An authenticated encryption scheme provides a mechanism of signing and encrypting simultaneously, and furthermore, the receiver can verify and decrypt the signature at the same time. Tseng et al. proposed two efficiently authenticated encryption schemes which can check the validity of the sent data before message recovery, but in fact their schemes cannot achieve completely the function. In this article, we point out the flaw and propose an improved scheme of revision.
