Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a Ciphertext-Policy Attribute-Based Encryption(CP-ABE) with traceability and revocability. By using our CP-ABE, anyone can trace at least one of the users who created the pirate decoder and revoke the traitor. We prove our CP-ABE is selectively secure for each part under the decisional Bilinear Diffie-Hellman exponent assumption and the modified decisional linear assumption.
