This document provides an introduction to quantum cryptography. It explains that quantum cryptography uses principles of quantum mechanics like quantum entanglement and the Heisenberg uncertainty principle to securely distribute encryption keys. It notes that quantum cryptography combines the concepts of one-time pads and quantum key distribution, using quantum mechanics to detect any attempts at eavesdropping. The document also briefly discusses the history of cryptography, how quantum key distribution works, advantages and disadvantages of quantum cryptography, and its future applications.
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical communication. For example, it is impossible to copy data encoded in a quantum state and the very act of reading data encoded in a quantum state changes the state. This is used to detect eavesdropping in quantum key distribution.

Digital Signature Recognition using RSA AlgorithmVinayak Raja
• OBJECTIVE: Basically, the idea behind digital signatures is the same as your handwritten signature. You use it to authenticate the fact that you promised something that you can't take back later. A digital signature doesn't involve signing something with a pen and paper then sending it over the Internet. But like a paper signature, it attaches the identity of the signer to a transaction.

An alloy is a mixture of metals, or a mixture of metal and another element. White metal alloys are those which are light-coloured and generally have a lead or tin base. These alloys are also known as Babbitt metal, or bearing metal, a term which is generally preferred over ‘white metals’. Babbitt metal can be one of several alloys used as a bearing surface in a plain bearing.
Quantum Computing: Welcome to the FutureVernBrownell
Vern Brownell, CEO at D-Wave Systems, shares his thoughts on Quantum Computing in this presentation, which he delivered at Compute Midwest in November 2014. He addresses big questions that include: What is a quantum computer? How do you build one? Why does it matter? What does the future hold for quantum computing?
This is an introduction to modern quantum mechanics – albeit for those already familiar with vector calculus and modern physics – based on my personal understanding of the subject that emphasizes the concepts from first principles. Nothing of this is new or even developed first hand but the content (or maybe its clarity) is original in the fact that it displays an abridged yet concise and straightforward mathematical development that provides for a solid foundation in the tools and techniques to better understand and have a good appreciation for the physics involved in quantum theory and in an atom!
Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. Ceramic bearings offer many advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more. Ceramic balls are also nonconductive. Ceramic bearings are available in all standard industry configurations such as, angular bearings, thrust bearing, pillow block bearing, needle bearings, and roller bearings.
A SURVEY ON QUANTUM KEY DISTRIBUTION PROTOCOLSijcsa
Quantum cryptography is based on quantum mechanics to guarantee secure communication. It allows two
parties to produce a shared random bit string known only to them. These random bits can be used as a key
to encrypt and decrypt messages. The most important and unique property of quantum cryptography is the
ability of the two communicating users to detect the presence of any third party trying to gain knowledge of
the key. It is based on fundamental aspects of quantum mechanics. By using quantum entanglement or
quantum super positions and transmitting information in quantum states, a communication system can be
implemented which detects eavesdropping. Quantum cryptography is used to produce and distribute a key,
not to transmit any message data. This key along with certain encryption algorithm, is used to encrypt (and
decrypt) a message, which can then be transmitted over a standard communication channel. This paper
concentrates on comparison between classical and quantum cryptography as well as survey on various
quantum key distribution protocols used to generate and distribute the key among communicating parties.

