Solitude Labs is a decentralized security platform designed for distributed and edge‑based systems such as IoT devices, industrial control networks, and critical infrastructure. Instead of relying on a traditional perimeter, the platform implements a data‑centric zero‑trust architecture: each device is assigned a unique cryptographic identity, signs every data packet, and maintains a local ledger of which other devices it is authorized to communicate with. Key technical functions include: - Peer‑to‑peer authentication and encryption using Hybrid Public Key Encryption (HPKE), eliminating the need for centralized authentication servers. - Granular role‑based (RBAC) and attribute‑based (ABAC) access controls that enforce least‑privilege policies at the device level. - Network‑agnostic operation that works over any transport medium, with low‑latency communication and resilience to network outages. - Decentralized key management and independent cryptographic engines to avoid single points of failure. The solution can be delivered as plug‑and‑play hardware gateways or integrated as software into existing control systems, and it targets use cases in energy grid management, manufacturing, water utilities, and data center operations.
