Abstract

Currently, cryptography plays a major role in various computer and technological applications. With the high number of internet users, the use of cryptography to provide information security has become a priority. Several applications such as e-mails, electronic banking, medical databases and e-commerce require the exchange of private information. While, if the connection is not secure, this sensitive information can be attacked. The best-known cryptographic systems rely on the generation of random numbers, which are fundamental in various cryptographic applications such as key generation and data encryption. In what follows, we want to use pseudo-random sequences generated by the middle square generator. In this work, it must be possible to estimate that the data produced has random characteristics, knowing that the algorithm used is deterministic. Overall, this paper focuses on the testing of pseudo-random sequences generated by the middle square generator and its use in data encryption.

Abstract

The development of communications and digital transmissions have pushed data encryption to grow quicklyto protect the information against any hacking or digital plagiarisms. Also, the matrix computation algorithmsdeveloped since the fifties exploit different types of structures more algebraically. In this work, we willpropose an encryption system based on the Vandermonde matrix, to secure the data in the form of images.Some orders will be advanced MatLab programming.
