Registration step In this step both the TMIS and the patient perform the following steps: x The TMIS generates < D , E , E0, n, c> and constructs the elliptic curve equation 2 3Y xx D E over Fc such as E0 is a point from the elliptic curve 2 3 Y xx D E and, , ND EÂ then the TMIS Chooses 1 1 n 1d O d , calculates 01 A E O and sends < D , E , E0 ...
