Abstract(in English) We show a generalized formalization of an extended RSA-like elliptic curve cryptosystem over E_n(a,b):y^2≡x^3+ax+b(mod n).Here ,n is a product of form-free primes p and q For the RSA-like extended elliptic curve cryptosystem over E_n(0,b)or E_n(a,0),the decryption speed can be improved by using message-dependent decryption-keys.
