FTU Mobile Maintenance App Dual-factor Security System Based On SMS Dynamic Password

The identity authentication technology with dynamic password two-factor security system has become a mature technology in the field of electronic commerce.Since the FTU in the distribution network automation system is installed on the column,it is very inconvenient to maintain and repair system,but the smart phone is very flexible and convenient as a maintenance terminal.However,the national economy and people's livelihood rely on a safe and stable electric power distribution network.There is absolutely no tolerance for unauthorized cell phone to take control of the professional equipment.Therefore,the App used for FTU maintenance must undergo the strictest security assessment before operating the FTU.This paper carries out relevant technical research on this subject,which has certain theoretical significance and high practical value.Based on the research of related studies,the technical principle,operation process and technical objectives of dynamic password two-factor asynchronous identity authentication technology have been mastered.On this basis,further technical research was carried out until a specific solution of the problem is found.Aiming at the requirement of authentication confidentiality,the TEA algorithm was selected to encrypt and decrypt authentication codes based on the research of relevant studies.And the operation principle and coding implementation of the algorithm were analyzed concretely.The experimental program was designed to verify the algorithm.And the classification of TEA algorithm was completed for software development on server and mobile terminal.Based on the results of the above technical research,the hardware environment of the identity authentication server is built using the communication method of the mobile phone short message.The VC++ integrated development environment was used to design the identity authentication server software,which realized the construction of the software framework,the underlying communication driver,the mobile phone short message application development and the dual-machine hot standby function,completing the design and the development of the project software.After completing the design and implementation of the software,a comprehensive verification test has been carried out in the lab,proving that the designed software meets the requirements of user technical specifications.Project research and software des ign use mature technology in the field of e-commerce to solve practical problems in the field of industrial production,reflecting the certain innovation of project research.This paper contains 19 figures,2 frames and 56 references.
