    The SDK provides high‑level primitives such as:

    /* Example: Create an encrypted flow */
sdde_flow_t *flow = sdde_flow_create("market-data",
    SDDE_PROTO_UDP,
    SDDE_CRYPTO_AES_GCM_256,
    SDDE_SCHED_FIFO,
    10e6 /* 10 Mbps guaranteed */);
/* Attach a network port */
sdde_port_attach(flow, SDDE_PORT_ID(0));

    Python bindings make rapid prototyping possible, e.g.:

    import sdde
engine = sdde.Engine()
flow = engine.create_flow(
    name="telemetry",
    proto=sdde.Protocol.QUIC,
    crypto=sdde.CryptoSuite.CHACHA20_POLY1305,
    qos=sdde.QoS.Deterministic(5e6)
)
flow.add_port("eth0")
engine.apply()

    | Objective | Description | |-----------|-------------| | Confidentiality | End‑to‑end encryption using post‑quantum ready algorithms (e.g., Kyber‑1024, Dilithium‑5) to protect data at rest and in transit. | | Integrity & Authenticity | Strong, verifiable signatures (Ed25519‑based) and hash‑based Merkle proofs to detect any tampering. | | Fine‑Grained Access Control | Attribute‑Based Access Control (ABAC) integrated with decentralized identity (DID) standards, allowing dynamic policy evaluation per request. | | Auditability | Immutable, tamper‑evident logs stored on permissioned ledgers (e.g., Hyperledger Fabric) for compliance (GDPR, HIPAA, NIS2). | | Scalability | Horizontal scaling via a micro‑service architecture and support for sharded data stores, enabling petabyte‑scale exchanges. | | Interoperability | Native support for widely used data formats (JSON‑LD, CBOR, Protobuf) and transport protocols (HTTP/2, gRPC, QUIC). | | Resilience | Built‑in fault‑tolerance mechanisms (automatic retry, multi‑region failover, erasure coding). |
