XSOC StreamShield

XSOC E2EE overlay for Zoom, Teams, and Google Meet. DSKAG + EBP epoch rekeying. No PKI. No static keys.

XSOC StreamShield adds a cryptographic end-to-end encryption overlay to your Zoom, Microsoft Teams, and Google Meet video calls directly in the browser. No app install required. No changes to your existing workflow. HOW IT WORKS StreamShield intercepts WebRTC media frames after codec encoding but before network transmission using the RTCRtpScriptTransform API (Chrome/Edge 110+). Every audio and video frame is encrypted with XSOC's native cipher before leaving your device. The receiving participant's extension decrypts in real time. The video conferencing platform's servers see only ciphertext. KEY TECHNOLOGY DSKAG (Deterministic Symmetric Key Agreement Generator): Both participants derive identical session keys locally without any key exchange over the wire. No key material ever transits the network. 7.998 bits/byte entropy. EBP (Encrypted Broadcast Protocol): Epoch-based rekeying every 30 seconds. Old frame keys are zeroed each epoch. Forward secrecy by design. NIE (Nexus Identity Engine): Cryptographic attestation gates key derivation. Only policy-compliant, attested participants can join the encrypted session. WASM sandbox isolation ensures keys never enter the JavaScript heap. Post-Quantum Ready: FIPS 203 ML-KEM channel establishment as a toggleable mode. WHAT THE PLATFORM SEES Nothing. Even a fully compromised Zoom/Teams/Meet server sees only encrypted frames. There is no key escrow, no key server, no trust in the platform. USAGE 1.
