Abstract :
In the classical model of secret-key cryptology a relation between the measures for the security of a cipher is introduced. Concerning authentication theory the derivation of lower bounds on the opponent´s probability for deception is revisited. Especially it is shown that a certain generalization of the square-root bound for Ps is not possible and a new proof for the necessary and sufficient conditions for equality in this bound is given
