NEXT-GEN PRIVATE COMMUNICATION

PENA.

The Visionary & High-Impact "Why Pena? Because today's security cannot withstand tomorrow's threats." In an era where privacy is eroding and quantum computing renders standard encryption obsolete, Pena emerges as the Digital Fortress of the Future.

Real Peer-to-Peer (P2P) architecture with robust Post-Quantum cryptography. Pena is far more than a messaging platform; it is a Super App where secure communication, total data defense (VPN & Anti-Malware).

Supported Platforms

Android iOS

Application & Security Architecture

The application architecture encompasses the cryptographic layer, backend services, API, database, network controls, client-side components, and supporting infrastructure working seamlessly to ensure system functionality, security, and robustness.

01 Cryptography

  • PQC & E2EE

    Utilizes ML-KEM (CRYSTALS-Kyber) compliant with NIST FIPS 203 as part of the key exchange mechanism for E2EE.

  • Authentication

    Implements Ed25519 for digital signatures, authentication, and communication integrity verification.

  • Hash & KDF

    Uses SHA-3/Keccak-based cryptographic functions for hashing and key material derivation.

  • Payload Encryption

    Data and payloads are protected using authenticated symmetric encryption at the application layer.

  • Randomness

    Employs CSPRNG for the secure generation of cryptographic materials.

  • Architecture

    Adopts a modular and post-quantum ready cryptographic design, with implementation details managed at the application level.

02 Application

  • Crypto Library

    Supplies robust cryptographic primitives to ensure the confidentiality and integrity of communication channels and application data.

  • Embedded SDK

    Incorporates essential software development kits to seamlessly orchestrate backend services, data persistence, caching mechanisms, system monitoring, and push notifications.

  • API & Real-Time Communication

    Leverages RESTful APIs and persistent connections to enable low-latency, real-time data exchange.

  • Permission

    Implements stringent authentication, role-based authorization, and dynamic rate limiting to safeguard system resources against unauthorized access.

  • Native Library

    Executes cryptographic operations natively on the client device, ensuring sensitive key material remains isolated and secure.

  • Key Establishment

    Facilitates a secure, asynchronous key exchange protocol to guarantee forward secrecy and interoperability across diverse client environments.

Post-Quantum Encryption

Post-Quantum Encryption is a cryptographic approach designed to remain secure even in a future where quantum computers become powerful enough to break traditional encryption.

In PENA, post-quantum encryption is implemented through:

"Security is not about how much has been proven on paper, but how deeply an idea can protect what is truly invaluable."

"Keamanan bukan tentang seberapa banyak yang telah dibuktikan di atas kertas, melainkan seberapa dalam sebuah gagasan mampu melindungi apa yang tak ternilai."
