Popis:	102 In this thesis, we adopt exclusive or (XOR) operation and homomorphic encryption on Device-to-Device (D2D) data transmission. By doing so, we can improve the transmission efficiency without decrypting the data from the cipher domain. Reliable Butterfly Network Construction (RBC) is an important issue as well. We modify the system model by taking propagation path loss and shadowing effect into consideration and choose appropriate relays to build a butterfly mesh network. According to the result, we use appropriate network coding to improve the transmission efficiency, use homomorphic encryption to maintain the security of data and use RBC to construct a reliable network. If the main network relays cannot work, in this way, we would have backup relays to continue the communication.
