Secure Communication and Information Exchange using Authenticated Ciphertext Policy Attribute-Based Encryption in Mobile Ad-hoc Network

Abstract

MANETs are considered as suitable for commercial applications such as law enforcement, conference meeting, and sharing information in a student classroom and critical services such as military operations, disaster relief, and rescue operations. Meanwhile, in military operation especially in the battlefield in freely medium which naturally needs high mobility and flexibility. Thus, applying MANETs make these networks vulnerable to various types of attacks such aspacket eavesdropping, data disseminating, message replay, message modification, and especially privacy issue. In this paper, we propose a secure communication and information exchange in MANET with considering secure adhoc routing and secure information exchange. Regarding privacy issue or anonymity, we use a reliable asymmetric encryption which protecting user privacy by utilizing insensitive user attributes as user identity, CP-ABE (Ciphertext-Policy Attribute-Based Encryption) cryptographic scheme. We also design protocols to implement the proposed scheme for various battlefied scenarios in real evironment using embedded devices. Our experimental results showed that the additional of HMAC (Keyed-Hash Message Authentication Code) and AES (Advanced Encryption standard) schemes using processor 1.2GHz only take processing time about 4.452 ms, we can confirm that our approach by using CP-ABE with added HMAC and AES schemes make low overhead.

Secure Data Sensor In Environmental Monitoring System Using Attribute-Based Encryption With Revocation

“…the only user in revocation list can't read the data because his transmission will be rejected by the system. There are many method to protect the data [3] [6], where they analyzed the secure data with encryption. Make a palintext become a ciphertext with Ciphertext Policy Attribute-Based Encryption (CP-ABE).…”

“…Wireless Sensor Networks (WSNs) have many applications in the internet of things era. One of them is an application for environment monitoring [2] [3][4] [5]. The environmental monitoring system uses WSN technology to obtain information such as carbon dioxide, carbon monoxide, temperature, humidity, luminosity, and noise.…”

“…To protect the sensor data in the data center, there are so many methods from previous researchers in contexts of data security, for example, a system that performs an encryption for the sensor data with Ciphertext-Policy Attribute-Based Encryption with authentication using HMAC [3]. This method is the best to protect data from the user who did not have the access right.…”

“…It offers security and access control. CP-ABE (Ciphertext-Policy Attribute-Based Encryption) [3] is one of the variant of ABE algorithm. CP-ABE is an asymmetric encryption mechanism that provides features using the user attributes as rule of policy in the ciphertext.…”

“…In CP-ABE, the ciphertext will be decrypted if and only if the attribute set of user's private key appropriate with the rule policy in the ciphertext. CP-ABE is appropriate for most applications, like for data exchange over wireless medium [3].…”
