Secure data sensor sharing on ubiquitous environmental health monitoring application

In internet of things (iot) era,the limitation storage on wireless sensor network (wsn) can be solved by synchronized data sensors from the gateway node to the data center server. data in the data center can be remotely accessed by the user at any time and anywhere from end user devices such as pcs,laptop pcs,and smart phones.,and data should be accessed securely. the only legitimated user can access the data sensor from an environmental health data center. cp-abe (ciphertext-policy attribute-based encryption) is becoming a robust cryptographic scheme solution to this issue. to enable a secure data sensor sharing and access on an environmental health data center,we propose a secure system model using cp-abe which ensures confidentiality,integrity,and user privacy features. experimental results prove that the implementation of cp-abe does not overload the system. © 2016 penerbit utm press. all rights reserved.
