Detailed Description

The MPDC network functions.

This header defines the public network functions and data types used by MPDC to perform secure network operations. These operations include certificate announcement, network convergence, registration and update of network nodes, key exchange, remote signing, revocation, and topological queries.

Each network message is encapsulated in a packet that includes a header (with a time-stamp, sequence number, and flag), a payload, and a digital signature that covers the payload and header. This ensures integrity, authenticity, and protection against replay attacks.

Note: This header declares only the public API. Many internal functions (such as those for constructing and validating packet headers, hashing, signing, etc.) are defined as static in the implementation file.

Example:

mpdc_network_announce_request_state req_state;
req_state.list   = &global_topology_list;
req_state.rnode  = &remote_node;
req_state.sigkey = local_signing_key;
 
mpdc_protocol_errors err = mpdc_network_announce_broadcast(&req_state);
if (err != mpdc_protocol_error_none)
{
    // Handle error.
}
