Through the combination of the public-key digital signature and the hash-chaining techniques, a new set of authentication protocols is proposed with the capability of arbitrating disputed bills. These protocols provide security services required by regular authentication protocols and are efficient in consideration of the specific Personal Communication Systems (PCS) environment.
