Research And Realization Of The Dual System Architecture And Software Security Technology Of The Police Terminal Hardware In The Supervision Site

Smart prison construction is an important part of the national e-government construction.The construction of the prison security technology prevention system is an important technical guarantee for the safety and standardization of law enforcement in the supervision place.The design and improvement of the police terminal are the safety and speed of each police officer.Comprehensive technical equipment occupies an important position in the security system of the prison.However,at present,the communication equipment in each supervision place is limited to police communication and intercom.The hardware configuration is low,too old,the device has a single function,and the performance is poor.The simple call in prison mode has simple functions,and the prison mode only has Call function,high communication delay.The radio uses a public frequency band,and its security is extremely poor,while the mode switching function of the police communication equipment is not stable,there are some security loopholes,and it is still based on the operator's public frequency band.This subject is mainly aimed at the security vulnerabilities and work requirements of the police security system in the existine sepervisory premises.Based on the main problems of the implementation and application development of the current police terminal system,a set of software and hardware integrated police premises terminal system is designed and implemented.The design and implementation of the police terminal in the supervision site is mainly divided into two parts,the hardware part and the software part.The hardware part realizes the optimal design and implementation of the system on the police terminal under the Android system,which is mainly divided into three functional modules:including a dual system module based on the Mobi-DualSystem trusted operating architecture and a dual system switching method,A key generation method based on an improved tent-AES algorithm used with a trusted operating space and a data destruction method.The software part is designed,developed and implemented for applications based on instant messaging and voice communications at the application level.The functional structure of the software system mainly includes account address book module,instant communication module,voice call module,voice-to-text copy record module,data cloud backup module,local data automatic cleaning module and monitoring system access module.After testing and field test analysis,the hardware part of the dual system based on the Mobi-DualSystem trusted operation architecture designed in this paper satisfies the design requirements of police terminals in the regulatory premises,with good performance,and the improved Tent-based AES algorithm is applicable In the process of dual system switching and data encryption,encryption security and encryption performance have been tested and performed well.Part of the software security police application meets the original design intention and the actual needs of the supervision site.Various functions have been tested to achieve good results,and the server side has excellent performance after high load performance testing.The overall functions and performance of the system's software and hardware have performed well,and have reached the design goal of the police terminal's software and hardware system in the supervision place.
