With the goal to thwart known attacks on the conceptual public key
encryption scheme Polly Cracker, Ly constructed the Polly Two
encryption scheme. The set-up of this new asymmetric encryption
scheme is more sophisticated than that of Polly Cracker, and the new
proposal seems to fix several known problems.
The talk considers a heuristic attack on Polly Two, that aims at
recovering the plaintext from a given ciphertext without revealing
the secret key. The discussed approach in particular allows to solve the
most recent "Polly Two challenge".
