ABSTRACT:
Attribute-based encryption has been a
promising encryption technology to secure personal health records (PHRs)
sharing in cloud computing. PHRs consist of the patient data often collected
from various sources including hospitals and general practice centres.
Different patients’ access policies have a common access subpolicy. In this
paper, we propose a novel attribute-based encryption scheme for fine-grained
and flexible access control to PHRs data in cloud computing. The scheme
generates shared information by the common access subpolicy which is based on
different patients’ access policies. Then the scheme combines the encryption of
PHRs from different patients. Therefore, both time consumption of encryption
and decryption can be reduced. Medical staff require varying levels of access
to PHRs. The proposed scheme can also support multi-privilege access control so
that medical staff can access the required level of information while
maximizing patient privacy. Through implementation and simulation, we demonstrate
that the proposed scheme is efficient in terms of time. Moreover, We prove the
security of the proposed scheme based on security of the ciphertext-policy
attribute-based encryption scheme.
