Exhaustive Study

In recent days, increasing numbers of Internet and wireless network users have helped accelerate the need for encryption mechanisms and devices to protect user data sharing across an unsecured network. Data security, integrity, and verification may be used due to these features. In internet traffic encryption, symmetrical block chips play an essential role. Data Encryption Standard (DES) and Advanced Encryption Standard (AES) ensure privacy encryption underlying data protection standards. The DES and the AES provide information security. DES and AES have the distinction of being introduced in both hardware and applications. DES and AES hardware implementation has many advantages, such as increased performance and improved safety. This paper provides an exhaustive study of the implementation by DES and AES of field programming gate arrays (FPGAs) using both DES and AES. Since FPGAs can be defined as just one mission, computers are superior to them.

Knapsack Algorithm

A lot of data is misused without the data owner being aware of it. Software developers must ensure the security user data on their system. Due to the size of the market that houses data, the security of record databases must be of great concern. Cryptographic systems or data encryption can be used for data security. The Merkle-Hellman Knapsack algorithm is included in public-key cryptography because it uses different keys for the encryption and decryption processes. This algorithm belongs to the NP-complete algorithm which cannot be solved in polynomial order time. This algorithm has stages of key generation, encryption, and decryption. The results of this study secure database records from theft by storing records in the form of ciphertext/password. Ciphertext generated by algorithmic encryption has a larger size than plaintext.

Digital images that are personal and confidential are very vulnerable to wiretapping by irresponsible parties. Especially if distributed via the internet network such as on Facebook, WhatsApp and e-mail chat based applications. Images that are sent sometimes are often confidential images and must be maintained. In order to maintain the security of digital images can be done by utilizing cryptographic techniques. Cryptographic techniques can secure digital images by changing pixel values from digital images so as to produce different pixel values from the original image to be secured. This research will use AES 128 bit and Triple DES methods for encryption and decryption of digital images on client-server based applications. The results of the encryption AES algorithm will be re-encrypted with the Triple DES Algorithm so as to produce pixel values that are far different from the original pixel values.

<span lang="EN-US">Advanced Encryption Standard (AES) adopted by the National Institute of Standards and Technology (NIST) to replace existing Data Encryption Standard (DES), as the most widely used encryption algorithm in many security applications. Up to today, AES standard has key size variants of 128, 192, and 256-bit, where longer bit keys provide more secure ciphered text output. In the hardware perspective, bigger key size also means bigger area and small throughput. Some companies that employ ultra-high security in their systems may look for a key size bigger than 128-bit AES. In this paper, 128, 192 and 256-bit AES hardware are implemented and compared in terms of throughput and area. The target hardware used in this paper is Virtex XC5VLX50 FPGA from Xilinx. Total area and Throughput results are presented and graphically compared.</span>

Readable Format

Encryption is the process of converting the data from readable format into unreadable format with help of any mathematical expression or sometimes with the help of key. On the other hand decryption is the reverse process of encryption with help of same key used at encryption or with the help of some other key. The paper presents the different methodology used for encryption and decryption. Several methods presented in the literature are reviewed. The methods- Rivest-Shamir-Adlemen algorithm, Data Encryption Standard, Advanced Encryption Standard and three different Secure Hash Algorithm are reviewed and implemented using various FPGA devices. The power consumption, delay and area are analyzed and compared. From the analyses it is been found that the performance of AES and SHA3 are better when compared to other algorithms. These algorithms provide high security when compared to rest of the methods.

now a day’s VLSI is developing technology as predicted by Moors law which is drastically increasing as per demand one of that is data security for efficient processing so, data encryption and decryption are major play in security for this an advanced encryption standard is there which uses reconfigurable hardware process in this paper field programmable gate arrays (FPGAs) kit of Xilinx based platform in which spartan3E EDK kit is used. Here we analyze the speed of AES algorithm by using this EDK environment where obvious high speed is considerable and with power consumption and throughput exemptions. With micro blaze soft core processer we implement our algorithm of AES by using c coding we configure the hardware structure. EDK tool with one round operation is done and both area utilization and throughput are observed as we are familiar that when area reduces power consumption also reduces.

Encryption And Decryption

In this paper two methods are used, namely the vigenere cipher method and the RSA method. The vigenere cipher method is an example of a symmetric algorithm, while RSA is an example of an asymmetric algorithm. The combination of these two methods is called hybrid cryptography which has the advantage in terms of speed during the encryption process. Each process, which is encryption and decryption, is carried out twice, so that security can be ensured. In the process of forming the key used the RSA method. In the encryption process using public keys that have been generated before when the key is formed. This public key is used in sending data to the recipient of a secret message where this key is used for the data encryption process. The Secret key is kept and will be used during the decryption process. There is a system architecture that describes how clients and servers communicate with each other over the internet using the TCP protocol where the client here is an IoT device and the server is a server.

Cryptography is the science of maintaining data confidentiality, where the original text (plaintext) is encrypted using an encryption key to be ciphertext (text that has been encrypted). In this case cryptography secures data from a third party so that the third party cannot know the original contents of the data because the one who holds the key for encryption and decryption is only the sender and receiver. There are several cryptographic methods that are commonly used, one of which is DES or Data Encryption Standard. DES is included in the key-symmetric cryptography and is classified as a block cipher type

Encryption And Decryption

Substitution Box or S-Box had been generated using 4-bit Boolean Functions (BFs) for Encryption and Decryption Algorithm of Lucifer and Data Encryption Standard (DES) in late sixties and late seventies respectively. The S-Box of Advance Encryption Standard have also been generated using Irreducible Polynomials over Galois field GF(28) adding an additive constant in early twenty first century. In this paper Substitution Boxes have been generated from Irreducible or Reducible Polynomials over Galois field GF(pq). Binary Galois fields have been used to generate Substitution Boxes. Since the Galois Field Number or the Number generated from coefficients of a polynomial over a particular Binary Galois field (2q) is similar to log2q+1 bit BFs. So generation of log2q+1 bit S-Boxes is possible. Now if p = prime or non-prime number then generation of S-Boxes is possible using Galois field GF (pq ), where q = p-1.
