Aegis Conference Security System SM66
R&D Background
Withthe accelerationofglobalization,informationsecurityissueshavebecome increasinglyprominent.Asanimportanttoolforinformation exchange,the security ofaudio andvideo conferencing hasbecome a critical issue.Inrecentyears, frequentinformationleakageincidentsbothdomesticallyand internationally,such as the U.S."PRISM scandal"and the“Black Swan" incident on Jiangsu Province's publicsecurityvideospecial network,havefullyexposed theseverethreatsposed by audioandvideoinformationleakagetonationalsecurityandsocialstability. Especiallyunderthe currentcomplexandever-changing international situation, hostileforceshavebeencontinuouslyintensifying theirpenetration and intelligence theftagainstChina,withmeetingleaks accountingforashighas80% of suchincidentsThereforebuildingasecureandcontrollableaudioandvid conferencingsolutionhasbecome anurgentnecessity.
To addressthischallenge,Soundking Group,guided bynational strategicneeds, hasinvestedsignificantresources indeveloping an audio andvideoconferencing security management system.This system aims toprovide a comprehensive and highlyreliableaudioandvideoconferencing solutionfornational keydepartments andcritical industries.Byleveraginginnovativetechnical architectures and stringentsecuritymanagementmechanisms,thesystemfundamentallyresolves thesecurityrisksinherentintraditionalconferencingsystems,effectively countering external attacks and internal leakagerisks.Itprovidesa solid technologicalfoundationforstrengtheningthenational informationsecurity defense.

For audio andvideo conferencing security,Soundkinghasdeveloped theShendun ConferenceSecuritySystemSM66,anadvancedsecuritymanagementsystemthat integrates cutting-edgetechnology and multiplefunctionalities.The system isbuilt around corecomponentssuchastheShendunConferenceSecurityPlatform, conferencesecurityuserterminals,MCUmulti-channelconferencesecuritysignal distributors,distributeddisplay-endconferencesecurityterminals,andconference securityoperation andmaintenanceterminals.Itemploys advancedencryption algorithms,real-timekeytransformation,terminalwatermarkembedding, ultrasonicmixing,andmultiplesecuritymechanismstocomprehensivelysafeguard conferenceinformationsecurity.Simultaneously,itachievesefficientand convenientaudioprocessing and operations,offeringusersasecure andreliable conferencing solution.
