The present study would like to highlight in the application and utilization of the quantum cryptography for fully security to transmit the important data. In the classical cryptography system uses two key, there are public key and private key. The public key only known the receiver. But the key is shorter than the encrypted data. So it is too easy to attack. But the quantum key is with the same length as the encrypted data. So I generalized quantum cryptography system with the help of quantum key distribution , this is hypothetical approach.

These problems in one way easy to compute but in another way to computer reverse of it is very difficult without some perfect information. Classical Cryptography has two types
1. Symmetric Cryptography –In this cryptography only one secret key [1]is used in the case of encryption and decryption.
.
2.Asymmetric Cryptography-It is public key cryptography which consists of private and public keys in the case of encryption and decryption.
Deficiencies of Classical Cryptographical problems
As the key is shorter than encrypted data so all classical[2] cryptographic system can be broken. All the existing cryptographic systems would be easy to attack when one quantum computer was developed and they are become practically worthless .
A Quantum key Distribution system encodes information in single photons. It will solve the problem of cryptography key distribution in a provable secure manner, thus allowing secure

Transmission of photon are quantum in nature and take place on a quantum channel, Such as optical fibre. The conversation between Alice and Bob about the measurement types is made on classical channel, such as telephone or email .
Eve can intercept information transmitted on the classical channel without being detected. It is not a problem in Quantum Cryptography because in this protocol the information Alice and Bob exchange is the measurement type they made not result of the measurement and therefore nothing about the key that was developed.
Suppose Eve hears on a quantum channel. She may do this by reading some photons from the burst send from Alice to Bob. Now ,Eve has photon which are same in polarization with those received by Bob, and she randomly choose her own measurement type as she does not know what measurement type Bob is going to use. Assume Alice sends circularly polarized photon , which are received by Bob and Eve. Eve and Bob decide to use rectilinear and circular basses for measurement respectively. Here Alice and Bob record the resulting data as they both use same basis but Eve does not know there result since she used the wrong basis. Now Eve decided to use the circular basis and Bob the rectilinear basis to measure it, then Eve would have the same result that Alice sent and Bob would throw the
1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between
C1 then conducts a coin to randomize the order of which the two key bits are send to C2. C2 decrypts the two bits and evaluates which one is greater and informs C1. C1 then decides whether the condition is satisfied. During the execution of this protocol no information regarding the value of the two integers being compared is ever revealed to C2.
It is assumed that a transmission delay takes place at instant $t_k$, then the sampled data is used for observer at instants $t_k+
now if we use hash and because of its onewayness it is impossible to get back the password. If we use pure hash in the password and encrypt it, it can be broken easily by exhaustive search so that is why we have add some randomness to the password before the hash function is applied. The randomness is stored with the password hash. So now instead of pure hash and pure password we store the hash o/p of password chosen by me and some random number chosen by the system. From now whenever we use the password the system associates with the random number and gives access.
The experiment used a light of a single color, or monochromatic light, and two closely spaced slits or pinholes. He realized that the bright fringes of light resulted from light waves from both holes arriving crest to crest, creating a constructive interference. He also realized that the dark areas resulted from light waves coming from trough to crest, creating a destructive interference. The interference fringes made were straight lines. This interference experiment demonstrated the wave nature of light idea generated by Huygens 200 years earlier.
So in our Hybrid model - Strong, efficient and reliable personal messaging peer to peer architecture based on Hybrid RSA for an active networked environment, to tackle the Chosen cipher text attack when messaging is going on, Public Key Cryptography Standards (PKCS) version 5 is used. The basic RSA with Rabin-Miller strong Primality test with Efficient RSA with Euler Phi function variants integration and pohligHellmanEncipher with salt and padding integration makes it stronger and more reliable from the attacks like factorization of the RSA modulus n, message iteration attack, broadcast decryption by small exponent attack, broadcast decryption by common modulus attack, fault injection attack, the small difference between p and q attack and the finding eth root attack, Mathematical attacks and Timing attacks. Brute force attach is tackle by randomly changing the keys in synchronous time gap with 1024-bit value [13]. Also if somebody monitors pattern of the key so here as second layer and third layer reliable authentication between two parties key exchanging are there from the beginning. As in the instant messaging we generally cannot message for so long, so within these short time it’s quite impossible to do any brute force in our architecture with

Students will most likely need extra modeling and questioning to get them to this performance. They may be able to explain what steps they are taking with questioning and modeling.
A quienceañera is a tradition where girls transition to women. Quienceañeras are an important tradition to the Latino community because it signifies the person is growing up, will start being responsible, and enjoy a very special moment in life. The girl will grow up and have the attention for one night as if she was living a Cinderella story. She gets to be the person with the most wishes and gets celebrated for growing up to be a woman. Quienceañeras are one of the most well known traditions in the Latino community.
As per McWhinney model, Pairing of realities grouped in the Unitary and Sensory quadrants result in Analytic
For example, at the 1st station the ruler was slightly off balanced. This could have affected the results because we could have used inaccurate quantities when determining our answer. Another example would be the clips at the ends of the board in station 5. Since they jutted out slightly at the end it added some length to the board. This most likely affected the angle between the board and string.
A state is considered to be correct if no computation dependent on the mis-speculated data value has been performed in its predecessors. Computation which now restarted from a correct state can be guaranteed to be as correct.
A quinceanera is the celebration of a fifteen year old girl’s birthday that is celebrated in Hispanic cultures. This birthday is a very special birthday from all the other birthdays because it marks a girl’s transition from childhood to young adulthood. It is a social and religious event that emphasizes the importance of society and family in a young woman’s life. The celebration isn’t just about celebrating the girl for her maturity. It is also about celebrating the girl’s family as well as her godparents.
Communication is the process of transferring of information. Viswanathan (2010) says communication can take many forms of verbal and non-verbal methods which may include speaking, writing, gestures, expressions, listening and body language to name a few. All of these things should be taken into consideration to ensure an effective means of sending and receiving information. How and what information is sent may not be received in the same manner intended.
Quantum Computing: A Leap Forward in Processing Power We live in the information age, defined by the computers and technology that reign over modern society. Computer technology progresses rapidly every year, enabling modern day computers to process data using smaller and faster components than ever before. However, we are quickly approaching the limits of traditional computing technology. Typical computers process data with transistors.1 Transistors act as tiny switches in one of two definite states: ON or OFF.
Safety of our citizens is of utmost importance in creating a robust society. Building sustainable communities that are inclusive, secure and sensitive to needs of the citizens will continue to be of national priority. However, over the years, crime has stymied this endeavour. There must be a commitment to ensuring safety, security and justice for all citizens, which are seen as moral rights and intrinsic to development. Good policing, targeted social interventions and an efficient judicial system are needed to help our nation thrive.
