### Paper: Comment on cryptanalysis of Tseng et al.??s authenticated encryption schemes

Authors: Yi-Hwa Chen Jinn-Ke Jan URL: http://eprint.iacr.org/2005/054 Search ePrint Search Google Recently, Xie and Yu proposed a forgery attack on the Tseng et al??s authenticated encryption schemes and showed that their schemes are not secure in two cases: the specified verifier substitutes his secret key, or the signer generates the signature with these schemes for two or more specified verifiers. In addition, Xie and Yu made a small modification for the Tseng et al??s schemes and claimed that the modified schemes can satisfy the security requirement. However, we show that the modified schemes are still insecure.
