Abstract
ZHANG Xue-jun et al.presented two multi-oriented traitor tracing schemes with full collusion resistance.They asserted that it was computationally infeasible for any number of users to get a different key by collusion.Here,these two schemes were cryptographically analyzed and a concrete collusion attack method was proposed based on simple linear combination which three or more traitors can build more than one valid decryption key.Further,these traitors cannot be identified by using black box tracing method.The result show that neither of the two traitor tracing schemes accomplish the full collusion resistance because of their intrinsic flaws.
