Title:ResearchandImplementationofMulti-LevelKeyDerivationinVideoSurveillance
Abstract:
Withtherapiddevelopmentofvideosurveillancesystems,ensuringthesecurityandintegrityofcapturedvideodatahasbecomeincreasinglyimportant.Akeyaspectofachievingthisistheeffectivemanagementandprotectionofencryptionkeysutilizedinvideosurveillancesystems.Inthispaper,weexploretheconceptofmulti-levelkeyderivation,whichinvolvesthederivationofmultipleencryptionkeysbasedonamasterkey.Wediscussthesignificanceofmulti-levelkeyderivationinenhancingthesecurityofvideosurveillancesystemsandproposeanimplementationframeworkforthisapproach.
1.Introduction:
1.1Background:
Videosurveillancesystemsarewidelyusedinvariousapplications,includingpublicsecurity,trafficmonitoring,andcommercialsettings.Thesecurityofcapturedvideodataiscrucialtopreventunauthorizedaccess,tampering,andensuretheprivacyofindividualswhomayappearinthefootage.Encryptionplaysavitalroleinprotectingvideodata,andtheeffectivemanagementofencryptionkeysisakeyrequirement.
1.2Objectives:
Theprimaryobjectiveofthispaperistoresearchandimplementamulti-levelkeyderivationapproachforvideosurveillancesystems.Thisapproachaimstoenhancethesecurityofencryptionkeysandensuretheintegrityofcapturedvideodata.Throughthisresearch,weaimtoprovideacomprehensiveunderstandingofmulti-levelkeyderivationandproposeapracticalimplementationframework.
2.Multi-LevelKeyDerivation:
2.1Overview:
Multi-levelkeyderivationinvolvesderivingmultipleencryptionkeysfromasinglemasterkey.Thederivedkeysareusedforvariouspurposes,suchasencryptingvideodata,securingcommunicationchannels,andaccessingspecificfunctionalitieswithinthevideosurveillancesystem.Thisapproachprovidesanadditionallayerofsecuritybyminimizingtheexposureofthemasterkey.
2.2AdvantagesofMulti-LevelKeyDerivation:
-Enhancedsecurity:Withmulti-levelkeyderivation,evenifonederivedkeyiscompromised,thesecurityofotherkeysremainsintact.Thishelpspreventunauthorizedaccesstovideodata.
-Granularaccesscontrol:Differentlevelsofderivedk
