A device may generate a first polynomial and a second polynomial, and may generate, based on the first polynomial, a primary path from a first network device to a second network device via a first set of intermediate network devices. The device may generate, based on the second polynomial, a secondary path from the first network device to the second network device via a second set of intermediate network devices, and may assign a point of the first and second polynomials to the device, to each of the first set of intermediate network devices and of the second set of intermediate network devices. The device may cause the primary path to be provided from the first network device to the second network device, and may cause the secondary path to be provided from the first network device to the second network device.

Providing quantum key distribution key delivery proof of origin and transit

A node may receive, from a quantum key-distribution (QKD) device, a first message that includes an identifier associated with a key. The node may send, to another node, a second message that includes the identifier and a request to perform at least one task. A node may receive, from the other node, a third message that includes information associated with performance of the at least one task by the other node and information indicating a time of performance. The node may receive, from the QKD device, a fourth message that includes the key and information indicating a time window associated with the quantum key; wherein the fourth message is received after expiration of the time window. The node may process, based on the fourth message, the third message to determine whether the third message is valid and thereby cause one or more actions to be performed.

Delayed quantum key-distribution

An apparatus may (1) receive, at the service provider's network, at least one flow of network traffic from a remote device included in a user's private network, (2) identify, within the flow of network traffic, at least one potentially non-unique private address that represents the remote device with respect to the user's private network, (3) determine, at least one unique routable address that represents the remote device with respect to the service provider's network based at least in part on a network interface assigned to the user's private network, the potentially non-unique private address, and the address-translation table, and then (4) translate, in response to determining the unique routable address, the potentially non-unique private address to the unique routable address to facilitate routing return network traffic to the remote device in connection with the flow of network traffic. Various other apparatuses, systems, and methods are also disclosed.

Systems and methods for virtualizing customer-premises equipment

A computer-implemented method for virtualizing customer-premises equipment may include (1) receiving, at a service provider's network, at least one flow of network traffic from a remote device included in a user's private network, (2) identifying, within the flow of network traffic, at least one potentially non-unique private address that represents the remote device with respect to the user's private network, (3) determining at least one unique routable address that represents the remote device with respect to the service provider's network based at least in part on a network interface assigned to the user's private network and the potentially non-unique private address, and then (4) translating the potentially non-unique private address to the unique routable address to facilitate routing return network traffic to the remote device in connection with the flow of network traffic. Various other systems, methods, and computer-readable media are also disclosed.
