Abstract :
We present attribute-based hash proof systems (ABHPS). Different from the HPS of the past, the witness is produced by the user´s attribute in the ABHPS. We also show how to construct a public-key encryption scheme which is semantically secure against adaptive chosen ciphertext attack in selective-set model using ABHPS. The scheme can be applied in cloud storage platforms for encrypted data. The user cannot obtain other useful information except for decrypting the ciphertext combine with his attribute.
