Quantum cryptography is a field of study that explores the use of quantum mechanics to create new cryptographic techniques that are more secure than traditional cryptography. With the advancement of quantum computing technology, the security of many commonly used encryption algorithms is at risk. Quantum cryptography offers a potential solution to this problem by providing a method for secure communication based on the principles of quantum mechanics. In this paper, we will provide an overview of the fundamental concepts of quantum mechanics, their relevance to cryptography, and the most widely used quantum cryptography protocol, Quantum Key Distribution. The paper also examines the security and limitations of Quantum Key Distribution. The paper concludes with a summary of findings and implications for the future of cryptography and information security.

In now a days, most of the communication takes place through Internet.Most of the users are used to transmit their information through insecure channels that are interconnected throughout world.Thus, security must be provided to achieve confidentiality, access control, integrity and authentication.To ensure all these services, various cryptography and steganography techniques like RSA, AES, MD5 and RC5 have been used.Even though, cryptanalysts reinforcing it using some mathematical computation and misused information.Currently, quantum computers have been used to increase the speed of computation and to provide more security for data.It exploits quantum mechanics to provide secure communication.Quantum cryptography (QC) technique has been used to share the key among the participants who wish to share the data.This paper discusses various cryptographic key distribution protocols and quantum mechanics.In this paper we proposed "Secure Node Signature Verification Algorithm"(SNSVA) based on Quantum cryptography technique that describes how authentication can be verified with network nodes.In addition, it explains an approach to improve the performance of cryptography technique.
