Jul 23	comment	Additive ElGamal cryptosystem using a finite field Now this is an even nicer answer than Bristol's. Thank you very much @poncho. Too bad I can't give a +2. I'll leave his answer as accepted though, since he also provided a link to the python implementation.

May 21	comment	How were the number of rounds for different key sizes of AES selected? Maybe this article provides some explanations: research.microsoft.com/en-us/projects/cryptanalysis/aesbc.pdf The math behind the attacks that are detailed in the paper is a bit too much for me, though.

May 14	comment	DGK Cryptosystem Encryption Speedup That is a very good remark, @poncho. Let me try to explain the motivation: This is supposed to be a building block used for comparing private inputs. Alice will generate the keys, encrypt data with the public key and send ciphertexts to Bob, who performs homomorphic operations on them and then sends the results back to Alice. I'm working in the semi-honest model, so it is assumed that both parties are honest but curious and they follow the protocol no matter what. Now, this allows Alice to use parts of the private key for speeding up the encryption process, since Bob will not encrypt anything.
