The McEliece public key cryptosystem and the Niederreiter public key cryptosystem are the two major branches of the code-based public key cryptosystem. It has been found that the difficult problems relied by these two systems are different from the syndrome decoding problem stated by Berlekamp et al. The Hamming weight of the error vector is fixed and known to the attackers in these two systems, which leading to the disclosure of information, and through which the attacker can implement an effective attack. In this paper, an improved vision of the McEliece public key cryptosystem was given, and a new code-based signature scheme is designed based on the new cryptosystem. As a result, we achieve a more secure variant of McEliece public key cryptosystem and a more secure code-based signature scheme with high security and fast signing speed.

AbstractWe develop a public-key cryptosystem based on invariants of diagonalizable groups and investigate properties of such a cryptosystem first over finite fields, then over number fields and finally over finite rings. We consider the security of these cryptosystem and show that it is necessary to restrict the set of parameters of the system to prevent various attacks (including linear algebra attacks and attacks based on the Euclidean algorithm).
