Types of computer connections The mode of connection of the computers in a network is called Topology. Our Computer Network and Communication Assignment help experts analyse the different type of topologies as following: In this type of computer topology there is a central node that extends a connection to each computer on the network.

All the computers are independently connected to the central node and if any communication breaks in between, they still operate without any problem. In this type of topology all the computers are connected to each other end to end in the form of a ring. The signal circulates through the network until it finds the required terminal. In case there is any discontinuity in communication all the computers will stop operating.

In this type of topology all the computers and network devices are connected to a single cable or backbone so that all the nodes receive the message at the same time. Types of Computer Network Our Computer Network and Communication Assignment help professionals define the type of computer networks as three broad categories: This type of network is used to serve small number people located in a limited geographical area.

This type of network interconnects the computer devices in an area larger than that of LAN. It covers an area of a few city blocks to the area of an entire city. This type of network is used to serve large number people located in a much larger geographical area. Our Computer Network and Communication Assignment help experts define it as a network formed without the use of wires or physical media to connect different computers to the server.

Common network devices Network devices perform the task that carries data through computer network. Our Computer Network and Communication Assignment help experts analyse the basic network devices that are used by users: It connects computers together in a simple topology network.

It is an electronic device that receives a signal and retransmits it at a higher level or higher power. Our Computer Network assignment help tutors define modem as a device that performs the function of modulation and demodulation that is transmitting the data to telephone lines as analogue signals and on receiving them converting back into digital signals.

It is a computer hardware component designed to allow computers to connect to the internet or network. According to our computer network assignment help experts, these are simple networking devices that make it possible to connect two dissimilar media types such as twisted pair with fibre optic cables.

It is a device which receives incoming data from multiple ports and transmits it to the specific output port to its intended destination. This is a network device which connects multiple networks so that they communicate.

Our computer networking assignment helpers go on to explain that it operates at the data link layer of the OSI model. It can interlink two of their ports together at very high speed. It forwards data packets between two computer networks. It is a part of computer system or network that is designed to block unauthorized access while permitting outward communication.

So our Computer Network and Communication Assignment help highlight that a firewall is a network security device that grants or rejects network access to traffic flows between an untrusted zone.

It sends a broadcast query requesting the necessary information from a DHCP server. Important concepts of Computer Networking Allassignmenthelp experts are highly qualified and well versed in the Networking concepts, and we always look forward to helping you in difficult topics given below: I currently am working as Software Development Engineer at Amazon.

I am mostly occupied by my work and I love to interact and help people and this is the reason what brigs me here. I am really interesting person to talk to and my technical skills can be used to hone Also, because of various teaching projects that I have done in past 11 years I have got a strong hold in Teaching has been an inspiration my life.

I have peer tutored starting from my school days at various skill levels. Whether it is an "A" student or an individual I also did the full academic load of the masters Battlefield commanders used a simple letter-replacement encryption schema to obscure messages sent to troops in faraway lands a hundred years ago.

Such messages needed to be meaningless to anyone intercepting the message on its way to the distant point but be easily decoded by the person of whom the message was intended. Back then these messages were considered mostly safe and cryptanalysis, the attempt to break the encryption; it was done by hand and took a longer period of time than the message was valid.

The messages were secured with cipher that could be broken by trying 26 combinations. If the Germany military made changes to the machine the number of possible combinations exploded to quintillion! It would have seemed that messages secured using this machine would be safe forever. The two problems plagued the system that still haunts encryption experts today unfortunately: If the Polish Cipher Bureau broke the Enigma encryption in the beginning of mechanical, the computerized if you will, the cipher breaking was seen.

Then computers take aim at the cipher-text to try to recover the key, the message contents, or both. Depending on the cipher used and the key strength, as some messages can be decoded in a matter of minutes or hours. The new ciphers are constantly being developed and evaluated to combat the ever-growing threat. It should also be noted that it took several minutes, which depending on the length of the message, to both encrypt and decrypt a message. Now a days the encryption and the decryption of messages happen in real-time.

We provide online help with cipher text assignment. Cipher text refers to the encryption of plain text that is used for data transfer over the networks. Encryption is the means that protects our invaluable information.

Encryption helps in protecting the data in transit over the network or on the world wide web from unwanted intruders accessing and changing it. Encryption functions by making use of a mathematical formula known as cipher and a key to convert the readable data that is the plain text into a form that others cannot understand or the cipher text.

The key makes the encrypted data unique. Only people possessing the same key and the mathematical formula or the cipher can understand this or decode the encryption. Keys are generally long sequence of numbers protected by passwords or biometric authentication. One of the best ways that the data can be protected over the mobile devices is by encrypting it.

There are three general methods of encrypting the data. Specific files can be encrypted. Some folders can be encrypted or the entire hard disk can be encrypted. Most of the operating systems support at least one encryption methods. Encryption of the entire hard disk also known as the full disk encryption is the safest way of encryption wherein we are not deciding upon what has to be encrypted and what has not to be encrypted.

If the encryption of the entire hard drive is not possible. Then those files and folders can be encrypted that contains sensitive information. Data is highly vulnerable if is in transit.

