Design And Implementation Of Product Digital Anti-counterfeiting System Based On AES

With the development of modern industrial technology and the improvement of production manufacture level,an increasing number of counterfeit goods appear in the areas of commodity production and circulation.It harm the interests of consumers and the reputation of genuine manufacturers seriously.Therefore,it's necessary to study the anti-counterfeit technology of the products.An useful product anti-counterfeiting system can not only prevent the spread of counterfeit and inferior goods effetely but also provide convenience for consumers.Product anti-counterfeiting system can play an important role in the process of against counterfeit and inferior goods only with the merits of security,availability,convenience and low cost.Encryption of information is basis of ensuring information security of the products in the product anti-counterfeiting system.An encryption is measured by its security,speed,and simplicity.AES as a new generation of Data Encryption Standard has the advantages of strong security,high performance,high efficiency,easy-to-use and flexible,etc.In 1997,NIST called for a new data encryption standard to the public,After three rounds of screening,Rijndael submitted by Vincent Rijmen and Joan Daeman who come from Belgium has been proposed the final algorithm.It has become the new Data Encryption Standard and which is widely used in various fields in the United States.The system which ensures the authenticity and safety of product information by designing a rational application model is based on AES.In practical applications,common product anti-counterfeiting system does not guarantee data security.It is vulnerable to authentication and access illegally.It also has some other problems.Some of the products used the MD5 encryption algorithm,but with the algorithm has been cracked it is no longer safe.Traditional framework and the shortcomings of the product anti-counterfeiting systems will be discussed in this paper.The system designed in this article proposed second encryption to ensure the product's security.A product digital anti-counterfeiting system was designed refer to the practical application of a product enterprise.Product serial number was encrypted once in the maintenance phase of the product information.The key management scheme is designed.The second encryption model has been used in the process of communication.It ensures that the process of information transmission in the network is security.This process does not need the user intervention.After the server received a query,the query results were sent to the users.This system has overcome the shortcomings of the traditional product digital anti-counterfeiting system.It ensures the benefits of the product manufacturers and consumers effectively.After testing,the system has higher security performance and faster run speed.
