Abstract: For a data owner (patient) wants to share his health data, data which is extremely sensitive in nature and when he wishes to maintain privacy it is common for data owners to encrypt the data. Sharing encrypted data leads to difficulties in key management (traditional PKI infrastructure). In the first half of our work, we propose an novel attribute-based encryption, a further extension of identity-based encryption that allows roles or policies to be defined over a set of attributes and propose a hybrid attribute-based encryption - with revocation (H-ABE-R) which is more suitable for multi-user hospital settings as it allows us to give permissions to access data for short periods of time. We then propose a time and attribute-based keyword search (T- ABKS). We check our algorithm and prove our scheme comparably efficient.
