Secure quantum communication

The ever-expanding growth of computer networks, especially the Internet, has led to widespread changes in the way of life, work and activity of individuals, organizations and institutions. Therefore, information security is one of the essential issues in this cycle. By linking the internal network of organizations to the global network, the data of organizations becomes accessible to external individuals and hosts. Ensuring that unauthorized persons have access to sensitive information is one of the most important security challenges regarding the distribution of information on the Internet.

Various solutions have been offered such as restricting internet use, data encryption and using security tools for internal hosts and establishing internal network security. One of the most common ways to protect information is to encrypt it. Unauthorized access to encrypted information is not possible and only those with a password key are able to encrypt and use the information.

Encryption is information based on cryptographic sciences. The use of cryptography has a long and historic history. Before the information age, most users of information encryption were governments and especially military users. Most computer encryption methods and models are nowadays used. Detecting information that is typically stored on a computer and lacks any scientific cryptographic methods will be easily and without special expertise. Therefore, data encryption has evolved according to recent developments and new algorithms have been designed for this purpose. Unlike classical cryptography, which is used today to send secure data and whose security depends on the difficulty of solving mathematical problems such as breaking it down to very large prime numbers, most quantum cryptographic schemes keep the cryptographic keys separate from the data.
