Christopher Hilario Bryan F. De Guzman3, Jhinia B. Since the symmetric block cipher is well past its prime, many methods have been devised by hackers in order to crack the cipher and obtain the plaintext message, namely through brute force attacks.
In order to improve its security, the authors have made modifications to the standard bit size, wherein it is doubled from a size of bits to bits on the key structure and plaintext block. The size of various tables, functions, keys and swaps that are found throughout the process of the original DES are also subject to this doubling in size.
Henceforth, the Expanded Data Encryption Standard is twice as extensive as its predecessor. By increasing the overall size of the cipher, it will take much longer for an attacker to bypass the security through the use of brute force. This necessitate a need of an adequate and effective cryptographic algorithms to secure these kind of data transmissions from an unauthorized user revealing.
Cryptography covers a wide area of techniques, including those such as microdots, merging words with images, and other ingenious ways to hide information from being intercepted by outside parties. It is the process of converting messages from a comprehensive form into an incomprehensive one at one end and which reverses the process at the other end so that the message is unreadable by interceptors or eavesdropper without the secret knowledge.
Of the various ciphers, block ciphers are the type often used in data encryption. Each block is generally comprised of 64 bits or bits. Although there is one cipher that is part of the first few to be invented.
An example of a symmetric block cipher is the Data Encryption Standard DESwhich is one of the oldest symmetric key-algorithms. This algorithm was published for public comment in Marchafter undergoing Government review for acceptability as a Federal standard.
The publication of DES was fundamental in the public understanding of modern block cipher design. It operates by using bit blocks along with a bit key. Going through the process of DES, wherein there are 16 rounds to be processed, first you need to encrypt the plaintext or the message, second you need a key generator to change the key for every round.
Unfortunately, in DES was declared as not safe enough, mostly because of the small key size that was inadequate when the technology advancement is considered. By increasing the original bit blocks to an amount of bit blocks, along with raising the bit key to a bit key, it will improve the protection of the cipher against brute force attacks by increasing the amount of time needed to crack the cipher.
By applying cryptography into important exchanges of information, it prevents unscrupulous individuals from abusing the information they could receive.
One study related to cryptography states the following: Different encryption techniques are used to protect the confidential data from unauthorized use,  which is the essence of cryptography, and some of these cryptographic techniques fall into the category of being symmetric block ciphers.Figure 4(a) shows the encryption time of the enhanced encryption algorithm.
For and message spaces, no matter where the message is located, the encryption time is only around microseconds. The lines for both and message spaces overlap.
