The demand for using wireless paradigms for performing various information and communication operations has been exploded. The opportunistic networks is a special type of delay tolerant networks proposed to operate in an emergency manner to facilitate mobile connectivity between the nodes when there is no connectivity. These emergencies are caused either by human-made or natural disasters. Opportunistic Networks depend on mobile phones and other mobile devices that carry wireless technology. This paper is an attempt to expand the opportunistic network through the authentication nodes. We propose an NTRU algorithm for node authentication in opportunistic networks .NTRU algorithm is an asymmetric post-quantum cryptosystem. This algorithm is unbreakable and robust compared to RSA and ECC cryptosystem.

“…Min et al [16] proposed a NTRUSign algorithm of ductility attack methods: an attacker by active eavesdropping, after receiving a message with the signature of the legal cases, able to forge a multiple legal signature of the message; At the same time give a repair defects of ductility MYK-NTRUSign digital signature algorithm. [17] In this paper, we employed the MYK-NTRUSign signature algorithm [18] [19] in combination with symmetric encryption algorithm (AES) and hash techniques (e.g. MD5 or SHA) to construct our new mutual authentication and session key agreement protocol appropriate for wireless communications.…”

In this paper, we propose a new bidirectional authentication and key agreement protocol based on the MYK-NTRUSign signature algorithm. The AES encryption algorithm and hash techniques were adopted to build our protocol. To implement the mutual authentication and session key agreement, the proposed protocol includes two phases: namely initial phase and mutual authentication with key agreement phase. As the MYK-NTRUSign signature algorithm is applied, our protocol not only can overcome the security flaws of authentication protocols based on secret-key, but also support greater security attributes and lower computational complexity in comparison with currently well-known public key based wireless authentication schemes.

“…Then the original message can be computed by m = fq * a (mod q). [10] IV. THE PROPOSED METHOD In this method the sender and receiver agree upon four steps of scrambling to the sound, according to random arrays that will be generated and encrypted by the sender and sent to the receiver in a metadata file.…”

Abstract-Scrambling is widely used to protect the security of data files such as text, image, video or audio files; however, it is not the most efficient method to protect the security of the data files. This article uses NTRU public key cryptosystem to increase the robustness of scrambling of sound files. In this work, we convert the sound file into text, and then scramble it in the following way: first, we encrypt the header of the sound file then, scramble the data of the file after the header in three stages. In each stage we scramble the data of the sound file and keep the original order of data in an array then, the three arrays are encrypted by the sender and sent with the encrypted header to the receiver in one file, while the scrambled data of the sound file is sent to the receiver in another file. We have tested the proposed method on several sound files; the results show that the time of encryption and decryption is reduced to approximately one-third, or less, compared to encrypting the file using NTRU.
