Abstract: | We discuss a modification of the Cramer-Shoup strong-RSA signature scheme. Our proposal also presumes the strong RSA assumption (and a collision-intractable hash function for long messages), but -without loss in performance- the size of a signature is almost halved compared to the original scheme. We also show how to turn the signature scheme into a "lightweight" anonymous (but linkable) group identification protocol without random oracles. |
