Patent Images
1. A system for transmitting encrypted image data comprising:
- a processor to;
select a virtual channel to be encrypted between an application processor and an image sensor during an initialization process;
transmit a virtual channel command corresponding to the selected virtual channel to the image sensor;
transmit an encryption key detection command to the image sensor, the encryption key detection command to indicate a technique to be used by the image sensor to detect an encryption key;
poll a register in the image sensor to verify the image sensor has stored the encryption key corresponding to the selected virtual channel; and
detect image data from the image sensor via the virtual channel, the image data encrypted with the encryption key.

Abstract
In one example, a system for transmitting encrypted data includes a processor to select a virtual channel to be encrypted between an application processor and an image sensor during an initialization process. The processor can also transmit a virtual channel command corresponding to the selected virtual channel to the image sensor. The processor can also poll a register in the image sensor to verify the image sensor has stored an encryption key corresponding to the selected virtual channel and detect image data from the image sensor via the virtual channel, the image data encrypted with the encryption key.
