A Trade-off Traitor Tracing Scheme
There has been a wide-ranging discussion on the issue of content copyright protection in digital content distribution systems. Fiat and Tassa proposed the framework of dynamic traitor tracing. Their framework requires dynamic computation transactions according to the real-time responses of the pirate, and it presumes real-time observation of content redistribution. Therefore, it cannot be simpl...
متن کاملA Fully Public-Key Traitor-Tracing Scheme
We propose a fully public-key traitor-tracing scheme in which each subscriber can choose his or her own private decryption key without others learning the key. The distributor of the digital content utilizes the public data coming from all subscribers to compute a public encryption key. The paid contents are then transmitted to the subscribers, after being encrypted with the public key. Each su...
متن کاملAn Attack on A Traitor Tracing Scheme
In Crypto’99, Boneh and Franklin proposed a public key traitor tracing scheme [1], which was believed to be able to catch all traitors while not accusing any innocent users (i.e., full-tracing and errorfree). Assuming that Decision Diffie-Hellman problem is unsolvable in Gq, Boneh and Franklin proved that a decoder cannot distinguish valid ciphertexts from invalid ones that are used for tracing...
متن کاملA Lattice-Based Traitor Tracing Scheme
A traitor tracing scheme is a multi-receiver encryption scheme where malicious receiver coalitions aiming at building pirate decryption devices are deterred by the existence of a tracing algorithm: Using the pirate decryption device, the tracing algorithm can recover at least one member of the malicious coalition. All existing traitor tracing schemes rely either on rather inefficient generic co...
متن کاملAn Eecient Public Key Traitor Tracing Scheme
We construct a public key encryption scheme in which there is one public encryption key, but many private decryption keys. If some digital content (e.g., a music clip) is encrypted using the public key and distributed through a broadcast channel, then each legitimate user can decrypt using its own private key. Furthermore, if a coalition of users collude to create a new decryption key then ther...
