A Comprehensive Whitepaper
RealTyme Cryptographic Architecture
Quantum threats are not a future problem — the harvesting has already started.
State-sponsored actors are intercepting and storing encrypted communications today, building archives to decrypt once quantum computing becomes viable.
This whitepaper presents RealTyme's full cryptographic architecture: the protocol stack, key management model, PKI design, and our NIST-aligned post-quantum transition. Built for organizations that cannot afford to get this wrong.
What You’ll Learn About
Cryptographic Architecture:
Why standard encryption is no longer sufficient
Understand the real-world threat of Harvest Now, Decrypt Later (HNDL) attacks, why provider-managed encryption creates structural vulnerabilities, and what client-side key sovereignty actually means for your organization's data.
How RealTyme's multi-layer protocol stack works
Explore the full communication protocol stack — from TLS 1.3 transport security and AES-256 end-to-end messaging, through WebRTC call encryption and secure device synchronization — and why each layer uses independent keys.
RealTyme's post-quantum transition: NIST-compliant and hybrid
Learn how RealTyme integrates ML-KEM-1024 and ML-DSA-87 alongside classical encryption in a hybrid model, so that both layers must be broken independently to access any data — and how this is already deployed, not just planned.
Why Download the RealTyme Cryptographic Architecture Whitepaper?
Organizations handling sensitive data with a shelf life beyond three years — governments, defense, financial institutions, healthcare, and legal — are already exposed to quantum risk today. This whitepaper gives security teams:
- A full breakdown of every cryptographic primitive used across messaging, calls, files, and device sync
- The PKI architecture behind RealTyme's Zero Trust mutual authentication
- A clear explanation of the hybrid post-quantum approach and NIST 2024 alignment
- Practical guidance for assessing your current encryption exposure
This whitepaper is designed for security architects, CISOs, and technical decision-makers who need depth, not marketing.
