Title

(EN) MESSAGE AUTHENTICATION

(FR) AUTHENTIFICATION DE MESSAGE

Abstract

(EN) Disclosed herein is a method of provisioning a message authentication protocol in a system of connected devices, the method comprising, by at least one of the connected devices: generating a private key and a public key; transmitting the public key to each other connected device; generating, by a sequence of hash operations using the private key, a hash tree, wherein each leaf node of the hash tree can have two or more values, each of the two or more values being associated with a respective nonce value, and wherein each leaf node has a hash computed from the concatenation of the respective nonce values; signing a root of the hash tree with the private key; and transmitting the root and the root signature to each other connected device.

(FR) L'invention concerne un procédé de fourniture d'un protocole d'authentification de message dans un système de dispositifs connectés, le procédé comprenant les étapes suivantes réalisées par au moins un des dispositifs connectés : produire une clé privée et une clé publique ; transmettre la clé publique à chaque autre dispositif connecté ; produire, par une séquence d'opérations de hachage en utilisant la clé privée, un arbre de hachage, chaque nœud feuille de l'arbre de hachage pouvant avoir au moins deux valeurs, chacune des au moins deux valeurs étant associée à une valeur de nonce respective, et chaque nœud feuille ayant un hachage calculé à partir de la concaténation des valeurs de nonce respectives ; signer une racine de l'arbre de hachage avec la clé privée ; et transmettre la racine et la signature de racine à chaque autre dispositif connecté.
