“…Symmetric algorithms are classified into block and stream ciphers. Encryption of plaintext is done bit-by-bit in case of stream cipher [14] and a group of bits (i.e., 64 bits) is taken for encryption in block cipher as a unit. The block cipher algorithm is preferred to the stream cipher for faster computations.…”

Recent advancements in wireless technology have created an exponential rise in the number of connected devices leading to the internet of things (IoT) revolution. Large amounts of data are captured, processed and transmitted through the network by these embedded devices. Security of the transmitted data is a major area of concern in IoT networks. Numerous encryption algorithms have been proposed in these years to ensure security of transmitted data through the IoT network. Tiny encryption algorithm (TEA) is the most attractive among all, with its lower memory utilization and ease of implementation on both hardware and software scales. But one of the major issues of TEA and its numerous developed versions is the usage of the same key through all rounds of encryption, which yields a reduced security evident from the avalanche effect of the algorithm. Also, the encryption and decryption time for text is high, leading to lower efficiency in IoT networks with embedded devices. This paper proposes a novel tiny symmetric encryption algorithm (NTSA) which provides enhanced security for the transfer of text files through the IoT network by introducing additional key confusions dynamically for each round of encryption. Experiments are carried out to analyze the avalanche effect, encryption and decryption time of NTSA in an IoT network including embedded devices. The results show that the proposed NTSA algorithm is much more secure and efficient compared to state-of-the-art existing encryption algorithms.

As Internet security threats continue to evolve, in order to ensure information transmission security, various encrypts and decrypts have been used in channel coding and decoding of data communication. While cryptography requires a very high degree of apparent randomness, random sequences play an important role in cryptography. Both Cellular Automata (CA) and RC4 contain pseudorandom number generators and may have intrinsic properties, respectively. In this chapter, a 3D visualization model 3DVM is proposed to display spatial characteristics of the random sequences from CA or RC4 keystream. Key components of this model and core mechanism are described. Every module and their I/O parameters are discussed, respectively. A serial of logic function of CA is selected as examples to compare with some RC4 keystreams to show their intrinsic properties in three-dimensional space. Visual results are briefly analyzed to explore their intrinsic properties including similarity and difference. The results provide support to explore the RC4 algorithm by using 3D dimensional visualization tools to organize its interactive properties as visual maps.

Data encryption is the best way to provide secure communication. Even though a lot of encryption schemes are available, this paper proposes a simple, fast and secure encryption scheme. The method is suitable to encrypt smaller as well as for larger files. The approach includes two files: symmetric key file and message file, both of any format opted by the user. In this approach the hackers can't even crack which type of message file was it. So breaking cipher text becomes impossible in effect. The proposed symmetric encryption scheme has the following features over traditional schemes. First, the encryption and decryption uses the same algorithm, which is safe, simple and fast. Second, any type of file can be encrypted using this approach. Third, any type of key file can also be used according to the user's wish. In this paper, the performance is compared with the popular encryption algorithms, and the results prove that the proposed scheme is more robust and faster than traditional encryption schemes.
