Design And Implementation Of Electronic Lock Security System Based On Smart Phone Controlled

Lock has a long history,since ancient times it has been an important daily necessities of human beings.With the development of science and technology,people’s demand for the security of locks is also constantly improved,followed by the emergence of password locks,IC card locks,electromagnetic locks,biological locks and other types of locks have also entered people’s lives.The Bluetooth lock based on mobile phone Bluetooth is studied in this paper.Electronic lock in the field of security technology prevention,overcome the mechanical password lock security performance of poor shortcomings,in technology and performance are greatly improved,the current electronic lock has been developed to the third generation,in addition to the key,password and fingerprint support,also can support mobile phone APP to unlock the function.Based on the above considerations,this paper carried out the design of Bluetooth lock unlocking system for smart phone APP.The main research work is as follows:First,the mobile phone user rights distribution.The electronic lock designed in this paper is mainly used in the daily life of residential users.Based on this,the user of electronic lock is divided into three rights: owner,manager and user.Based on these three aspects,the realization scheme of each module of the electronic lock system is discussed in detail.Second,the design of air-tight tube center.The password resource management center is the core of the whole system.According to the different roles,a variety of keys are designed to distribute permissions between roles and ensure the security of the whole system.Third,password module design.In this paper,SM2,SM3 and SM4 algorithms are used to ensure the correct generation of all kinds of keys and their corresponding purposes.Fourth,mobile security suite design.At present,the mobile phones mainly used by users are mainly divided into Android system and iOS system.Based on the dual systems,this paper has configured the corresponding security suite schemes respectively to ensure the normal operation of the mobile phone lock system.After the design of all the modules is completed,the performance test is carried outon the Android phone in this paper,and the test results show that the modules involved in this paper can run normally and stably.
