===== Cryptanalysis =====

In the preproceedings version of the POET paper from FSE 2014, a simple ciphertext forgery attack by [Guo-Jean-Peyrin-Wang][(ref:caesar:cryptoeprint2014197)] was possible using a single known ciphertext/tag pair, under the condition that the message consists of at least 3 blocks. The attack was facitated by an incorrect formulation of POET in the preproceedings version, as was pointed out by Stefan Lucks in [[https://groups.google.com/forum/#!topic/crypto-competitions/4-WMB0RrBzw|this discussion]] on the Cryptographic Competitions group, and is no longer applicable to the CAESAR candidate POET.
