Summary: 
In this paper, we present previously unproposed schemes for encryption with anonymity and ring signature by applying two techniques. That is, we construct a key-privacy encryption scheme by using N-ary representation, and a ring signature scheme by using the repetition of evaluation of functions. We analyze precisely the properties of these schemes and show their advantage and disadvantage.
