Embodiment 1

[0027] figure 2 The structure of the electronic product code access control system provided by the first embodiment of the present invention is shown, and for the convenience of description, only the parts related to the first embodiment of the present invention are shown.

[0028] In Embodiment 1 of the present invention, the access control system of the electronic product code includes: a registration machine 14, which is used to establish public parameters and a master private key, and when a registration request is received and the registration request meets the conditions, output the first private key and the second private key. 2. Private key; the electronic product code information system 12 is used to store the ciphertext of the electronic product code information and the ciphertext of the corresponding key, and after receiving the label information access request, store the ciphertext of the electronic product code information and the ciphertext of the corresponding k...

[0034] Figure 4 It shows a flow chart of the access control method of the electronic product code access control system provided in the third embodiment of the present invention and described in the first or second embodiment.

[0035] In Embodiment 3 of the present invention, the access control method of the access control system of the electronic product code includes:

[0036] Step S1: The registration machine establishes the public parameters and the master private key. Step S1 may further include the following steps:

[0037] S11: Set the security parameter λ.

[0038] S12: Define the first multiplicative group whose order is a prime number p and the second multiplicative group get the first multiplicative group The generator g of and defines the bilinear map e:

[0039] S13: Set attribute space For each attribute in the attribute space choose randomly and calculate

[0040] S14: Random selection and calculate u=g β , w=e(g,g) α .

[0041] S15: Est...

Abstract

The invention belongs to the technical field of Internet of Things information security, and provides an access control system and an access control method of an electronic product code. The system and its access control method apply the revocable attribute encryption technology based on the third party, store the electronic product code information representing the item information in the form of cipher text, and control the access of the tag reader by setting the attribute revocation list in the arbitration machine The decryption authority realizes the ciphertext access control to the electronic product code information, which makes up for the lack of privacy protection in the current electronic product code identification system. At the same time, since attributes are used as the basic unit of access control, the access control system can realize fine-grained access control, prevent any unauthorized tag reader from illegally accessing item information, and effectively guarantee the security of item information stored in EPCIS. Privacy.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things information security, and in particular relates to an access control system of an electronic product code and an access control method thereof. Background technique [0002] Electronic Product Code (EPC) is an item identification code that uses a radio frequency electronic tag as a carrier and realizes information transmission by means of the Internet. Only the EPC is carried on the radio frequency electronic tag, and the analysis of the EPC needs to be completed through the identification system. [0003] figure 1 The electronic product code identification system provided by the prior art is shown. First, the label reader scans the label with the electronic product code attached to the item, extracts the EPC stored on the label, and sends it to the middleware; after the middleware processes the EPC, it submits it to the object name resolution server through the Internet (Object Name...
