| Abstract(in English) | This paper deals with black-box tracing. which enables a tracer to identify malicious subscribers from a pirated version of a decoder used as a black box in content distribution systems. In this paper, we propose a tracing algorithm which enables the Kurosawa-Desmedt's traitor tracing scheme to support black-box tracing even if the pirate decoder has more than one decryption keys. Moreover, the proposed tracing algorithm can be applied to the Boneh-Franklin's one with black-box tracing. To show the traceability of our scheme, we define a c-arbitrary pirate decoder, which contains c decryption keys, and show that the proposed tracing algorithm can correctly identify at least two of the traitors in a coalition from it. |
