In this section, we will describe the symmetric key cryptographic algorithm which was introduced in [1] and discuss its robustness. graph is a pair G = (V, A) where V is a set of vertices, and A …

May 2, 2024 · In this article, we will cover the techniques used in symmetric key cryptography, its applications, principles on which it works, its types and limitations as well as what type of …

Jan 29, 2021 · A Cartesian product graph (CPG) is used to propose new symmetric encryption schemes. On proposed encryption schemes, the ciphertexts of the plaintexts are sent to the …

3DES is simply three DES encryptions with two different keys, for an effective 112 bit key; or with three different keys, for an effective 168 bit key. Why not use highest strength possible? …

A suite of cryptographic algorithms that take a key and convert between plaintext and ciphertext Main components Plaintext space: set P of possible plaintexts Ciphertext space: set C of …

The key stream is generated from a long term key k, both in encryption and in decryption, based on an internal state st and a transition function F. They are called synchronous if the key …

Symmetric key and asymmetric key cryptography are two main branches of cryptography. In asymmetric key cryptography, the sender encrypts the me. sage using a key known as public …

In this paper, a new symmetric key cryptosystem which uses the graphical representation of English alphabet was proposed. This cryptosystem is easy to implement but before …

RSA Alice picks two large secret primes p and q. Alice computes N = p q. · Chooses an encryption exponent e which satisfies gcd(e, (p 1)(q 1)) = 1, − − = 3, 17, 65537. Alice’s public …

Symmetric-key algorithms require both the sender and the recipient of a message to have the same secret key. All early cryptographic systems required either the sender or the recipient to …
