Abstract(in English) | ID based broadcast encryption scheme based on MSK-TT key setting(ID-BE-MSK) has several new advantages. For example, every receiver can be managed by their identity information and the system can continuously subscribe and revoke receivers, when the total number of receivers is bounded. On the other hand, the system requires many public keys and many operations which is proportional to a number of receivers. These many public keys and operations are required when the set of the receivers is changed. This property is one of the disadvantage of ID-BE-MSK. Based on this property, this paper presents new traitor tracing scheme with resistance against the collusion attack which uses the keys linear combination of the private keys. |
