Solidity bilinear pairing
WebApr 10, 2015 · We proposed an efficient ring signature scheme in the bilinear groups for perfect anonymity, which is provably secure in the random oracle model under the co-CDH assumption. Our scheme is the first ring signature scheme whose computational complexity for pairing computations is independent of the ring size, i.e., it requires only two pairing ... WebFrom the documentation: success := call (sub (gas, 2000), 8, 0, add (input, 0x20), mul (inputSize, 0x20), out, 0x20) This means we can just check equality of two pairings in a …

More precisely, it is not existentially unforgeable under an adaptive chosen-message attack. Let's consider the following efficient adversary A: it queries the S i g n s k ( ⋅) oracle for the digital signatures on m 1, m 2, where m 2 := m 1 + 1. The received signatures are σ 1 = g 1 x 1 m ...
