| Research Abstract |
I proposed and implemented anonymous authentication scheme with resistant to the coercion. The proposed scheme includes user public key into certification that is issued from administrator using pairing technique. And then, the user proves his certification with knowledge of his private key to the verifier. Therefore, the user cannot transfer his certification to a third party without disclosing his private key. It was able to perform all processes from registration to the authentication in about 10seconds.
