An ECC-Based Traitor Tracing Scheme
Jian Wang · Computer Technology and Development · 2007
Traitor tracing schemes allow detection of at least one traitor when a group of colluders attempt to construct a pirate decoder and gain illegal access to content.Chor and Fiat proposed some schemes which divide the content into some sessions and each session key is encrypted under some keys.We consider the same scenario as Chor and Fiat and present an ECC-based traitor tracing scheme,that is good against coalitions of at most k corrupt users.ECC-based traitor tracing scheme is constructed with an error correcting code.It is open,deterministic and efficient which requires session length 8k logN and 2k keys each session.
