Design Of Encrypted Transmission And Storage Platform For Streaming Media Based On Embedded

With the landing of 5g and AI,the demand of streaming media technology for embedded computing platform in the new communication era is greatly increased,which not only requires the improvement of hardware performance and the update of software version,but also with the enhancement of people's sense of confidentiality,the security performance has become a major criterion for the development of the platform.Therefore,this paper will focus on video conference,which is a first-class media application point,to build a special embedded platform for streaming media transmission and storage and design encryption scheme for it,committed to providing a considerable hardware choice for the development of new intelligent streaming media.In this paper,the hardware selection and software design are described from three aspects: transmission,storage and encryption of streaming media data in the new video era.In terms of hardware design,the embedded SOC architecture of DSP + arm is adopted,and tms320dm8148 chip based on Da Vinci Technology produced by TI company is selected as CPU to build peripheral auxiliary circuit and complete hardware design;in terms of software,firstly,the development environment is built,the Linux operating system is transplanted,and initial preparations are made,then the streaming media software architecture based on mcfw video framework is designed,and synchronous audio is inserted The frequency data is collected,compressed,encoded and packaged.Finally,the streaming media open source server live555 is transplanted to transmit and store the package.The network transmission interface is Gigabit rmgii mode,supporting RJ45 interface,and the storage device supports pluggable USB portable storage device.After the design of the streaming media platform,the encryption module is designed.In this paper,a new steganography encryption technology is selected(the data to be encrypted is embedded into the compressed video data through the related algorithm).Firstly,the framework of minimizing distortion is introduced into the traditional steganography algorithm,then the cost function based on the edge feature is constructed,and the steganography rules are designed for data steganography At last,a steganography process based on embedded platform is proposed to provide pseudo code of steganography algorithm.At the end of the paper,the independent hardware performance test and the complete system running test of the streaming media platform are carried out,and the experimental conclusion is given,which proves that the streaming media platform is not only at a high level in hardware configuration,but also can be used as a platform choice for streaming media applications such as video conference,and the high-performance DSP core supports the implantation of audio and video algorithm.The system has a certain computing power and believes in the new intelligence In the information age,it can also be used as the basic hardware platform.
