Improvised Diffie Hellman Key Exchange Protocol
Abstract: Protecting exchange of data over an insecure network is very crucial to maintain confidentiality. Diffie- Hellman protocol is a fundamental key exchange method and has proved to be a secure mechanism to securely exchange the cryptographic keys. Ralph Markel developed this idea, which has got its name from Whitfield Diffie and Martin Hellman. In this protocol, the recipient and transmitter generate a standard secret key and then start talking to …

Encoding-Decoding Algorithm Using the Catalan Transform of Weighted Tribonacci Sequence
Abstract: In order to improve information security, this paper presents a unique algorithm for encoding and decoding messages utilizing the Catalan Transform of a Weighted Tribonacci Sequence. Utilizing the Catalan and Tribonacci sequences, the methodology combines the concepts of number theory and combinatorics to create an effective encryption and decryption process. First, an array is created by mapping each character in the plaintext message to its corresponding ASCII value. The ASCII-weighted …

Reconfigurable AES Based AEAD For Multi-Mode Operation with Lightweight Compatibility
Abstract: The proposal is for a lightweight, multi-mode, reconfigurable authenticated encryption system with associated data (AEADs) based on AES. It is challenging to effectively integrate different AEADs in hardware because each one has its own mode of operation and/or subfunctions, even though some major AEADs share several basic components (such as the XOR-Encryption-XOR (XEX) scheme, block chaining, and advanced encryption standard (AES). This paper proposes hardware that effectively combines the basic …

A Practical Iterative Side Channel Cube Attack on AES-128/256
Abstract: AbstractThe Side Channel Cube Attack (SCCA) is a kind of Algebraic Side Channel Attack(ASCA) consisting of theoretical and practical aspects. This paper presents a general framework for the SCCA (called an Iterative SCCA (ISCCA)) on block ciphers in which theoretical and practical aspects are explained and the requirements are listed. On the theoretical side, we use extraction of quadratic equations, recognition of iterated chosen plaintexts, and cube iteration to improve …

Homomorphic Encryption Property Algorithms
Abstract: The demand for privacy of digital data increased over the last decade. The new invention in cryptography world is Homomorphic Encryption (HE). HE enables operation on cipher text without knowing the plaintext and private key. When receiver decrypts the result of any operation, it is the same as if the receiver carried out the calculation on the plain text. HE has some specific property. There are two properties in homomorphic …

Security of AES-128 in Front of Brute Force Attack
Abstract: Advanced Encryption Standard (AES) is one of the best known and most widely used block ciphers. It has three versions, i.e., AES-128, AES-192, and AES-256 that vary in their key sizes 128, 192 and 256 bits and in their number of rounds 10, 12, and 14, respectively. Data security has been a major and challenging aspect in the modern era of information technology involving the internet and network applications. It …
