This paper presents a Public-key Cryptosystem on Conic Curve over Zn based on the difficulties of integer factorization and conic curve discrete logarithm.It is a conic analog of the public-key cryptosystem based on two private keys.Public-key Cryptosystem on Conic Curve over Zn is better than the original cryptosystem security,for the facility of plaintext embedding and the computing of rank and point on conic,this scheme has the advantages of speedy operation and easy realization,especially by using the NAF.
