Abstract :
In this paper, we present a new efficient traitor tracing scheme against anonymous attack of which the security is based on the inverse weil-pairing assumption and the decisional k-BDHI assumption. The proposed scheme enables broadcasting a header with smaller constant transmission size regardless of the number of colluders and is much more efficient with lower computation cost
