Traitor Tracing for Stateful Pirate Decoders with Constant Ciphertext Rate.
Duong Hieu Phan.
Abstract: Stateful pirate decoders are history recording and abrupt pirate decoders. These decoders
can keep states between decryptions to detect whether they are being traced and are then
able to take some counter-actions against the tracing process, such as ``shutting down'' or erasing all
internal information. We propose the first constant ciphertext rate scheme which copes with such
pirate decoders. Our scheme moreover supports black-box public traceability.
