Research And Implementation Of The Third Party Traceability Platform Based On RSA Algorithm

With the continuous development of science and technology,people's living standards have gradually improved.The quality and safety of commodities,along with the improvement of people's consumption level,has become a social problem that people pay close attention to.From the current social situation,it is difficult for consumers to obtain accurate traceability information.It is impossible to know the specific information of every link of commodity from raw materials to transportation and finally to sales.It provides opportunities for counterfeiters to produce counterfeit and inferior products.Enterprises urgently need an integrated and practical anti-counterfeiting traceability mechanism to regulate market order.This paper summarizes and elaborates the domestic and foreign research findings of anti-counterfeiting traceability system,and through the research and analysis of data encryption,anti-counterfeiting traceability and other related technologies.Combining the optimized RSA algorithm with the new traceability model,a traceability anti-counterfeiting system based on RSA algorithm is constructed.Based on the actual project,the related system is elaborated and implemented in detail.The main research contents are as follows:(1)Through the research and analysis of the traditional RSA algorithm,aiming at its slow speed,low efficiency and security problems,the traditional RSA algorithm is improved.The traditional RSA algorithm is improved to combine CRT's four-prime RSA algorithm.By increasing the number of prime numbers and combining with Sun Tzu's theorem,the decimal multiplication is used to calculate the key,so that its operation efficiency is higher than that of the large multiplication.On this basis,a new parameter x is introduced to correlate with n,which replaces the transfer of the original parameter n in the public key.This makes it difficult for an attacker to attack the parameter n and improves the security of encryption..(2)On the basis of traditional traceability model,a new anti-counterfeiting traceability model is constructed,which uses two-dimensional code as the carrier of information transmission.The new traceability system integrates production,storage,transportation,sales and query of enterprise products.Unifying the traceability of commodities in various fields,changing the traditional cumbersome and single traceability model.(3)By introducing the optimized RSA encryption algorithm into the new anti-counterfeiting traceability model,the data security and reliability of the new anti-counterfeiting model are further improved..(4)An anti-counterfeiting traceability system based on RSA optimization algorithm is designed and implemented.The system includes a series of designs of mobile end and back end.Aiming at some drawbacks and shortcomings of the current traceability system,such as QR Code traceability easily tampered with information,traceability information is not comprehensive,a stable operation,complete information retrieval,strong functional scalability and strict supervision and control of commodity anti-counterfeiting traceability system is established.(5)Finally,the paper gives a summary and outlook of the full text,and puts forward some problems to be solved and the focus of follow-up work combined with the experimental content and research situation of this subject.In summary,this paper combines the new anti-counterfeiting traceability model with the improved RSA algorithm,and according to the actual needs of the new anti-counterfeiting traceability system,designs and implements the core functions of the system,and has been applied in practice.
