Abstract:

In secret key cryptography, a single key is used for both encryption and decryption. It achieves privacy and confidentiality. In this, sender sends the cipher text by encrypting the plain text with a secret key and receiver decrypts the cipher text by using same secret key to generate original plain text. The secret key must be shared between two authorized users secretly to apply at both the ends for encrypting and decrypting. Major challenge of secret key cryptography is the key sharing i.e., distribution of secret key to the sender and the receiver. This paper discusses the symmetric key cr

Abstract:

It has been said that quantum cryptography in general offers a secure solution to the problem of key enhancement. This means that two parties who already share a small secret key, can use quantum protocols to establish a new large secret key. This large secret key can be arbitrarily long and is unbreakable. Thus, to date, the main contribution of quantum cryptography has been believed to be quantum key enhancement. This paper shows that quantum cryptography can do significantly more. The quantum protocol described here distributes an unbreakable secret key to the two parties by relying on publ

Abstract:

Cryptography is a science of creating a secret message and it is constantly developed. The development consists of attacking and defending the cryptography itself. Power analysis is one of many Side-Channel Analysis (SCA) attack techniques. Power analysis is an attacking technique that uses the information of a cryptographic hardware’s power consumption. Power analysis is carried on by utilizing side-channel information to a vulnerability in a cryptographic algorithm. Power analysis also uses a mathematical model to recover the secret key of the cryptographic device. This research uses d

Cryptanalysis is a new ID-based encryption scheme proposed by Meshram. I found a method for factor N, where N is the parameter proposed by Meshram.

Identity-based (ID-based) cryptography is very useful because it simplifies certificate management in public-key cryptocurrency. For the design of the Integrated File Level Cryptographic Access Control (IFLCAC) system, it makes file security much easier for the end-user.

Abstract:

Novel idea of hierarchical visual cryptography is stated in this paper. The key concept of hierarchical visual cryptography is based upon visual cryptography. Visual cryptography encrypts secret information into two pieces called as shares. These two shares are stacked together by logical XOR operation to reveal the original secret. Hierarchical visual cryptography encrypts the secret in various levels. The encryption in turn is expansionless. The original secret size is retained in the shares at all levels. In this paper secret is encrypted at two different levels. Four shares are generated o

Abstract:

In cryptography, key exchange security is essential. Because the message code can only be a message that is analyzed with a key offer that matches this message. Secret messages can be delivered through symmetric cryptographic algorithms with coded keys or with key exchange algorithms. One of the key exchange methods that has been developed is Diffie-Hellman Key-Exchange (DHKE). Diffie-Hellman is a simple method used to generate a key between two parties in order to communicate securely.

The McEliece algorithm uses binary Goppa code for encryption and decryption, offering high execution speed and resistance to various types of attacks.

Cryptography is an art and science of secure communication. Here the sender and receiver are guaranteed the security through encryption of their data, with the help of a common key.

The cryptographic systems which perform these tasks are designed to keep the key secret while assuming that the algorithm used for encryption and decryption is public. Thus key exchange is a very sensitive issue. In modern cryptographic algorithms this security is based on the mathematical complexity of the algorithm. But quantum computation is expec

Abstract:

AbstractThis paper contains a brief description of new approach regarding LSB steganography. The novelty of the method resides in the combination of LSB (Least Significant Bits) steganography with some primitives of the pixel-sieve/bit-sieve cryptographic method. In short, we propose to use two or more carrier images and the sieving algorithm, borrowed from the pixel sieve primitive, to determine which carrier image will receive the next set of bits of the secret message. While in classic LSB steganography the secret message must be encrypted prior to embed the information into the carrier ima

Abstract:

During the transmission over the Internet, protection of data and information is an important issue. Efficient cryptographic techniques are used for protection but everything depends on the encryption key and robustness of encryption algorithm. Threshold cryptography provides the development of reliable and strong encryption and key management machine which can reconstruct the message even in the case of destruction of some particular numbers of shares and at the opposite the data cannot be reconstructed unless an allowable set of shares are been gathered. The earlier techniques available in l

Abstract:

Sensor devices in the Wireless Sensor Network (WSN) are commonly subjected to various forms of attacks, such as flood attacks, eavesdropping attacks, etc. When an attacker compromises a sensor device, the sensor device's data contents become non-confidential and are grabbed by the attacker, putting the entire network at risk. As a result, to prevent key leaks in WSN networks, this paper proposes a Token with Secret and Public Keys Sharing (TSP-KS) algorithm. In the existence of attackers, cryptography is used to provide secure communication. A traditional public-key cryptosystem is appropriate

Abstract:

This paper analyzes the encryption and weaknesses of E. Álvarez cryptography. On the basis of this, a new chaotic cryptography based on ergodicity is presented. The control parameter and the initial condition of the chaotic system are chosen as a secret key. A bit chain is generated by iterating the chaotic map, and the location where a plaintext grouping appears in the chain is found. We then write down the number of iterations of the chaotic map as the ciphertext grouping. Several weaknesses of the E. Álvarez cryptography are avoided in the new scheme, and the security of the new scheme is i

Abstract:

This paper introduces a new method of securing image using cryptographic and steganographic techniques. The science of securing a data by encryption is Cryptography whereas the method of hiding secret messages in other messages is Steganography, so that the secret’s very existence is concealed. The term ‘Steganography’ describes the method of hiding cognitive content in another medium to avoid detection by the intruders. The proposed method uses cryptographic and steganographic techniques to encrypt the data as well as hide the encrypted data in another medium so the fact, th

Abstract:

The present-day society depends heavily on digital technology where it is used in many applications such as banking and e-commerce transactions, computer passwords, etc. Therefore, it is important to protect information when storing and sharing them. Cryptography is the study of secret writing which applies complex math rules to convert the original message into an incomprehensible form. Graph theory is applied in the field of cryptography as graphs can be simply converted into matrices There are two approaches of cryptography; symmetric cryptography and asymmetric cryptography.

Abstract:

Cloud computing is utility-based computing provides many benefits to its clients but security is one aspect which is delaying its adoptions. Security challenges include data security, network security and infrastructure security. Data security can be achieved using Cryptography. If we include location information in the encryption and decryption process then we can bind access to data with the location so that data can be accessed only from the specified locations. In this paper, we propose a method based on the symmetric cryptography, location-based cryptography and ciphertext policy –

Abstract:

The rapid development of data drives the need for security in the data transmission process, with the aim of preventing access by unwanted parties to view the contents of the data sent. In order to achieve an optimal level of security, one of the strategies used is the application of cryptography. Cryptography using the Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) algorithms separately has often been used to protect the security of messages, whether in the form of text or digital images. This research will utilize a combination of the AES and RSA algorithms. This merger a
