Abstract
En 中文
To share data securely, existing works use a public key and a private key for transmission. The secured data sharing along with user authentication is necessary for mobile devices. So, proper authorization is needed to access data owners' credential information from cloud computing. Therefore, the paper presents a novel framework for secured data sharing and user authentication. The security-based authorization in data transfer is taken significantly. Initially, DO and DU register to TA and then hashcode is generated using 2C-Cubehash for the login. After login, the data is encrypted by PWCC and then uploaded by the owner into the mobile cloud. Later, with an end-user request, the possessor and permitter verify the user and give PPK and smart contract to the enduser. Using the two PPK, the client downloads the data. The successful transaction in the blockchain is monitored by the proprietor by constructing UUI-MT. The proposed model resulted in 3123 ms processing time, 2941 ms latency, and 98.03% security level. With the proposed model, secured user-authenticated data sharing is achieved.
