PPT-Efficient Generation of Cryptographically Strong Elliptic

Itay Khazon Eyal Tolchinsky Instructor Barukh Ziv Introduction Public key cryptography is based on the hardness of several mathematical problems such as factoring and DLP The public key protocols in use today are based on the discrete logarithm problem over This problem can be solved in subexponential time. and gives concentrates points inside domain (A0) or at the ends (A) De By .
