Cloud computing technologies comprise various kinds of significant desirable constrains such as security, liability, government surveillance, telecommunications capacity, anonymity and privacy. The usage of cipher text technology is considered as a desired technique for performing the process of encryption in order to solve the issue of granting security to the data that are shared in the cloud. Similarly, the architecture of multi-tenant in the cloud computing system grants benefits to both the service providers and end-users which shares a common cloud platform to multiple tenants (i.e.) users and suitable resources are also computed by implementing proposed architecture. Therefore in this research work, the concept of cipher text multi-tenant are integrated for providing enhanced security to the data shared in the cloud environment. Hence a Modified Elliptic Curve Cryptography (MECC) based on Diffee Hellman algorithm is proposed in this research paper which provides enhanced security using alternate key generation. The encryption, decryption, upload and download time are calculated and it is concluded that the algorithm that is proposed in this research paper consumes less time for all these measures when comparing with other existing algorithms. Characteristics like less memory, high operational performance, small sized keys and rapid key generation process, and effective resource savings enable the modified ECC to obtain high efficiency. The encryption time of the proposed MECC system was 51ms with the key length 4096 bits, whereas existing method had 92ms as encryption time. Likewise With the key length of 4096 bits, the decryption time for the proposed model was 159ms. Accordingly the proposed system has reduced cipher text key size of 836KB when compared with the existing AES, Blow Fish, and Two Fish. Additionally, the key generation time (35 s) also seems to be considerably reduced when compared with the existing methods. These statements reveal that the proposed system outshine the state of art methods in terms of key generation time, encryption and decryption time and computational complexity.

Blockchain system has various advantages in transaction data storage. Due to the distributed nature of blockchain, security becomes a concern to store private data. In literature, many techniques to maintain security in the blockchain is proposed. But the conventional data security schemes are not alone sufficient to incorporate complete security in blockchain. Hence in this paper, a blockchain management system with three layers of security is proposed. The proposed blockchain system is suggested for E-health record (EHR). The proposed system includes three layers, and the first layer contains a user authentication wall, which is used to verify the user based on unique user id, password and usage pattern. A tri-factor mechanism is used to verify the usage pattern of the user. In the second layer, the EHR manager is used to verify the query based on policy. The policy contains 48 rules, which is used to analyse the query to grand or denied access. The final layer consists of lightweight 16-bit XOR cryptography used to store the data as cybertext. The proposed system is evaluated using three medical datasets, and its performances are evaluated based on turnaround time, tardiness, actual time delay and average actual time delay. The simulation performance of the proposed technique, that turnaround time is 55ms, tardiness is 150ms, and actualtime delay is 160ms. The encryption time of Data 1, Data 2 and Data 3 is 550ms, 50ms, and 1150ms, respectively. On the other hand, the proposed technique consumed time for decryption of Data 1, Data 2 and Data 3 is 1750ms, 65ms, and 1450ms, respectively. The performance analysis proves the effectiveness of the proposed system. Ultimately, the proposed blockchain management system is more suitable for enhancing the security for handling health records.
