comment Analogue encryption algorithms
Frequency hopping isn't really encryption. It's main purpose is not even confidentiality of the message content, but avoiding jamming (DoS attack) and might make it harder to find the position of the sender.

comment Pseudorandom function library
I'd first use HMAC-SHA-2 to reduce the input to a fixed size key and then use that key in a stream cipher to obtain arbitrary length output.

@xxx I have deleted my comment mentioning your original name. But please refrain from vandalizing the question or my answer. You asked the question and can't take it back.

You could use a mode that only requires encryption, such as CTR mode.
