Abstract

The invention discloses an electronic tag anti-fake authentication method. A logic system in an electronic tag chip comprises an authentication order receiving, sending and control processing circuit, a one-time write-in sealing storage circuit, a one-time write-in read-only storage circuit, a read-write storage circuit, a random number generator circuit, an encryption and decryption operational circuit and a one-way hash function operational circuit. An anti-fake authentication system comprises an initializing sub system and an authentication sub system. The anti-fake electronic tag can pass the authentication of the authentication sub system only after the successful initialization of the initializing sub system. According to the electronic tag anti-fake authentication method, the problems that a low-cost logically encrypted electronic tag is prone to illegal copying, internal storage information is prone to illegal falsification and steal, and space transmission data are prone to illegal eavesdropping and resetting are solved.

Description

technical field [0001] The invention relates to an anti-counterfeiting electronic label, in particular to an anti-counterfeiting authentication method for an electronic label, belonging to the technical fields of electronic labels and information security. Background technique [0002] Mifare series contactless IC card is a classic IC card product of NXP. It mainly includes Mifare1 S50 (1K bytes) and S70 (4K bytes), which are widely used in access control, campus and public transport fields, as well as the simplified version of Mifare Light and the upgraded version of MifarePro4 chip models. Among these types of chips, except for Mifare Pro, they all belong to logical encryption cards, that is, there is no independent CPU and operating system inside, and the IC cards completely rely on built-in hardware logic circuits to achieve security authentication and protection. It adopts the ISO14443A international protocol standard. On-site reading and writing operations need to pas...
