Abstract

The π-cipher is one of the candidates of the CAESAR competition. One of the advertised features of the π-cipher is tag second-preimage resistance: it should be hard to generate a message with a given tag, even for the legitimate key holder (insider attack). In this note, we show that the generalized birthday attack of Wagner gives a practical tag second-preimage attack against the π-cipher.
