Protecting sensitive data is crucial in the age of widespread data digitalization and cloud-based services. This paper proposes a unique hybrid encryption algorithm deployed and tested over the cloud platform. The algorithm is reinforced with the robust cryptographic combination of Advanced Encryption Standard (AES) and Rivest-Shamir–Adleman (RSA). By utilizing the inherent benefits of symmetric and asymmetric encryption, the algorithm aims to improve the efficiency and security of data at rest and data being transmitted in a cloud-based environment. When tested on varied-length files and large data, the proposed algorithm encrypts the data securely and quickly. Various attacks including brute force, cryptanalysis were performed in the deployed environment to test the efficiency and effectiveness of the algorithm. It is observed that the algorithm outperformed Diffie-Hellman algorithm in terms of speed of encryption and data security with a factor of 6%. The algorithm's robustness against different security risks and its flexibility in changing cloud situations through an extensive examination is proven. The results not only highlight the hybrid approach's efficacy but also support its possible use in practical applications, therefore launching a new wave of robust cloud-based data management systems.

Ontology is broadly applied in various fields for creating trust‐based data access control models. In the case of the medical field, utilizing ontology is highly recommended for securing the medical report and patient information. Here, ontology is integrated with the grid computing system for achieving better authentication and security in the healthcare system. Various ontology based data access control models are designed by different authors for achieving enhanced user authorization and security. Security is still found to be a major issue in the existing techniques. To overcome this issue, the proposed work developed a medical ontology with three tier secure access control. The proposed method is processed in three layers. In the first layer, job scheduling for user is achieved. Job scheduling is carried out by scheduler using a deadline priority based scheduling algorithm. Users are scheduled with a different job based on their priority level such as low, medium, and high. In the second layer, role based policy is developed for finding and eliminating the accessing of unauthorized users. The third layer is used for securing medical database. Medical database is secured from various through encrypting the data using XOR cryptography algorithm. The proposed architecture is validated using some of the metrics such as turnaround time, tardiness, actual time delay, and throughput. The turnaround time, tardiness, and actual‐time delay attains for the proposed architecture are 64.60, 4.90, and 1.52 seconds, respectively. Then, the throughput value reaches for 25 bits length of encryption is 0.88 Mbps. The simulation analysis reveals that the proposed architecture reduces the waiting time of users and improves medical data security.

This paper provides an enhanced technique for improving the security and protecting the privacy of the cloud computing users by encrypting the data before it reached to server’s storage. Encrypting means the process of converting information or data into unreadable language to prevent unauthorized access. This paper will propose a mobile application design, which will allow the user to encrypt and decrypt the data hence maintaining security and privacy. In the proposed system design, the AES Algorithm will handle the encryption of the data using a keyword which will be defined by the user during the creation of the account. The encryption keyword will be hashed by the system using MD5 Algorithm. The keys will remain in encrypted form, while they are on the server side. Both encrypted data, encryption and decryption keys will be saved on the server in secured form. The idea behind hashing the encryption keys is to protect the keys while they are stored on the server, therefore, any unauthorized access to the server will gain no advantages since every bit of data on the server is encrypted including the private keys. The proposed system design will participate by improving the security and privacy of the users by giving them the capability to encrypt and decrypt data in enhanced way using AES as a data encryption method and MD5 hash algorithm for encrypting the encryption keys.
