comment What is the difference between order of base point and curve order in EC?
@Mhsz: close; it turns out that finite Elliptic Curves need not be cyclic; for example, they can have $Z_2 \times Z_2$ as a subgroup; however that turns out to be cryptographically unimportant, and everything else you said is correct.

comment Availability of a simple limited PRNG algorithm
A PRNG is always repeatable given the same seed, whether or not it is cryptographic. What cryptographic means that if you don't know the seed, the output is indistinguishable from random (even if you are given the rest of the details of how the PRNG works)

comment homomorphic paillier cryptosystem vs Elliptic curve cryptosystem
Do you need the homomorphic properties? If you do, then using a system that gives you those properties would be indicated. If not, then you probably are better off with a crypto system that isn't malleable.
