The Multivariate based Certificateless Hybrid Signcryption Scheme

摘要：

　　With the development of quantum computer,multivariate public key cryptography withstanding quantum attack has became one of the significant research focus.Based on multivariate public key cryptography,a new certificateless multi-receiver hybrid signcryption scheme has been proposed.The proposal could handle arbitrary length messages by employing randomness reusing and hybrid encryption,as well as keeping security.In the random oracle model,the scheme could withstand the IND-CCA2 adversary and UF-CMA adversary under the hardness of Multivariate Quadratic (MQ) problem and Isomorphism of Polynomials (IP) assumption.The scheme has less computation overhead and higher transmission efficiency than others.It reduced the 33% ciphertext data compared with the existed similar scheme.
