    The advantage of Delay Tolerant Networks (DTNs) is providing protocols that take into consideration of communication needed for the under constraints of high delays, error rates, inconsistent link connections, and unreliable networks. It is more attractive in the era of ubiquitous connectivity even in the area with such constraints to carry packets from source to destination. As the consequence, there should be many adversaries who may involve themselves in the networks to illegally access the valuable data. In this paper, we propose a secure system in DTN by utilizing Ciphertext-Policy Attribute-Based Encryption (CP-ABE) for controlling access data stored in storage nodes and keeping secret message exchange during maintenance of the routing process. In our system, CP-ABE encrypts data or message so that able to be decrypted only by the authorized nodes whose have a match attribute policy specified in their secret key. Experimental results show that our system is sufficient practical where the time of encryption, decryption and HMAC is less than a second.
