Title
(EN) REPLAY PROTECTION NONCE GENERATION
(FR) GÉNÉRATION DE NONCE DE PROTECTION CONTRE LA REPRODUCTION
Abstract
(EN)
Devices and techniques for replay protection nonce generation are described herein. A hash, of a first length, can be produced from a first input. A first subset of the hash can be extracted as a selector. A second subset of the hash can be selected using the selector. Here, the second subset has a second length that is less than the first length. The second subset can be transmitted as a nonce for a freshness value in a replay protected communication.
(FR)
L'invention concerne des techniques de génération de nonce de protection contre la reproduction. Un hachage, d'une première longueur, peut être produit à partir d'une première entrée. Un premier sous-ensemble du hachage peut être extrait en tant que sélecteur. Un second sous-ensemble du hachage peut être sélectionné à l'aide du sélecteur. Ici, le second sous-ensemble possède une seconde longueur qui est inférieure à la première longueur. Le second sous-ensemble peut être transmis sous la forme d'un nonce pour une valeur de fraîcheur dans une communication protégée contre la retransmission.
