In recent days securing the data while transferring through electronic devices from one end to the other has became a challenging task to both sender and the receiver. During the transmission of private data over the electronic devices may be hacked some times by the hackers. The data can be secured by using the cryptographic concept. This paper is about how the data are protected while transferring the data from one electronics devices to another using the ECC algorithm. Cryptographic algorithms plays an important role in securing the data against malicious attacks. The main goal of cryptography is not only to secure data from being hacked or attacked also it can be used for authentication of users. There are two types of cryptographic algorithms namely Symmetric key cryptographic algorithms and Asymmetric key cryptographic algorithms. Symmetric key cryptographic algorithm uses the only one key for both encryption and decryption process, where as Asymmetric cryptographic algorithm uses two different keys for encrypting and decrypting the messages. The public key is made publicly available and can be used to encrypt messages. The private key is kept secret and can be used to decrypt the received messages. Nowadays, many electronic devices like electronic phones, tablets, personal computers are in the workplace for transferring the data. Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create privacy, integrity and confidentiality, faster, smaller, and more efficient cryptographic keys.

Symmetric Key Cryptography

Cryptography is an essential and effective method for securing information’s and data. Several symmetric and asymmetric key cryptographic algorithms are used for securing the data. Symmetric key cryptography uses the same key for both encryption and decryption. Asymmetric Key Cryptography also known as public key cryptography uses two different keys – a public key and a private key. The public key is used for encryption and the private key is used for decryption. In this paper, certain asymmetric key algorithms such as RSA, Rabin, Diffie-Hellman, ElGamal and Elliptical curve cryptosystem, their security aspects and the processes involved in design and implementation of these algorithms are examined.

The paper examines the efficiency of the application of CUDA technologies for the parallelization of the cryptographic algorithm with the public key. The speed of execution of several implementations of the algorithm is compared: sequential implementation on the CPU and two parallel implementations – on the CPU and GPU. A description of the public key algorithm is presented, as well as properties that allow it to be parallelized. The advantages and disadvantages of parallel implementations are analyzed. It is shown that each of them can be suitable for different scenarios. The software was developed and several numerical experiments were performed. The reliability of the obtained results of encryption and decryption is confirmed. To eliminate the influence of external factors at the time of execution the algorithm was tested ten times in a row and the average value was calculated. Acceleration coefficients for message encryption and decryption algorithms were estimated based on OpenMP and CUDA technology. The proposed approach focuses on the possibility of further optimization through the prospects of developing a multi-core architecture of computer systems and graphic processors.

Cryptographic Techniques

Cryptographic techniques are primarily divided into two categories and they are: Symmetric key type and Asymmetric key type. In Symmetric key cryptography, during the process of encryption and decryption, the same key will be used. This is a conventional method of Cryptography. This might cause some disadvantage and give way for attacks on the algorithm. So, for this reason, the next technique comes into play. In Asymmetric key cryptography, there is a usage of a pair of keys, one for the encryption process and another for decryption process. In this technique also, there is a slight disadvantage, since there is a possibility for attackers to guess the public key from the pair of keys, thereby posing a threat to the process to an extent. In this paper, we develop an algorithm with a simple yet efficient structure using Symmetric key cryptography that could possibly decrease the chance of attacks on the algorithm.

Data security and confidentiality is one of the most important aspects of information systems at the moment. One attempt to secure data such as by using cryptography. In this study developed a data security system by implementing the cryptography algorithm Rivest, Shamir Adleman (RSA) and Vigenere Cipher. The research was done by combining Rivest, Shamir Adleman (RSA) and Vigenere Cipher cryptographic algorithms to document file either word, excel, and pdf. This application includes the process of encryption and decryption of data, which is created by using PHP software and my SQL. Data encryption is done on the transmit side through RSA cryptographic calculations using the public key, then proceed with Vigenere Cipher algorithm which also uses public key. As for the stage of the decryption side received by using the Vigenere Cipher algorithm still use public key and then the RSA cryptographic algorithm using a private key. Test results show that the system can encrypt files, decrypt files and transmit files. Tests performed on the process of encryption and decryption of files with different file sizes, file size affects the process of encryption and decryption. The larger the file size the longer the process of encryption and decryption.

The main objective of the study conducted in this article is to introduce a new algorithm of encryption and decryption of a sensitive message after transforming it into a binary message. Our proposed encryption algorithm is based on the study of a particular graph constructed algebraically from the quadratic residues. We have exploited the Paley graph to introduce an abstract way of encryption of such message bit according to the other message bits by the intermidiate study of the neighborhood of a graph vertex. The strong regularity of the Paley graphs and the unknown behavior of the quadratic residues will play a very important role in the cryptanalysis part which allows to say that the brute force attack remains for the moment the only way to obtain the set of possible messages.

Discrete Sliding Mode Control

This paper is concerned with the design of an improved El-Gamal cryptosystem based on chaos synchronization. The El-Gamal cryptosystem is an asymmetric encryption algorithm that must use the public and private keys, respectively, in the encryption and decryption processes. However, in our design, the public key does not have to appear in the public channel. Therefore, this proposed improved El-Gamal cryptosystem becomes a symmetric-like encryption algorithm. First, a discrete sliding mode controller is proposed to ensure the synchronization of master and slave chaotic systems; next, a novel improved El-Gamal cryptosystem is presented. In the traditional El-Gamal cryptosystem, the public key is static and needs to be open which provides an opportunity to attack. However, in this improved design, due to the chaos synchronization, the public key becomes dynamic and does not appear in public channels. As a result, drawbacks of long cipher text and time-consuming calculation in the traditional El-Gamal cryptosystem are all removed. Finally, several performance tests and comparisons have shown the efficiency and security of the proposed algorithm.

The wireless sensor network is a large number of tiny nodes installed in insecure environment for monitoring, gathering and transferring data and are prone to security threats for its limited resources. In order to transmit the data and to protect from different attacks in the network, security is maintained. To achieve confidentiality, authenticity and authorization of data which secure the data from different attacks cryptographic algorithm were used. The number of keys used in the cryptographic algorithm determines the security of the data. Cryptographic algorithms are broadly classified into two types symmetric cryptography and asymmetric cryptography. In the symmetric key cryptographic algorithm, a secret key is shared in the network and in asymmetric key cryptographic algorithm two keys are used for data security. In wireless sensor network, symmetric key cryptography required more storage to store the key among all the nodes of the network and in asymmetric key cryptography more computation time is require for the data encryption and decryption. To avoid memory and computation overhead we proposed a hybrid cryptosystem to handle the security in the wireless sensor network. Initially shared key is exchanged among nodes using ECC which is a public key algorithm. Data is encrypted and decrypted using RC4 symmetric key algorithm. Various performance measures such as time taken for encryption and decryption process and memory needed for storing cipher text data. The proposed model shows faster encryption of data and takes less memory for key storage as compared to the traditional approach.

The idea of information security lead to the evolution of cryptography. In other words, cryptography is the science of keeping information secure. It involves encryption and decryption of messages. The core of cryptography lies in the keys involved in encryption and decryption and maintaining the secrecy of the keys. Another important factor is the key strength, i.e. the difficulty in breaking the key and retrieving the plain text. There are various cryptographic algorithms. In this project we use Elliptic Curve Cryptography (ECC) over Galois field. This system has been proven to be stronger than known algorithms like RSA, DSA, etc. Our aim is to build an efficient elliptic curve cryptosystem for secure transmission or exchange of confidential emails over a public network.
