The "Elliptic" matrices and a new kind of cryptography

In [17], A. chillali et al introduce a new cryptographic method based on matrices over a finite field Fpn , where p is a prime number. In this paper, we will generate this method in a new group of square block matrices based on an elliptic curve, called "elliptic" matrices.

Information security with cryptography symmetric key encryption algorithms: a survey

In cryptography, data encryption turns ordinary information into an obfuscated code, and the information cannot be viewed without being decrypted. Thus, cryptography remains the main element of data protection. There are two kinds of cryptography, such as symmetric and asymmetric. There are many existing symmetric algorithms that are used to encrypt data, such as the Data Encryption Standard (DES), Triple Data Encryption Algorithm (TDEA), Enigmatic Diagonal Encryption Standard (EDES), Advanced Encryption Standard (AES), BLOWFISH, TWOFISH, Rivest Cipher 4 (RC4), Rivest Cipher 6 (RC6), which have been reviewed in this paper. It compares and tracks a summary of productive encryption calculations. The performance is compared with key size, space, time, security, and features of encryption methods.

Cryptography in Terms of Triangular Neutrosophic Numbers with Real Life Applications

In this article, our main focus is to put forward the concept of Cryptography in terms of triangular neutrosophic numbers. This kind of cryptography is really reliable, manual, secure, and based on few simple steps. All the encryption and decryption are easy to proceed (mention below). As we know, Public-key cryptography as an indefatigable defender for human privacy and use as information transfer from the ages. various concepts are available with regard to cryptography e.g. Elliptic curve cryptography. TNNC (Triangular neutrosophic numbers cryptography) is familiar with basic concepts of math as well as applicable in different situations e.g. code cryptography, detailed view cryptography, and Graph cryptography encryption facilitate.

A NEW KIND OF DIGITAL SIGNATURE SCHEME USING GOLDEN MATRICES BASED ON FACTORING PROBLEM

A.P. Stakhov in (12) proposed the concepts golden matrices and new kind of cryptography. In this paper, we propose a new kind of digital signature scheme based on factoring problem and the golden matrices, called the golden digital signature. The method is very fast and simple for technical realization and can be used for signature protection of digital signals (telecommunication and measurement system).

Electronic Voting Protocol Using Identity-Based Cryptography.

Electronic voting protocols proposed to date meet their properties based on Public Key Cryptography (PKC), which offers high flexibility through key agreement protocols and authentication mechanisms. However, when PKC is used, it is necessary to implement Certification Authority (CA) to provide certificates which bind public keys to entities and enable verification of such public key bindings. Consequently, the components of the protocol increase notably. An alternative is to use Identity-Based Encryption (IBE). With this kind of cryptography, it is possible to have all the benefits offered by PKC, without neither the need of certificates nor all the core components of a Public Key Infrastructure (PKI). Considering the aforementioned, in this paper we propose an electronic voting protocol, which meets the privacy and robustness properties by using bilinear maps.

Extended visual cryptography for continuous-tone images: effect of the optimum tone mapping

Visual cryptography is a kind of cryptography that can be decrypted only by a human visual system when stacking transparencies. Extended visual cryptography allows to print meaningful images on transparencies which can conceal the existence of 'secret' in the transparencies. Many studies have tried to incorporate continuous-tone images into extended visual cryptography. However, most of them failed in preserving the image quality after the encryption. This paper introduces a scheme for extended visual cryptography for continuous-tone images. The scheme is based on parallel error diffusion that can quickly encrypt images with no pixel expansion. The most important feature of this scheme is the optimum tone mapping so that the resulting images may have very high contrast comparing with the conventional schemes. Some experimental results are shown to evaluate the effectiveness of the optimum tone mapping.

A Secure Transmission Protocol for Wireless Body Sensor Networks

A wireless body sensor network (WBSN) is a typically wearable wireless network deployed on a user' body, which consists of biosensors and a local personal wireless hub, which we commonly call wireless body sensor network controller (WBSNC). The sensitive micro data (SMD) of WBSN users is collected by biosensors and forwarded to the WBSNC before it is delivered to the data process center (healthcare terminal or remote server) for further processing. Since SMD involves user's personal privacy, it is important to protect secure transmission of SMD. Therefore it is crucial to admit only legitimate biosensors and WBSNC into the network in a WBSN. Ensuring the safety of data transmission from each biosensor to WBSNC or between WBSNC and the data process center is essential because of the open feature in wireless channel. In this paper, we present a novel kind of cryptography and authentication method to assure a secure network admission and transmission in a WBSN based on ID. The procedures in this system to establish keys for each biosensor and WBSNC must offer high communication validity and as low energy consumption as possible. In addition, we also propose a new way to protect BSN secure access for biosensor and WBSNC in order to block interference from Pseudo Node.

New field of cryptography: DNA cryptography

DNA cryptography is a new born cryp- tographic field emerged with the research of DNA computing, in which DNA is used as information car- rier and the modern biological technology is used as implementation tool. The vast parallelism and ex- traordinary information density inherent in DNA molecules are explored for cryptographic purposes such as encryption, authentication, signature, and so on. In this paper, we briefly introduce the biological background of DNA cryptography and the principle of DNA computing, summarize the progress of DNA cryptographic research and several key problems, discuss the trend of DNA cryptography, and compare the status, security and application fields of DNA cryptography with those of traditional cryptography and quantum cryptography. It is pointed out that all the three kinds of cryptography have their own ad- vantages and disadvantages and complement each other in future practical application. The current main difficulties of DNA cryptography are the absence of effective secure theory and simple realizable method. The main goal of the research of DNA cryptography is exploring characteristics of DNA molecule and reac- tion, establishing corresponding theories, discovering possible development directions, searching for sim- ple methods of realizing DNA cryptography, and lay- ing the basis for future development.
