The Design And Implementation Of Logistics Management System Based On AES

With the rapid development of China's economy and information technology,the Internet has played an indispensible role in people's lives,and people's way of life is becoming more and more convenient.Online shopping is one of the important manifestations.It promotes the rapid development of mobile business providers with the characteristics of convenience,speed and cost performance.The quality of logistics service has become an focus concerned by consumers and businesses.At present,the problems that restrict the rapid development of logistics enterprises mainly include:the leakage and sale of user information;the untimely notice of pick-up;the long queue time of pick-up;the loose of pic-kup verification;the low efficiency of logistics distribution;the high logistics cost.In order to solve the above problems,a logistics management system based on improved AES(Advance Encryption Standard)algorithm is designed.The system consists of a new logistics management system and a pickup verification APP.The main functions of the new logistics system include:registration and login,order information encryption,order information decryption,order QR code,goods tracking,pickup message,etc.The main functions of APP include:online mail,online pick-up,order list,order details,site query.In this paper,the performance of AES algorithm and chaotic system of each dimension is studied.Aiming at the problem of small AES key space and low algorithm security,three kinds of four dimensional hyperchaotic system are used as candidate key generator,and random function is used to generate key generator randomly.The chaotic sequence with good randomness generated by the key generator is combined with AES to encrypt the order information,so that the user privacy information can be protected at the source.The new logistics management system uses the improved AES algorithm to solve the problem of user information leaking and selling.The system automatically generates the pick-up number to avoid the secondary coding of the express station,reduces the workload of the staff,and saves the logistics cost.The server uses instant messaging technology to send message to the addressee,which saves the time of notification,reduces the cost of logistics,and improves the operational efficiency of logistics enterprises.It is of practical significance for the development of logistics enterprises to pickup verification APP online pickup verification,improve the safety and timeliness of the pick-up,solve the bottleneck of restricting the development of logistics enterprises.
