However, these schemes didn't protect the users' identities while authenticating the users, even though user anonymity is an important issue in many e-commerce applications.

The moment-transfer approach is a standard tool for deriving limit laws of sequences of random variables satisfying a distributional recurrence. However, so far the approach could not be applied to certain “one-sided" recurrences with slowly varying moments and normal limit law. In this paper, we propose a modified version of the moment-transfer approach(More)
