Design of a Public-Key Encryption Scheme Based on the Prime Region Elliptic Curve
Tong Hua-zhang · Computer Engineering and Science · 2008
The paper studies the existing basic public key encryption schemes,designs and realizes a public key encryption scheme based on the prime region elliptic curve.The scheme starts from the Diffie Hellman decision problem,together with the existence of collision-free hash functions.Under the circumstances of self-adaptive chosen ciphertexts and proclaimed-text attacks,it can be proved secure.
