Title
(EN) SYSTEM AND METHOD FOR DIFFERENTIAL ENCRYPTION
(FR) SYSTÈME ET PROCÉDÉ POUR UN CHIFFREMENT DIFFÉRENTIEL
Abstract
(EN) Some embodiments include a Trusted Security Module that creates secure connections using a set of split keys. Some embodiments include the creation of remote and local keys that are distributed to multiple devices. When the devices wish to communicate with each other, the remote and local keys are combined into connection keys to encrypt and decrypt messages. The remote and local keys may be combined in a variety of ways, including appending the remote key to the local key. A key mask may be used to create a connection key by using various combinations of bits from the remote key and from the local key. Other embodiments are described.
(FR) Conformément à certains modes de réalisation, l'invention concerne un module de sécurité sécurisé qui crée des connexions sécurisées à l'aide d'un ensemble de clés divisées. Certains modes de réalisation concernent la création de clés à distance et locale qui sont distribuées à de multiples dispositifs. Lorsque les dispositifs souhaitent communiquer les uns avec les autres, les clés à distance et locale sont combinées en clés de connexion pour chiffrer et déchiffrer des messages. Les clés à distance et locale peuvent être combinées d'une diversité de manières, comprenant le fait d'annexer la clé à distance à la clé locale. Un masque de clé peut être utilisé pour créer une clé de connexion par utilisation de différentes combinaisons de bits à partir de la clé à distance et à partir de la clé locale. D'autres modes de réalisation sont décrits.
