Security of the Cao-Li Public Key Cryptosystem

We show that the Cao-Li cryptosystem proposed in [1] is not secure. Its private key can be reconstructed from its public key using elementary means such as LU-decomposition and Euclidean algorithm. The Cao-Li public key cryptosystem was first proposed in [1]. It encrypts messages using a bilinear form that is chosen to permit easy decryption by the Chinese remainder theorem. Public key cryptosy...

Enhancing the Security of the McEliece Public-Key Cryptosystem

Berson pointed out that the McEliece public-key cryptosystem suffers from two weaknesses: (1) failure to protect any message which is encrypted more than once; and (2) failure to protect any messages which have a known linear relationship with one another. In this paper, we propose some variants of the McEliece scheme to prevent Berson’s attacks. In addition, we also propose some secure and eff...

The Security of the Gabidulin Public Key Cryptosystem

The Gabidulin Public Key Cryptosystem (PKC), like the well known McEliece PKC, is based on error correcting codes, and was introduced as an alternative to the McEliece system with the claim that much smaller codes could be used, resulting in a more practical system. In this paper an attack on the Gabidulin PKC is given which breaks it for codes of the size envisaged, destroying much of its adva...

On the Security of MOR Public Key Cryptosystem

For a finite group G to be used in the MOR public key cryptosystem, it is necessary that the discrete logarithm problem(DLP) over the inner automorphism group Inn(G) of G must be computationally hard to solve. In this paper, under the assumption that the special conjugacy problem of G is easy, we show that the complexity of the MOR system over G is about log |G| times larger than that of DLP ov...

The REESSE1+ Public Key Cryptosystem

In this paper, the authors give the definitions of a coprime sequence and a lever function, and describe the five algorithms and six characteristics of a prototypal public key cryptosystem which is used for encryption and signature, and based on three new problems and one existent problem: the multivariate permutation problem (MPP), the anomalous subset product problem (ASPP), the transcendenta...
