Cryptanalysis on 2 Dimensional Subset-sum Public Key Cryptosystem

Hwang et al. proposed an ElGamal-like scheme for encrypting large messages, which is more efficient than its predecessor in terms of computational complexity and the amount of data transformation. They declared that the resulting scheme is semantically ...

Murakami and Nasako proposed a knapsack public key cryptosystem in2008. They claimed that their proposal is secure against some known attacks. In this paper, we propose a cryptanalytic attack on the cryptosystem. We use a heuristic method to show that ...

Certificateless cryptography is a new type of public key cryptography, which removes the certificate management problem in traditional public key cryptography and the key escrow problem in identity-based public key cryptography. Multi-proxy signature is ...
