WebRTC2: The Definitive Standard for Secure Communication

Built for privacy. Designed for power. Engineered for sovereignty.

Executive Summary​

In the rapidly evolving landscape of digital communication, the choice of a cryptographic protocol determines whether your organization achieves true privacy or remains vulnerable to surveillance. While platforms like Telegram promote their custom MTProto protocol, a rigorous technical analysis reveals critical security flaws that fundamentally compromise user protection.

WebRTC2, in stark contrast, is engineered from the ground up to embody the highest standards of cryptographic security, transparency, and user empowerment — positioning it as the demonstrably superior solution for enterprise-grade secure communication.

Key Takeaway

WebRTC2 leverages only vetted cryptographic primitives (noble, BIP39) while competitors rely on proprietary, unaudited protocols that introduce unnecessary security risks.

The Fundamental Flaws of MTProto: A Critical Examination​

Telegram's proprietary MTProto protocol, despite aggressive marketing claims, exhibits significant architectural and cryptographic shortcomings that undermine its security foundations.

1. Violating Core Cryptographic Principles​

"Don't Invent Your Own Cryptography" — A Violated Principle

Telegram's decision to develop its own encryption protocol instead of leveraging established, industry-vetted solutions represents a fundamental error in cryptographic engineering. MTProto was "not built by cryptographers" and uses "existing cryptographic primitives but in non-standard ways."

This approach bypasses essential peer-review and standardization processes crucial for robust cryptographic protocols.

2. Dangerous Complexity Over Security​

Complexity Violates the KISS Principle

MTProto is characterized by a "complex structure: many layers, temporary keys, authentication keys, DC migration, etc." This inherent complexity significantly hinders "auditing and verification."

The "Keep It Simple, Stupid" (KISS) principle is foundational in cybersecurity design — simplicity reduces the attack surface and minimizes implementation errors.

3. Critical Security Vulnerabilities​

Compromised Confidentiality and Integrity (IND-CCA Insecurity)

A core technical criticism against MTProto is that it "is not IND-CCA secure" (Indistinguishability under Chosen-Ciphertext Attack). This critical flaw means that "one can turn any ciphertext into another ciphertext that decrypts to the same message."

MTProto also:

  • "Does not satisfy authenticated encryption (AE) definitions"
  • "Does not authenticate messages (except via IGE)"
  • The "lack of a MAC in the protocol made MTProto vulnerable to padding length extension attacks and last block replacement"

4. The Perfect Forward Secrecy Illusion​

Unlike protocols like Signal, "MTProto does not provide full Perfect Forward Secrecy by default." This means:

  • If an authentication key is compromised, old messages can be decrypted
  • Only Telegram's "secret chats" offer PFS — the vast majority of cloud chats lack this critical security property
  • If server-side keys are ever compromised, all historical conversations become vulnerable

5. Centralization and Trust Dependencies​

In Telegram's default cloud chats, "messages are decrypted by Telegram itself, meaning there is no true E2E by default." This means:

  • Telegram has "full access to them"
  • Introduces a trusted third party that can potentially access, store, or be compelled to disclose user data
  • Even "secret chats" are "still tied to Telegram's server infrastructure"

6. Documented Vulnerabilities and Audit Gaps​

"Telegram sometimes runs bug bounty programs, but there are no truly deep crypto audits from reputable groups (NCC, Trail of Bits, etc.). This is a red flag."

Recent critical example: Remote Code Execution (RCE) vulnerability (CVE-2023-45312) in the mtproto_proxy component with a CVSS score of 9.8/10 demonstrates that the overall MTProto ecosystem is fragile.

The Signal Protocol: Industry Benchmark​

The Signal Protocol is widely recognized as the gold standard for secure messaging, stemming from its adherence to established best practices in cryptographic design.

Signal's Strengths​

  • Designed by real cryptographers using well-vetted open specifications
  • End-to-end encrypted communication for all messages by default
  • Provides robust "forward secrecy" and "post-compromise security"
  • Entirely open source for public inspection and auditing

Signal's Limitations​

  • Centralized server dependency for signaling
  • Limited self-hosting options for enterprise deployment
  • Phone number requirement ties identity to centralized servers

WebRTC2: Next-Generation Cryptographic Architecture​

WebRTC2 not only meets but surpasses cutting-edge standards by building on proven cryptographic primitives, prioritizing default security, and championing user sovereignty.

1. Vetted Cryptographic Foundation​

Leveraging Only Proven Primitives

WebRTC2 commits to using "only vetted cryptographic primitives (noble, BIP39)" — ensuring the protocol is built upon the most robust cryptographic components available.

Noble Cryptography Libraries​

  • Zero or minimal dependencies for supply chain security
  • Highly readable TypeScript/JS code for independent verifiability
  • Meticulously crafted suite of auditable cryptographic libraries

BIP39 Standard for Secure Key Management​

  • Widely adopted and standardized method for generating mnemonic phrases
  • Represents complex cryptographic keys in human-readable format
  • Incredibly high level of guessing resistance

2. Built-in WebRTC Security Architecture​

Encryption by Default

WebRTC inherently mandates encryption for all media and data streams:

  • Datagram Transport Layer Security (DTLS) for secure key exchange
  • Secure Real-time Transport Protocol (SRTP) for media stream encryption
  • Perfect Forward Secrecy built into WebRTC's DTLS implementation

3. Self-Sovereign Identity (SSI)​

Empowering Complete User Control

WebRTC2 pioneers "self-sovereign identity, independent of server trust" — representing a paradigm shift in user control over digital identity.

Decentralized Trust Benefits​

  • Full control and ownership of personal data
  • Eliminates reliance on centralized authorities for identity management
  • Credentials are cryptographically secured and managed directly on users' devices
  • Zero-knowledge server architecture — servers never access content or files
