ONS (Object Name Service) access method, terminal, server and system

Abstract

The invention discloses an ONS (Object Name Service) access method, terminal, server and system; the method comprises the steps as follows: a requesting terminal first selects mapping information of a to EPC-IP (Electronic Product Code-Internet Protocol) from mapping information of K to EPC-IP before requesting inquiry of a target EPC (Electronic Product Code) code, and obtains a EPC codes; the requesting terminal randomly generates at least one legal EPC code; the requesting terminal combines the a EPC codes, the at least one randomly generated legal EPC code and the target EPC code to be inquired so as to form an EPC code set and transmits the EPC code set to an ONS server; and the requesting terminal receives an IP set returned by the ONS server and verifies the IP set; and if the IP set passes the verification, the requesting terminal believes that the returned IP value corresponding to the requested target EPC is correct. The ONS access method disclosed by the invention is achieved without a cryptography algorithm and has the advantages of small calculation amount, high speed and short response waiting time; and moreover, the authenticity of ONS data and privacies of EPC inquirers can be effectively protected.

Description

technical field [0001] The invention relates to the data security of the Internet of Things under the electronic product code network architecture, and in particular to an ONS access method, terminal, server and system for protecting the authenticity of ONS data and the privacy of inquirers. Background technique [0002] In the Internet of Things, the product has an electronic label, and the electronic label contains the unique code of the product, that is, the electronic product code (EPC: Electronic Product Code) such as figure 1 As shown, it is the existing ONS query process. The reader reads the electronic tag on the item, obtains the EPC code, and transmits it to the Savant system through the computer. The Savant system then uses the object name resolution server (ONS: Object Naming Services) to find the location where the product information is stored, that is, the IP address. ONS indicates to the Savant system the server that stores the relevant information of this p...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method that does not require the use of cryptographic algorithms for the defects of large amount of calculation and slow speed caused by the need to use cryptographic algorithms such as encryption and signature when authenticating the returned IP in the prior art. An ONS access method, terminal, server and system that protects the authenticity of ONS data and the privacy of inquirers with small amount of calculation, fast speed and short response waiting time
