Abstract

Multivariate based cryptography possesses the characteristic of high efficiency as well as resistance of quantum attack, which makes it become one of the main candidates of being possible alternative to conditional public cryptography in post-quantum ear. A new signcryption scheme based on Multivariate was proposed. The proposal combined MMI with Cyclic Rainbow and performed the encryption and authentication in a logical operation. By modifying MMI scheme with the idea of constructing the central mapping in HFE, the new scheme has brought the new construction. Compared with the original MMI scheme, our scheme is more secure than before and layering attack is not available. Besides, the key size of signcryption is smaller than MMI after modification, and makes encryption and signature become realizable at the same time. It also has the 300 bits ciphertext size, which is more efficient than others. The scheme could be used to encryption the structure big data.
