“…In Key aggregate cryptosystem, several number of private keys are combined to produce one key which has powers of all keys combined which is used in decryption access rights of cipher text set and persisting encrypted files outside the set were remains classified. S. Kumari and A.R.N Kamal (9) have suggested an approach which Attribute Based Cryptography and bilinear mapping (BM-ABE) are used so that security of data and integrity is maintained in cloud so that data shared is secure. The key which is secret is made more secure using MAC verification.…”

Personal health record (PHR) is a patient’s personal health information where a patient can store and maintain his personal health details in a cloud server which is a third party. Therefore, security and sharing of personal health information is a concern from parties like cloud server and unauthorized users. It is very important for a patient to have full control on their personal PHRs, hence it is important that PHRs have to be encrypted before outsourcing them to cyber service provider. In this paper, analysis of various PHR schemes for encryption is compared and results are analyzed.

Personal Health Record (PHR) in cloud database is stored, manipulated, and shared with users for high value of health care. The challenge is privacy of sensitive personal information and protection of data. In this paper, the attribute entropy key along with signature cryptosystem is proposed to move the data’s stored in third party cloud server in a secure way. In the proposed work, the PHR data is taken as an input and an attribute is selected for which attribute key generated using KEK (Key Encryption Key) algorithm. To secure the generated key, entropy is calculated for PHR data. This key is used to encrypt the PHR data. Then signature based on support value is generated for the PHR data and it is stored with the encrypted data in the cloud. Now, when the users want to access data, decryption is allowed after verification of both generated private key and signature which basically is for data integrity. Once the verifications are successful, then the authorized users are granted permission to access data from the cloud. The results display that the suggested method performs better when compared with other existing methods on parameters like cipher text size, query processing time, communication cost, and decryption time.

Summary Providing security to the data that stored in personal health record (PHR) is an emerging and critical task in recent years. For this purpose, some of the encryption and key generation techniques are developed in the traditional works. But it has the drawbacks such as lacks in access control policies, reduced security, and ineffective. So this work implemented the efficient techniques, namely, elliptic curve Diffie‐Hellman for the secret key generation and identity attribute–based encryption for improving the security of the cloud data. Initially, the cloud user can request the patient's data to the PHR admin, and then they can generate the secret by using the elliptic curve Diffie‐Hellman algorithm. The key that used for encryption and decryption is generated by using the identity attribute–based encryption technique. Then, the access control is provided to the users based on their roles. The requested data are encrypted by applying the advanced encryption standard technique. After that, the elliptic curve digital signature algorithm is used to generate the digital signature for the encrypted data. Furthermore, it is verified with the user's digital signature; if it matches, the data can be accessed by the user with the help of advanced encryption standard decryption mechanism. Finally, the authenticated user can able to access the patient's data from PHR. In experiments, the performance of the proposed encryption and key generation technique is evaluated and compared with the existing techniques for proving the effectiveness of the implemented system.
