A many-to-one function is called collision-resistant if it is infeasible to find two distinct inputs which correspond to the same output. Collision-resistant functions are used for a lot of cryptographic schemes such as encryption, digital signature and identification. In this paper, we consider a few cryptographic schemes using two collision-resistant functions based on factoring: The Schmidt-Samoa function and the Shamir-Tauman function.
First, we consider commitment schemes using these functions and discuss the security of the schemes. We also compare them with the one using a collision-resistant function based on discrete logarithm. Then, we present a scheme to improve the efficiency of the fail-stop signature
using the Schmidt-Samoa function for multiple messages. We also prove the security of this scheme. |
