comment DSA, RSA, ECDSA etc - which one is cheapest for signing?
ECDSA should be faster than BLS, since it can use a special prime for the finite field arithmetic. And if you need short sigatures, Zhang/Safavi-Naini/Susilo should be faster than BLS since it uses a fixed point multiplication.

comment How much stronger is RSA-2048 compared to RSA-1024?
@user27296 it's implicit in Reid's answer. It's not $2^{1024}$ times harder because GNFS can attack it faster than simple brute force. It's $2^{32}$ times harder, as mentioned.

comment How are Elliptic Curve Cryptography and Pairing Based Cryptography related?
Yes, but the only alternative I know is PBC using elliptic nets, which are related but different to ECC.
