Cryptography plays an important role in confidentiality, privacy protection, integrity verification. The most widely used public key cryptosystem including RSA system and elliptic curve cryptography. Since quantum algorithm and quantum computer are both developed rapidly, the current public key cryptosystem and signature scheme are under threaten, including RSA and elliptic curve cryptography. In this paper, an internal perturbation based on two-dimension chaos system is proposed to improve the security of traditional multivariate public key signature system. The outputs of central map in multivariate public key cryptosystem are acted as initializers for a two dimension chao system. When two sequences are calculated in chaos system, the corresponding elements are multiplied one by one. When both of multivariate public key cryptosystem and chaos system are estimated, the outputs of the two system are added to get the final signature. Because of the nonlinearity and unpredictability of chaos system, the proposed signature system is able to resist bilinear attack and rank attack and as a consequence, the proposed signature scheme is more secure than traditional multivariate public key signature systems.
