Claim Text:
1. A method comprising: receiving a packet at a first interface of an edge device; determining whether the first interface is configured with a reverse cryptographic map, wherein in response to a first determination that the first interface is configured with the reverse cryptographic map, determining whether the packet is protected by the edge device; a second interface performing a first operation, using the cryptographic map, on packets transmitted in an ingress transmission path direction into the second interface; the second interface performing a second operation, using the cryptographic map, on packets transmitted in an egress transmission path direction out of the second interface; the first interface performing the first operation, using the reverse cryptographic map, on packets transmitted in an egress transmission path direction out of the first interface; and the first interface performing the second operation, using the reverse cryptographic map, on packets transmitted in an ingress transmission path direction into the first interface.
