| Abstract(in English) | Attribute-Based Encryption(ABE) allows only entities having a specified set of attributes can decrypt ciphertexts. ABE is applicable to access control such as the file sharing systems, because multiple entities can be granted for the decryption of a ciphertext. We propose an improved ABE scheme that is more efficient than previous one and give a proof of the chosen plaintext security under the standard model. |
