Abstract: Presently, usage of Cloud computing is increasing, due to internet availability most of Personal Health Record (PHR) owners outsourcing their records to the cloud, but it is untrusted, so a security mechanism needed in this paper proposing Dynamic Time-based encryption (DTBE), it derived from classic ABE. In the past, many researchers suggested different access controls for secure PHR. Still, most of the access control mechanisms introduce burden to the PHR owner while performing dynamic operations insertion, PHR user revocation, and when it updates, PHR users attribute list. Most of the ABE schemes have several limitations as it cannot efficiently handle adding or revoking users or identity attributes. It needs to keep multiple encrypted copies of the same key that incurs high computational costs. So, there is a need for a suitable access control mechanism that should support effective policies.
