Abstract :
An authenticated encryption scheme with (t, n) shared verification was published in 1998 by Hsu and Wu under the assumption that all participant verifiers were honest. An improvement to Hsu-Wu´s scheme is proposed in this paper. This improvement can prevent some verifier from cheating others. It also requires fewer transmitted messages. The security of the improved scheme is based on the factoring and discrete logarithms