IMPROVING TLS SECURITY BY QUANTUM CRYPTOGRAPHYIJNSA Journal
Quantum Cryptography or Quantum Key Distribution (QKD) solves the key distribution problem by allowing the exchange of a cryptographic key between two remote parties with absolute security, guaranteed by the laws of quantum physics. Extensive studies have been undertaken on QKD since it was noted that quantum computers could break public key cryptosystems based on number theory. Actually, the progress of research in this field allows the implementation of QKD outside of laboratories. Efforts are made to exploit this technology in the existing communication networks and to improve the performance and reliability of the implemented technologies. Some research is in progress for the integration of QKD with the protocols in different layers of OSI model. The examples of such research effort are the integration of QKD in point-to-point protocol (PPP) OSI layer 2 and the integration of QKD with IPSEC at OSI layer-3. All these works are moving towards the utilization of QKD technology for enhancing the security of modern computing applications on the internet. In this paper, we present a
novel extension of the TLS protocol based on QKD. We introduce a scheme for integrating Quantum Cryptography in this protocol. Our approach improves the security of the process of authentication and data encryption. Also, we describe an example to illustrate the feasibility of our scheme’s implementation.
ANALYSIS OF THE SECURITY OF BB84 BY MODEL CHECKINGIJNSA Journal
Quantum Cryptography or Quantum key distribution (QKD) is a technique that allows the secure distribution of a bit string, used as key in cryptographic protocols. When it was noted that quantum computers could break public key cryptosystems based on number theory extensive studies have been undertaken on QKD. Based on quantum mechanics, QKD offers unconditionally secure communication. Now, the progress of research in this field allows the anticipation of QKD to be available outside of laboratories within the next few years. Efforts are made to improve the performance and reliability of the implemented technologies. But several challenges remain despite this big progress. The task of how to test the apparatuses of QKD For example did not yet receive enough attention. These devises become complex and demand a big verification effort. In this paper we are interested in an approach based on the technique of probabilistic model checking for studying quantum information. Precisely, we use the PRISM tool to analyze the security of BB84 protocol and we are focused on the specific security property
of eavesdropping detection. We show that this property is affected by the parameters of quantum channel and the power of eavesdropper.
Vampire attack a novel method for detecting vampire attacks in wireless ad –h...IJLT EMAS
Ad-hoc wireless networks are dynamic in nature. Adhoc
networks are not depends on any predefined infrastructure.
Whenever there is need of communication at that point these
network can be deployed. In this paper we discuss Vampire
attacks. All protocols susceptible for vampire attack. Vampire
attacks are very easy to carry out throughout the network and
difficult to detect. Wireless sensor networks (WSNs) are the
foremost promising research direction in sensing and pervasive
computing. Previous security work has focused totally on denial
of service at the routing or medium access management levels.
Earlier, the resource depletion attacks are thought about solely
as a routing drawback, very recently these are classified into new
category as “vampire attacks”. Planned work examines the
resource depletion attacks at the routing protocol layer that
disable networks permanently by quickly debilitating node’s
battery power.
Neural Cryptography for Secret Key ExchangeIJMTST Journal
The goal of any cryptography system is the exchange of information among the intended user without any leakage of information to other who may have unauthorized access to it. A common secret key could be created over a public channel accessible to any opponent. Neural networks can be used to generate common secret key. In case of neural cryptography, both the communicating networks receive an identical input vector, generate an output bit and are trained based on the output bit. The two networks and their weights vectors exhibit a new phenomenon, where the networks synchronize to a state with identical time-dependent weights. The generated secret key over a public channel is used for encryption and decryption of the message or information send over the channel.
Analyzing and Securing Data Transmission in Wireless Sensor Networks through ...ijtsrd
Wireless Sensor Networks are gaining popularity in various fields and areas. But these nodes are vulnerable as they are open networks and easily accessible. The major challenge is to have a secure data transmission between the nodes. To establish a secure transmission, we require a security scheme like a cryptographic algorithm, but this also requires a secure key distribution between nodes. The WSN’s have constraints like limited area, power and memory which restrict all the categories of cryptographic algorithm. Depending upon the criteria’s and constraints, cryptographic algorithm like Elliptic Curve Cryptography ECC is best suitable for WSN’s environment. ECC has a smaller key size, high security and less computation time which makes the node an efficient crypto system. In order to protect the security of data, we propose a novel secure transmission strategy based on Cryptography. In this design, we acquire sensitive information securely so as to make use of the advantage of encryption. Our approach deal with the weakness of limitation in sensor node resources and the security threats, it is suitable for stream data in sensor nodes. The simulation experiments also demonstrate that this approach is effective in transmitting sensitive data covertly with the characteristics of lower energy consumptions and invisibility. This paper describes the implementation of ECC cryptosystem for WSN for secure key and data transmission between the nodes.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

and Crypto analysis
4. INTRODUCTION
What is Quantum Cryptography?
Quantum Cryptography is an effort to allow two users of a
common communication channel to create a body of
shared and secret information.
This information, which generally takes the form of a
random string of bits, can then be used as a conventional
secret key for secure communication.
5. INTRODUCTION
What is Quantum Cryptography? Contd.
The Heisenberg Uncertainty principle, and quantum
entanglement can be exploited in as a system of secure
communication often referred to as “Quantum
Cryptography”.
6. INTRODUCTION
Quantum Entanglement:
Quantum entanglement is a physical phenomenon that
occurs when pairs or groups of particles are generated or
interact in ways such that the quantum state of each
particle cannot be described independently of the others,
even when the particles are separated by a large distance—
instead, a quantum state must be described for the system
as a whole.
8. HISTORY
4000 years ago, they used the concept of
SUBSTITUTION CIPHER with key for securing the
data.
9. Since 1970: PUBLIC KEY CRYPTOGRAPHY, exchange
of secret messages with a person who you never met
before
10. Now the present generation is using QUANTUM
CRYPTOGRAPHY for securing the information
without encrypting.
So, what is quantum cryptography??
11. QUANTUM CRYPTOGRAPHY
Although the field of cryptography is ancient, but it is
not static. Quantum cryptography is a relatively new
concept in cryptography.
Basically quantum cryptography is combination of
OTP and QKD.
Quantum cryptography is based on two important
principles –
Polarization of light.
Heisenberg’s uncertainty principle
12. RSA
The most widely used PKC is the RSA (Rivest –
shamir-Adleman) algorithm based on the
difficulty of factoring a product of two large
primes.

13. QUANTUM KEY DISTRIBUTION
Quantum key distribution (QKD) uses quantum
mechanics to guarantee secure communication.
Quantum Key Distribution tell us all attempts of
eavesdropping.
Quantum key distribution is only used to produce and
distribute a key, not to transmit any message data
It enables two parties to produce a shared random bit
string known only to them, which can be used as a
key for encryption and decryption
14. OTP (ONE TIME PAD)
One-time pad (OTP) is an encryption technique that
cannot be cracked if used correctly.
The key used in a one-time pad is called a secret key
15.
16.
17.
18. ADVANTAGES
Virtually un-hackable.
Simple to use.
Less resources needed to maintain it.
Used to detect eavesdropping in quantum key
distribution.
20. FUTURE SCOPE
The experiments suggests transmission to satellites is
possible, due to the lower atmospheric density at higher
altitudes.
The current commercial systems are aimed mainly at
governments and corporations with high security
requirements.
Factors preventing wide adoption of quantum
cryptography outside high security areas include the cost of
equipment, and the lack of a demonstrated threat to
existing key exchange protocols
21. CONCLUSION
• Quantum cryptography is a major achievement in
security engineering.
• As it gets implemented, it will allow perfectly secure
bank transactions, secret discussions for
government officials, and well-guarded trade secrets
for industry!
