Image signal processor supporting multiple security domains on a shared physical link

A method, comprising:

• receiving, by an image signal processor, a packet from an image sensor along a physical data connection;
• determining, by the image signal processor, a virtual channel associated with the packet;
• determining, by the image signal processor 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;
• and
• routing, by the image signal processor, the packet within the first secure domain.

A non-transitory, computer-readable medium storing instructions which, when executed by an image signal processor, cause the image signal 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;
• and
• route the packet within the first secure domain.

An image capture device comprising:

• a first image sensor;
• a second image sensor;
• an image signal processor;
• a first shared physical link coupling the first image sensor to the image signal processor and coupling the second image sensor to the image signal processor;
• and
• a memory storing instructions which, when executed by the image signal processor, cause the image signal 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;
• and
• route the packet within the first secure domain.
