METHOD AND CORRESPONDING TELECOMMUNICATION NETWORK FOR SECURE DATA TRANSMISSIONS BASED ON GRAPH DATABASE

摘要

The present invention relates to a method (100, 200, 300, 400) of communication between nodes in a telecommunications network. In particular, each node maintains a copy of a shared digital ledger, is identified by a respective identification code and implements a software application configured to manage the transmission of data packets and maintain the shared digital ledger. The method (100, 200, 300, 400, 500) comprises that each sending node of a data packet executes the steps of: a. memorizing a list of identification codes, each identification code identifying a respective node comprised in a subset of nodes of the network, b. identifying (103; 200, 500) a receiver node to which to transmit said data packet, c. generating (105) a data packet to be delivered to a recipient node, d. transmitting (107) to the first node of said minimum sequence of nodes the data packet, e. issuing (109) a request to the network nodes to record said data packet transmission in the distributed ledger, and when a data packet is received, the method requires that each receiver node, other than the recipient node of the data packet, repeats at least the steps b., and D.. Advantageously, the step a. of identifying (103, 200; 500) a receiver node to which said data packet is transmitted comprises: - generating (203; 503) a graph database in which a respective arc connects the sender node or the receiver node, different from the recipient node, to each node of the network of which the identification code is comprised in the list of identification codes of the sender node or the receiver node, other than the recipient node, and - selecting (209; 505) the receiver node among the nodes of said graph database. Furthermore, if it is not possible to identify a receiver node, the method further comprises the steps of: - analyzing a contact list stored in the sending node, each contact in the contact list being associated with a corresponding device; - if at least one contact is identified in which is associated with a device having installed said software application but not enabled to exchange packets in the telecommunication network, enabling said device to exchange packets as a temporary node of the telecommunication network, and - selecting said device as receiver node of the data packet.
