Abstract
A gateway device between a first and second communication network outside the gateway device handles communication between a first device in the first network and a second device in the second network. When the gateway receives a communication request from the first device, directed to the second device, for performing a first cryptographic data communication protocol, the gateway determines whether the first cryptographic data communication protocol is registered as unsafe in the gateway device, and/or registered as safe, in particular whether it is safe against key reconstruction by a quantum computer. When the first cryptographic data communication protocol is not registered as unsafe in the gateway device, and/or registered as safe, the gateway device forwards messages exchanged as part of execution of the first cryptographic data communication protocol between the first and second device. When the gateway determines that the first cryptographic data communication protocol is registered as unsafe in the gateway device, and/or not registered as safe, the gateway device executes the first cryptographic data communication protocol between the first device and the gateway device, and executes a second cryptographic data communication protocol, which is not recorded as unsafe in the gateway device, and/or registered as safe, between the gateway and the second device, whereby the first and second cryptographic data communication protocol are executed sequentially to communicate data between the first and second device via the gateway device.
