In this thesis we study a class of authentication codes with secrecy. We obtain the maximum
success probability of the impersonation attack and the maximum success probability of the
substitution attack on these authentication codes with secrecy. Moreover we determine the
level of secrecy provided by these authentication codes. Our methods are based on the theory
of algebraic function fields over finite fields. We study a certain class of algebraic function
fields over finite fields related to this class of authentication codes. We also determine the
number of rational places of this class of algebraic function fields.
