Title
(EN) TRUSTED COMMUNICATION IN TRANSACTIONS
(FR) COMMUNICATION DE CONFIANCE DANS DES TRANSACTIONS
Abstract
(EN)
Trusted communication between a first computing device and a second computing device in a transaction process is established as follows. A communication channel is established between the first computing device and the second computing device. The first computing device provides a secure communication to the second computing device, this secure communication comprising cryptographic material encrypted by a first cryptographic method. The second computing device decrypts the secure communication using a key already available to it. The first and the second computing device then communicate where trusted communication is required by a second cryptographic method using the cryptographic material. A suitable first computing device and second computing device are also described.

La présente invention concerne une communication de confiance entre un premier dispositif informatique et un second dispositif informatique dans un processus de transaction. Un canal de données secondaire est établi entre le premier dispositif informatique et le second dispositif informatique. Le premier dispositif informatique fournit une communication sécurisée au second dispositif informatique, cette communication sécurisée comprenant un matériel cryptographique crypté par un premier procédé cryptographique. Le second dispositif informatique décrypte la communication sécurisée à l'aide d'une clé déjà disponible pour ce dernier. Le premier et le second dispositif informatique communiquent ensuite où une communication de confiance est requise au moyen d'un second procédé cryptographique utilisant le matériel cryptographique. L'invention concerne également un premier dispositif informatique et un second dispositif informatique appropriés.
