Currently the linking authority is fully trusted, which is often not desirable..In this paper, we firstly in

Salt and iteration count are used in practice to significantly increase the workload of such attacks. These techniques have also been specified in widely adopted industry standards suc

Using some recoding algorithms for the scalar, we can reduce the number of divisor class additions during the process of computing the scalar multiplication. On the other side, the divisor doublings will stay the same for all kinds of scalar multiplica

Existing schemes completely or partially leak a piece of information: the lengths of the removed substrings. Such length information could be crucial in many applications, especiall
