What LTP is

The Low-Throughput Protocol (LTP) is Sonata’s experimental transport framing and integrity layer for distributed node communication. It defines binary message serialization formats, chunk transfer mechanics, and CRC-based corruption detection. LTP was originally designed to support Hub/Body communication in a distributed swarm architecture.

LTP should be read as a laboratory transport foundation, not as a complete secure networking stack. Its current validated scope is message framing, round-trip serialization, chunk transfer, and accidental corruption detection.

Tested message types

The following message types passed serialization and deserialization tests:

• Handshake: Connection initialization between nodes
• Hello: Node identification and capability advertisement
• Task: Work unit description and dispatch
• Result: Completed task output delivery
• Chunk request / response: Block-level data transfer
• Error: Error condition reporting

All message serialization/deserialization round-trips passed validation.

Chunk transfer

Binary chunk serialization was benchmarked:

• 1 MiB chunk serialization: near-zero measurable latency
• Wire size: 1,048,610 bytes per chunk
• Transfer format uses fixed binary headers with raw byte bodies (no Base64/JSON encoding)

CRC mismatch detection

CRC-based integrity verification passed tests. Mismatched chunks were correctly detected and reported. This provides accidental corruption detection at the transport-framing level, but it is not a substitute for cryptographic authentication, encryption, or adversarial tamper resistance.

Current security boundary

LTP currently provides:

• ✅ Message serialization and deserialization
• ✅ Chunk transfer with CRC-based corruption detection
• ✅ Binary framing with fixed headers

It does not provide:

• ❌ Encryption (all payloads are plaintext)
• ❌ Authentication or identity verification
• ❌ Authorization or access control
• ❌ Replay attack protection
• ❌ Secure key exchange or key management
• ❌ Cryptographic message signing

What must be added for secure distributed operations

Before LTP could support secure distributed operations, the following would need to be implemented and validated:

• TLS or equivalent encrypted transport channel
• Node identity certificates and mutual authentication
• Signed message payloads with provenance tracking
• Authorization layer (RBAC or capability-based)
• Replay protection and session freshness guarantees
• Audit trail for all operations
• Secure session and key management

Claim boundary

The public claim for LTP is intentionally narrow: Sonata has a working binary framing and integrity-checking transport foundation for distributed-node experiments. It does not currently claim secure networking, production-grade distributed execution, or adversarial robustness.
