In most existing KP-ABE scheme, the ciphertext size grows linearly with the number of attributes embedded in ciphertext.  ...  Meanwhile, the ciphertext size is independent of the number of ciphertext attributes, and the number of bilinear pairing evaluations is reduced to a constant.  ...  Thus, this transformation provides us with monotonic KP-ABE schemes with constant-size ciphertexts by using identity-based broadcast encryption schemes with linearity property and constant ciphertext size  ...

Third, ciphertexts received by the end-user are constant sized and independent from the number of attributes used in the access policy which affords low communication and storage costs.  ...  In this paper, we design PU-ABE, a new variant of key policy attribute based encryption supporting efficient access policy update that captures attributes addition and revocation to access policies.  ...  ACKNOWLEDGEMENTS This research is supported by STRATUS (Security Technologies Returning Accountability, Trust and User-Centric Services in the Cloud), a project funded by the Ministry of Business, Innovation  ...
