Hi Guys,
i'm cryptodev engine to encrypt data so i want to know what is the maximum amount of data size can caam process. say i want to encrypt streaming data of high definition video.
thanks
Ganesh
This question is a bit vague. There is no global limit to the data
amount processed by CAAM. With a single descriptor, however, the
number of bytes that can be processed is limited by the size of the
LENGTH field of FIFO LOAD/FIFO STORE command, which is 16 bits. Some cipher modes,
namely counter-based, require a re-key after certain amount of processed
data to stay secure. This is, however, not a CAAM limitation.
Have a great day,
Platon
