In this paper, we design a novel one-way trapdoor function, and then propose a new multivariate public key cryptosystem called TOT, which can be used for encryption, signature and authentication. Through analysis, we declare that TOT is secure, because it can resist current known algebraic attacks if its parameters are properly chosen. Some practical(More)
Multivariate Public Key Cryptosystem (MPKC) is one of post-quantum cryptosystems which can potentially resist quantum computer attacks. It has increasingly been seen by some as a possible alternative to public key cryptosystems RSA, ECC, etc., which are widely in use today. Moreover, MPKC schemes are in general much more computationally efficient than(More)
