Classification: CPC H | IPC H

Claim 7:
8. A communication gateway device, comprising:
a first port and a second port; and
a processor configured to carry out a method including:
receiving a communication request, from a first device at the first port, for performing a first cryptographic data communication protocol, the communication request being directed to a second device that is reachable from the second port,
determining the first cryptographic data communication protocol is registered as unsafe in the gateway device;
executing, in accordance with the determining the first cryptographic data communication protocol is registered as unsafe in the gateway device:
the first cryptographic data communication protocol between the first device and the gateway device, and
a second cryptographic data communication protocol, which is not recorded as unsafe in the gateway device, between the gateway device and the second device,

wherein the first cryptographic data communication protocol and the second cryptographic data communication protocol are executed sequentially to communicate data between the first and second device via the gateway, and
wherein the first cryptographic data communication protocol registered as unsafe in the gateway device is a cryptographic data communication protocol that is not safe against key reconstruction by a quantum computer.
