and implementability are greatly improved, and a feasible technical approach is provided for solving hidden dangers existing in NFC payment.

Description

technical field [0001] The invention belongs to the technical field of wireless communication information security, and relates to a near field communication (Near Field Communication, NFC) relay attack judgment, security authentication system and method, and in particular to a near field communication relay attack judgment system based on time-space evolution The invention relates to a security authentication system and method based on time-space evolution and RSA signature encryption. Background technique [0002] Near Field Communication (NFC) is an emerging wireless technology jointly promoted by Philips, Nokia, Sony and other famous manufacturers. It evolved from the integration of non-contact radio frequency identification (Radio Frequency Identification, RFID) and interconnection technologies. It combines inductive card readers, inductive cards and point-to-point functions on a single chip, and can communicate with compatible devices within a short distance. Identify...
