Abstract |
|
|
| To make users put much confidence in digital signatures, this paper proposes the first provably secure signature scheme
based on both factoring and discrete logarithms. The new scheme incorporates both the Schnorr signature scheme and the PSS-Rabin
signature scheme. Unless both the two cryptographic assumptions could be become solved simultaneously, anyone would not forge
any signature. The proposed scheme is efficient since the computation requirement and the storage requirement are slightly larger than
those for the Schnorr signature scheme and the PSS-Rabin signature scheme. |
