Signature Schemes Based on Two Hard Problems Simultaneously
In 1994, Harn proposed a signature scheme based on the modified ElGamal's scheme and claimed that the security relies on both of the factorization and the discrete logarithm....

On the Fly Authentication and Signature Schemes Based on Groups of Unknown Order
Abstract. In response to the current need for fast, secure and cheap public-key cryptography, we propose an interactive zero-knowledge identification scheme and a derived signature...

On the Key Exposure Problem in Chameleon Hashes
Chameleon signatures were introduced by Krawczyk and Rabin, being non-interactive signature schemes that provide non-transferability. However, that first construction employs a c...

Factorization-Based Fail-Stop Signatures Revisited
Fail-stop signature (FSS) schemes are important primitives because in a fail-stop signature scheme the signer is protected against unlimited powerful adversaries as follows: Even i...

Solving a 676-Bit Discrete Logarithm Problem in GF(36n)
Abstract. Pairings on elliptic curves over finite fields are crucial for constructing various cryptographic schemes. The T pairing on supersingular curves over GF(3n ) is particula...
