Research And Implementation Of Security Scheme In Mobile Video Surveillance System

Nowadays,security issues are increasingly being taken seriously by people.As an important part of security systems,video surveillance has been widely used in all walks of life.With the development of technology,video surveillance is about to enter the era of mobility.For mobile video surveillance,the complexity of the cyberspace and the openness of the user terminal equipped with the Android system make it a lot of security threats.This situation seriously jeopardizes the safety and rights of users.Therefore,the security status of the mobile video surveillance system itself has received special attention.This thesis is based on the "Smartphone Security Video Surveillance System" project of the 30 th Institute of China Electronics Technology Group,Chengdu 30 Kaitian Co.Ltd.and researches the security technology of the mobile video surveillance system.This thesis analyzes the existing security technologies and finds that most of the current systems only have identity authentication and authorization as a security guarantee mechanism.And the identity authentication part is complex.There are various problems in practical applications and it is difficult to adapt to the security requirements of developing mobile video surveillance system.In order to solve the above problems,this thesis first researches the existing identity authentication technology,and gives a method of using IBC technology to replace the original PKI technology for identity authentication.Secondly,for the current status of mobile video surveillance systems,there is currently no content encryption.After this study,this thesis proposes a new security scheme.The new scheme has increased the encryption part of video data,and has carried on deep research and realization to the encryption part.Encryption algorithm is improved when entropy-encoded encryption is used to implement content encryption.The improved algorithm reduces complexity and improves security.In the implementation of the above security scheme,the encryption algorithm technology as the basis and core has been highly valued by the country.In order to get rid of the use of foreign encryption technology in various security applications,China has independently developed a series of domestic passwords in recent years,which has a high level of security.Under the vigorous promotion of the National CryptographyAdministration,more and more industries have begun to widely adopt the secret algorithm.In the above process of identity authentication and authorization,this thesis analyzes and compares the state secret SM series,introduces the SM9 encryption algorithm into the IBC technology,and presents an identity authentication scheme based on the IBC technology.This method realizes the localization of IBC technology.In terms of content security,the ZUC algorithm is introduced into the content encryption section,and a content encryption method for entropy encoding encrypted video data is presented.Finally,the above security scheme is tested.The test results show that the system improves the identity authentication and authorization capabilities.The increased encryption of video content greatly enhances the security performance of the system.
