Abstract
Disclosed are a data transmission method, an authentication method, and a server. The data transmission method performed by a node among a plurality of nodes connected in a hierarchical structure includes generating a node identity (ID) comprising at least one from among a virtual address for identifying the node and a group key for identifying a group to which the node belongs, generating a signature of the node by using at least one from among the node ID and information about a previous node adjacent to the node, and transmitting a data packet to a server using a node chain formed based on signatures of the nodes.

A data transmission method performed by a node among a plurality of nodes connected in a hierarchical structure, the method comprising:
- generating a node identity (ID) comprising at least one from among a virtual address for identifying the node and a group key for identifying a group to which the node belongs;
- generating a signature of the node by using at least one from among the node ID and information about a previous node adjacent to the node;
- and
- transmitting a data packet to a server using a node chain formed based on signatures of the nodes.
An authentication method performed by a server connected to a node among a plurality of nodes connected in a hierarchical structure, the method comprising:
- registering node identities (IDs) of the nodes including at least one from among virtual addresses for identifying the nodes and group keys for identifying groups to which the nodes belong;
- registering signatures of the nodes generated from combinations of at least one from among the node IDs and information on previous nodes adjacent to the nodes;
- and
- authenticating a data packet transmitted along a node chain formed based on the signatures of the nodes by using the registered signatures.
A server connected to a node among a plurality of nodes connected in a hierarchical structure, the server comprising:
- a register configured to:
- register node identities (IDs) of the nodes, the node IDs comprising at least one from among virtual addresses for identifying the nodes and group keys for identifying groups to which the nodes belong;
- and
- register signatures of the nodes generated from combinations of at least one from among the node IDs and information about previous nodes adjacent to the nodes;
- and
- an authenticator configured to authenticate a data packet transmitted along a node chain formed based on the signatures of the nodes by using the registered signatures.
