We present an analysis of some known cartesian authentication codes and their modification into authentication codes with secrecy, with transmission rateR=r/n, wheren= 2, 3, ..., and 1 ≤r≤n− 1 using (n−r)(r+ 1)q-ary key digits. For this purpose we use a grouping technique.Essentially the same key grouping technique is used for the construction of codes that withstand spoofing attacks of orderL≥ 2. The information rate of this scheme is alsor/n, and it requires (L+r)(n−r)q-ary key digits. Moreover these codes allow that previously transmitted source states can be reused.
