- 題目
- Enhanced Secret Key Traitor Tracing Scheme Using Bilinear Mapping
- 概要
- Traitor tracing is one of the most important security requirements in
the design of a broadcast encryption system against piracy or illegally
re-distributing an intended content. In this talk I will introduce a new
secret key traitor tracing scheme using bilinear mapping, in which the size
of the enabling-block in a broadcasting message is independent of the number
of receivers. Due to key independence, authorized receivers acting as
colluded traitors cannot find a linear combination of their personal keys to
generate a pirate key different from their personal keys for avoiding
traitor tracing. Furthermore, the broadcast center cannot deny an intended
content later and any authorized receiver does not have the ability to
falsify an unintended content for framing the broadcast center. I will also
give formal analyses to show that the proposed scheme is not only
collusion-resistance but also falsification-free in the random oracle model.
多数ご参加くださいますようお願い申し上げます．
