Abstract

Since now -a-days security is the primary concern for any organization. This paper provides the network security with the help of quantum cryptography and biometric. We use the BB84 protocol and biometric to secure the network. In this proposed method we create secret key by the help of fingerprint and quantum cryptography. Thus proposed method can be most secure and also easily understandable.

Emerging Cryptographic Techniques

Jayant Mehra, Harwant Singh Arri, Dhiraj Kapila +6 more

The main focus of this paper is to find out the emerging and future scope of cryptography. Using the principles of quantum physics, quantum cryptography is a revolutionary technique that enables two parties to protect network communications. The theory of quantum cryptography and how this technology improves network security are the main topics of this research study. This article encapsulates the state of quantum encryption at present, practical application implementations of this expertise, and ultimately the future course that quantum cryptography will take. The ease of authentication via fingerprint, eye, voice, palm, and other biometrics is expressly stated by biometric cryptography. Biometric verification provides more security than would be comfortably provided by conventional cryptography-based confirmation. A rapidly developing field of technology is DNA cryptography, which uses DNA computing principles.

Security awareness is one of the most pressing topics in today's globe. The idea of cryptography is introduced when the subject is information security. Conventional cryptography-based security techniques rely on the presumption that keys are shared before secure connections. The most crucial factor to consider when integrating cryptographic operations into account when integrating cryptographic operations in with any system is the safe key management strategy required for sending and transferring a secret key between two entities The systems will be vulnerable to bugs and possibly fatal external assaults if the fundamental management methods are poor A method for securely encrypting data sent between parties is quantum cryptography. and spotting eavesdroppers trying to overhear the conversation. Quantum cryptography may be the solution to these issues a quantum cryptography application, Quantum Key Distribution (QKD), refers to the production of a cryptographic key with unconditional security assured by physical rules. Quantum cryptography is a kind of encryption. We examine the quantum key exchange protocol (BB84 protocol) in this study and the way that it significantly improves data transfer security when compared to standard encryption techniques. The main objective of quantum cryptography is to offer a trustworthy way to provide a secure method of communication between the intended peers only and to detect the Eavesdropper presence.

Quantum Cryptography: A Brief Review of the Recent Developments and Future Perspectives

Azeem Iqbal, Muhammad Junaid Aslam, Sahar Hafiza Nayab

Quantum Cryptography is a novel approach to make the information and network world more secure. Unlike classical cryptography, quantum cryptography ensures the security of communication because it is based on the laws of Quantum Mechanics; a branch of physics that deals with the fundamental behavior of matter and their energies to the levels of subatomic particles. These particles and their intrinsic properties such as photon polarization and entanglement allow us to develop an unbreakable system of cryptographic information. Conventionally, the security has been primarily concerned with the secured distribution of secret key carried over an insecure channel. However, in Quantum Cryptographic systems the transmission of secret key is done using aforementioned laws of nature through a secured quantum channel highly susceptible to intrusion detection. Consequently, the Quantum Key Distribution (QKD), in conjunction with protocols such as BB84 protocol has emerged as an ultimate modern secured communication system. This article concentrates on briefly reviewing quantum cryptography, some recent developments and reports of its vulnerabilities.

QUANTUM KEY DISTRIBUTION SCHEME: AN IMPROVEMENT BASED ON BB84 PROTOCOL

Kausik Saha

Cryptography is being introduced to secure data. Through Classical Cryptographic technique, we can encrypt our data and secure secret key also. But classical cryptography is based on mathematical techniques where reversing one-way function is possible with sufficient computing power and time. So, Quantum Cryptography is introduced to overcome those drawbacks of traditional classical cryptography. It is based on the values of quantum mechanics and photon. Scientists and researchers have brought up a new key distribution protocol based on Quantum Cryptography is called Quantum Key Distribution (QKD) Protocol. The first QKD protocol BB84 was introduced by Charles Bennett and Gilles Brassard in 1984. After that several QKD protocols have been created. In this paper we have improved BB84 Protocol by removing the drawbacks of the existing algorithm towards Eavesdropping which may not be detected or disclosing large portion of secret key. Steps of the existing BB84 algorithm along with the modified one is described in detail with example and pseudo code. Limitations of BB84 and comparative study of both the existing and the improved one based on their security has been made and described in this current work.

Development of Mechanism for Enhancing Data Security in Quantum Cryptography

Ajit Pal Singh, Nidhi Sharma

Nowadays security in communication is increasingly important to the network communication because many categories of data are required restriction on authorization of access, modify, delete and insert.Quantum cryptography is one of the solutions that use property of polarization to ensure that transmitted data is not tampered.The research paper provides the mechanism that enhances the data security in quantum cryptography during exchange of information.In first phase detailed explanation of Quantum key distribution's BB84 protocol is given.BB84 protocol is used as the basis for the mechanism.In next phase the proposed mechanism is explained.The proposed mechanism combines BB84 protocol at two levels, from sender to receiver and then from receiver to sender.Moreover, a logic circuit is used to combine the bits hence to reduce the probability of eavesdropping.The key obtained can be used to exchange the information securely further it can help in encryption and decryption of crucial data.Double level BB84 mechanism will help in information reconciliation as well as privacy amplification.In future the proposed mechanism will be very beneficial where unconditional security is required during key and other secret information exchange
