A Practical Elliptic Curve Public Key Encryption Scheme Provably Secure Against Adaptive Chosen-message Attack

huafei zhu

Abstract: We study elliptic curve cryptosystems by first investigating the schemes defined over $Z_p$ and show that the scheme is provably secure against adaptive chosen cipher-text attack under the decisional Diffie-Hellman assumption. Then we derive a practical elliptic curve cryptosystem by making use of some nice elliptic curve where the decisional Diffie-Hellman assumption is reserved.
