A Practical Elliptic Curve Public Key Encryption Scheme Provably Secure Against Adaptive Chosen-message Attack.
Huafei Zhu · 2003
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.
