VKX Wallet Security Architecture
Post-Quantum Readiness and Hybrid Signing Model
Overview
The VKX Wallet implements an incremental security architecture designed to bridge the gap between current cryptographic standards and future post-quantum requirements. This multi-layered model focuses on enhancing transaction integrity and device authorship without modifying underlying blockchain protocols or compromising user self-custody.
The architecture is built upon three foundational pillars:
- Modular Security Layer: Flexible integration of security modules.
- Post-Quantum Readiness Layer: Implementation of lattice-based cryptography.
- Hybrid Signing Model: Concurrent signing with ECC and PQC.
