I want code for scalable and secured share of personal health record using attribute based encryption

Cloud computing is emerging paradigm provides various IT related services. The security and privacy are two major factors that inhibits the growth of cloud computing. Security factors are reasons behind lesser number of real times and business related cloud applications compared to consumer related cloud application. Firstly, the pros and cons of different Attribute Based encryption methods are analysed. Secondly, a new encryption method based on Attribute Based Encryption (ABE) using hash functions, digital signature and asymmetric encryptions scheme has been proposed. Our proposed algorithm is simplified yet efficient algorithm that can implemented for cloud critical application.
