comment Why are we not using multiple ciphers per message?
@Einar, not sure. Don't have the time to read and digest all that at the moment. Could be a useful question to ask on this site (or possibly another SE site).

comment Is Attribute based encryption sub-class of Identity based encryption
To add to what @DrLecter says, given an ABE scheme, you can construct an IBE scheme. You can't go the other way. The way to construct IBE from ABE is to give every participant in the system a single attribute. The attribute value is their identity.

You can't compute in parallel things that depend on the output of each other.

comment Homomorphic encryption based on XOR
@PaŭloEbermann re second comment, for $+$, I was talking about the typical way we do addition in finite fields of characteristic 2.

comment Homomorphic encryption based on XOR
@PaŭloEbermann re first comment, you mean $=(a\oplus b)\neq(a\oplus b)\oplus d$ right? I was more going along the question of the OP "can we derive b+a from any combination of c1 and c2". In this case, we can derive $a\oplus b$ from some combination of c1 and c2.

comment Homomorphic encryption based on XOR
So you are defining XOR in $\mathbb{Z}_p$ as bitwise XOR the two values together, then do a MOD p?

comment Is One Time Pad something like this?
@HerculesRockefeller don't worry about the English. That is something we can figure out by asking questions. If you edit your question with some of the information you posted in your comments here, I will take it off of "hold". Also, welcome to the site.
