Abstract EN
Attribute-based encryption achieves fine-grained access control, especially in a cloud computing environment.
In a ciphertext-policy attribute-based encryption (CP-ABE) scheme, the ciphertexts are associated with the access policies, while the secret keys are determined by the attributes.
In recent years, people have tried to find more effective access structures to improve the efficiency of encryption systems.
This paper presents a ciphertext-policy attribute-based encryption scheme that supports arithmetic span programs.
On the composite-order bilinear group, the security of the scheme is proven by experimental sequence based on the combination of composite-order bilinear entropy expansion lemma and subgroup decision (SD) assumption.
And, it is an adaptively secure scheme with constant-size public parameters.
