Secure Cloudlet-based eHealth Big Data System with Fine-Grained Access Control and Outsourcing Decryption from ABE
2018
International Journal of Network Security
Preserved Fulltext
In this paper we propose a Cloudlet-Based eHealth Big Data System with Outsourced Decryption (CBe-BDS-OD) to address the above challenges. ...
To accommodate mobile devices with limited resources, the computation power is borrowed from the cloudlet server securely. Security analysis demonstrates that our scheme is secure. ...

Even though CC is a great innovation in the aspect of computing with ease of access, it also has some drawbacks. With the increase of cloud usage, security issues are proportional to the increase. ...
In this survey, we provide a comprehensive security analysis of CC-enabled IoT and present state-of-the-art in the research area. ...
Various techniques have been proposed to overcome this problem, like fine-grained sharing and attribute-based encryption (ABE). ABE has weak security and high computation overhead in cloud data. ...
