This paper is concerned with a particular type of attack against CBC-MACs, namely forgery attacks, i. e. attacks which enable an unauthorised party to obtain a MAC on a data string. Existing forgery attacks against CBC-MACs are briefly reviewed, together with the effectiveness of various countermeasures. This motivates the main part of the paper, where a family of new forgery attacks are described, which raise serious questions about the effectiveness of certain countermeasures.
