I want to use AES CTR with a random IV, as this would be the easiest way for me. I have a cryptographic module, that supports true random number generation. Due to compatibility, I must use AES CTR. The module also supports a monolithic counter, but its max value is quite low and might be too low for my use-case. RFC 3686 states the following:

WebMay 4, 2016 · And the IV serves as the ciphertext input for the first block. If the first block were not secure with a known IV, the second block would not be secure with known ciphertext, and ciphertext is known. So if the second block is secure, the IV need not be kept secret. – David Schwartz May 4, 2016 at 21:54 WebIn a cryptographic algorithm, an IV is used as a "starting state."
