Abstract
The use of quantum cryptography to secure open network has expanded significantly in recent decades. Because the network involves private and sensitive data, it has become an integral aspect of our lives, as well as a valuable source of data. As a result, strong cybersecurity for this data is critical. Furthermore, data security against various attacks is a crucial concern. The data transferred across the network has varying levels of privacy or data confidentiality that might be affected. Data security aims to protect transferred data from unapproved access. This thesis is about the security and privacy service, which is required to keep transferred data secured from a malicious user. Quantum cryptography is the security technology that is used to ensure the data secrecy.The presented techniques fundamental concept is to make use of the advantages of quantum cryptography, under the principles of quantum computing; to find the best combination between the recently proposed algorithms which improve the security in the presence of quantum computing bases. The proposed algorithm can be used to build a symmetric key schedule. The algorithm is a combination of classic and quantum cryptography. The system makes quantum gates change dynamically therefore the cipher-text states will be non-orthogonal and an eavesdropper cannot infer any data. The system is extremely quick since it just uses the bases of quantum mechanics. Statistical testing and security analyses have been performed, and its resistance to various sorts of cryptanalytic attacks has been confirmed.
