Secure Data Exchange Using Authenticated Attribute-Based Encdryption with Revocation for Environmental Monitoring

Abstract

Internet of things grown very rapidly, one of them is application smartcity for monitoring the environment. The environmental monitoring use the wireless sensor networks (WSN) technology to collect all of the data. All the data collected by the WSN will be sotred in the Data Center, where all of the data in the Data Center can be accessed by the user everytime and everywhere. The data center without security mechanism is very dangerous because all of data can be tracked and even modified by the users. There are need security mechanism for securing the data and monitoring access from each user. Chipertext Policy Attribute Based-Encryption (CP-ABE) with Authentication and Revocation can become a solution for this problem, where all of data in the data center can be protected with encryption and decryption mechanism. Its jut not protect the data, the security will give a guarantee for originality in the data and can give a control access for user who did the illegal access. The user who did the illegal access will be revoked by the system. Our security mechanism using the CP-ABE and timestamp digital signature using Rivest, Shamir Adleman (RSA) 2048 does not affect to performance of the system.
