Abstract
(EN)
A method for transmitting data in a computer network is provided, which comprises, at a first node of the network: receiving a computing puzzle from a puzzle server node of the network distinct from the first node; determining a solution to the puzzle for transmitting a message to a second node of the network distinct from the puzzle server node; and transmitting data to the second node, wherein the transmitted data comprises a message and the determined solution to the puzzle.
(FR)
L'invention concerne un procédé de transmission de données dans un réseau informatique, qui comprend, au niveau d'un premier nœud du réseau : la réception d'un puzzle informatique à partir d'un nœud de serveur de puzzle du réseau, distinct du premier nœud; la détermination d'une solution au puzzle pour la transmission d'un message à un second nœud du réseau, distinct du nœud de serveur de puzzle; et la transmission de données au second nœud, les données transmises comprenant un message et la solution déterminée, destinés au puzzle.
