comment AES and Homomorphic Encryption
@Dillinur I don't think I am missing the point at all. Your comment relates to one minor sentence at the end of my answer. The rest of my answer is exactly what you say. Also, I disagree that with your assertion that "no trick is needed". If I take a long string of integers separated by commas and encrypt it directly with AES-CBC it is going to be very hard for the cloud to do very useful operations with that.

comment Why is the public/private key length used in libsodium so much shorter than needed for RSA
They likely aren't using RSA. Likely some sort of elliptic curve cipher.

After reading this comment where you said "80 years" I was thinking, "man, dutch grammar school is insane" :)

comment cipher text only attacks on deterministic homomorphic encryption schemes
If they have the public key, why not just use it to encrypt 1?

I updated the question's formatting, etc. If I inadvertently changed the meaning of the question, please let me know.

Does the attacker know the public key?

comment What is more efficient, pairing based cryptography or non pairing based cryptography?
I think if you add more context to the question to make it more specific, we can reopen this question.

@superpelican you can if you have the time. It doesn't cover AES though.

Why is simplicity the only criteria? Also, how did you come up with the 5 listed ciphers?

This has been voted closed as "unclear". What is your question? At the moment it looks like a simple dump of a homework assignment or something along those lines. Can you clarify what you are stuck on in doing this assignment?

Interesting, glad you found the answer.
