What changed
USPTO published patent application US20260100831A1 covering encrypted segment routing methods in multi-region fabric networks. The application describes a method where authorized segment hop devices decrypt encrypted segment lists within packets to determine next hop addresses, replacing destination addresses in unencrypted headers before forwarding.\n\nThis patent application is informational for technology companies and network equipment manufacturers developing segment routing or network fabric technologies. It establishes priority dates and creates potential freedom-to-operate considerations for companies working in similar routing encryption spaces. No compliance obligations are created by this publication.

Abstract
In one embodiment, an illustrative method herein may comprise: receiving, at a device in a computer network, a packet having an unencrypted header and an encrypted segment list, wherein the device is an authorized segment hop device and wherein a destination address within the unencrypted header matches an address of the device; decrypting, by the device and in response to the destination address within the unencrypted header matching the address of the device, the encrypted segment list to expose at least a next segment hop address in the encrypted segment list; replacing, by the device, the destination address within the unencrypted header with the next segment hop address; and forwarding, from the device, the packet toward the next segment hop address along with the encrypted segment list.
