1. An apparatus comprising:
an image signal processor; and
a memory storing instructions which, when executed by the image signal processor, cause the processor to:
receive a packet from an image sensor along a physical data connection;
determine a virtual channel associated with the packet;
determine, based on the virtual channel, a first secure domain for the packet, wherein the first secure domain is selected from a plurality of secure domains accessible via the physical data connection, wherein determining the first secure domain includes determining that a first domain identifier for the first secure domain corresponds to a virtual channel identifier, wherein the image sensor is one of a plurality of image sensors and the virtual channel identifier identifies the image sensor from among the plurality of image sensors; and
route the packet within the first secure domain.
