description A device for communicating with another device of the same type via an emulated quantum channel (205), the device comprising: a central processing unit (101); a memory (102); a hardware quantum random number generator (103); and a network interface (105) for communicating via the emulated quantum channel (205). The central processing unit (101) is configured to provide (100A) quantum key distribution (QKD) keys to the other device, by: generating (502), by means of the quantum random number generator (103), at least one QKD key; generating (503), by means of the quantum random number generator (103), a token; sending the token, via the network interface (105), to the other device; receiving, from the other device, an encrypted token; decrypting (505) the encrypted token with the public key of the other device; comparing (506) the decrypted token with the generated token; upon determining that the decrypted token corresponds to the generated token, encrypting (507) the at least one QKD key with the public key of the other device and sending, via the network interface (105), the encrypted at least one QKD key to the other device.
