Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Identity-Base Cryptography (IBC) is a new type of public key cryptography. Its characteristic is that the user's public key is naturally related to the user's identity. When using IBC for digital signature and verification, it only needs to use the signature algorithm to generate a digital signature, and use the corresponding verification algorithm to verify the digital signature, without using additional mechanisms (such as digital certifica...

Abstract

The invention discloses an anti-fake verification method, device and system and an anti-fake certificate based on IBC (Identity-Base Cryptography). The method comprises: obtaining the certificate identifier in the chip of a certificate to be verified; sending random numbers to the chip; receiving a digital sign returned by the chip according to the random numbers, verifying the digital sign according to the random numbers, locally stored issuer public parameters, the certificate identifier and a pre-stored IBC verification algorithm. According to the invention, offline anti-fake verification is carried out to the certificate without installing and verifying a digital certificate for many times; the operation flow is simplified; the verification time is shortened; and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting verification, in particular to an IBC-based anti-counterfeiting verification method, device, system and anti-counterfeiting certificate. Background technique [0002] In order to prevent counterfeit goods, counterfeit money, counterfeit bills and other items from confusing the real ones, many items that need to be verified during use (such as tickets, certificates, banknotes, etc.) will adopt certain anti-counterfeiting methods. numbers, photos, barcodes, etc.), which are easy to be copied and forged, and have low security. [0003] In order to improve anti-counterfeiting performance, smart key devices are commonly used for anti-counterfeiting at present. Smart key devices, such as chips, are added to items that need to be verified, and some information that needs to be verified is stored in the chip. During verification, the chip communicates with the verification device. The informa...
