A lightweight, (secure?), and relay-based Bluetooth Low Energy (BLE) protocol for fragmented, anonymous, and encrypted communication between devices.
It is an experimental protocol and not an official standard. No security checks by a specialized audit.
It is designed for:
- Device-to-device relaying.
- Secure data transmission (AES-CCM encryption, channels-based keys).
- Fragmentation of long messages into 13-byte payloads, linked via
Listfields. - Secure P2P messaging with fragmentation and relay (ex: chat).
- Very low debit: Send max 13 kilo-bytes (of data after compression) per 15 minutes.
Key Features:
- Easy and low provisioning.
- Low complexity (suitable for embedded and mobile devices).
- Anti-replay and integrity checks (TTL, AES-CCM
MIC).
Not Ideal for:
- Long-range IoT.
- High-throughput applications.
- Standardized, interoperable solutions.
- Large-scale deployments with dynamic group joining.
- PROTOCOL.md : Technical specification of the protocol.
- SECURITY.md : Know security issues.
