Description
We present a new protocol for the following task. Given tow secrets a, b shared among n players, compute the value gab.
The protocol uses the generic BGW approach for multiplication of shared secrets, but we show that if one is computing “multiplications in the exponent” the polynomial randomization step can be avoided (assuming the Decisional Diffie-Hellman Assumption holds). This results in a non-interactive and more efficient protocol.