If any error exists in cryptography then this gives the leeway for the cipher text to be deciphered with or without the key. Cryptography is the art or science of arriving at the cipher text or cryptosystem that provides adequate information security.

Cryptography is concerned with the actual securing of the digital data. We gladly provide cryptanalysis assignment help. What differentiates us from the other service providers is the quality online help with cryptanalysis homework.

Cryptography deals with the arriving of the cipher text with the help of various mathematical algorithms which provides basic information system security.

Cryptography can be regarded as the establishment of large toolkit with the various techniques of securing data to be transferred over the network. We are pleased to showcase help with cryptanalysis assignment.

The art or science of decoding or breaking the coded text or the cipher text is referred to as the cryptanalysis. Cryptanalysis is also used in testing of the cryptographic techniques for their strengths in transferring the secure data over the world wide web. We gladly provide help with cryptography assignment.

In a nutshell the study of the design of the cipher text is known as the cryptography and the study of the mechanism of decoding or breaking the cipher text is known as the cryptanalysis.

Cryptography and cryptanalysis can be widely regarded as complimentary to each other. The primary aim of cryptography is to provide following four basic services: It is a service that keeps the information safe from the unwanted suspicious intruder over the internet. The confidentiality security service is also referred to as the secrecy or privacy.

Confidentiality can be attained by enormous means right from physical securing or encoding to use of complex mathematical algorithms for securing data. We gladly provide help with confidentiality assignment. Data Integrity Data integrity is a security service that refers to the accomplishment of any change in the data.

A data may be altered intentionally by a malicious intruder. Data integrity refers to the service which confirms whether the data is intact since when it was first created, modified or transferred over the network.

Data integrity can not in itself prevent the alteration of the data but it surely tells us whether the data has been modified or altered over a process.

They are Symmetric key encryption. The basis of difference between the above two cryptosystems is on the basis of the relationship between encryption and decryption key. If the same keys are used for encrypting and decrypting then this kind of cryptosystem is known as the symmetric cryptosystem.

The study of the symmetric cryptosystem is known as the symmetric cryptography. Symmetric cryptosystems are also known as the secret key cryptosystems. Some of the conspicuous examples of symmetric key encryption methods are as follows: We also provide online help with cryptography project. We provide quality cryptography assignment help well within the deadline. Our experts invariably have a masters or a PhD degree in their domain or the area of specialization.

Our assignments are not only adequate for the undergraduates and graduate students but also for working professionals. Students as well as the working professionals can easily take help from our experts whenever they have any doubt over the cryptography topic.

In the earlier days when the use of computer was at an incipient stage only symmetric key encryption was in extensive use. Even now the symmetric key encryption is being used extensively and chances are very feeble that it will ever fade away. There are certain advantages it offers over asymmetric key encryption. Some of the prominent features of the symmetric key encryption are as follows: We provide help with symmetric key homework.

Computernetworkhomeworkhelp receive online cryptography assignment help on a daily basis. What sets us stand apart from the crowd of service providers is our quality cryptography project help. Detriments of symmetric key cryptography. The secure key establishment mechanism should be at its place. That is before any communication to begin between the two parties both the sender and the receiver must agree upon the establishment of the secret key.

Second and the most important factor is the trust factor. Since the sender and the receiver are using the Decryption is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer are able to read and understand.

It could be used to describe a method of un-encrypting the data manually or with un-encrypting the data using the proper codes or keys. There are two types of decryption Symmetric decryption Asymmetric decryption Asymmetric decryption: Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely.

In start, a network user receives a public and private key pair from a certificate authority. Users use this key to encrypt message, they send it to the recipient. On the other side when the recipient gets the message, decrypt it with their private key that no one else should have access to.

In symmetric cryptography, the same key is used for both encryption and decryption. It is simpler approach in dealing with each message, less secure since the key must be communicated to and known at both sender and receiver locations. Symmetric key Decryption In this the encryption and decryption of text is done by a single key.

Any person that knows key to encryption or decryption can access the file and its contents. Algorithms used are fast and they are used to protect large and bulk data. Both keys can be calculated or identified with the help of one another. Whole process is inexpensive; it is the reason why it is more preferred. Encryption and decryption is too fast that there is no time delay.

Data authentication is present as one symmetric key is not solution to any other file as its symmetric key. Main drawback of data protection process is the loss of the symmetric key to any outsider except the parties being involved in the exchange of messages or data through symmetric key.

In cryptography, encryption is the process of encoding messages or information in such a way that third parties cannot read it, the only authorized parties can. The message or information referred to as plaintext is encrypted using an encryption algorithm in an encryption scheme,turning it into an unreadable ciphertext ibid.

It is usually done with the use of an encryption key that specifies how the message is to be encoded. The any adversary who can see ciphertext should not be able to determine anything about the original message. The authorized party is able to decode the ciphertext using a decryption algorithm, that usually requires a secret decryption key that adversaries do not have access to.

An encryption scheme usually needs a key-generation algorithm to randomly produce keys for technical reasons. Kinds of encryption Symmetric key encryption In Symmetric-key schemes, the encryption and decryption keys are the same. The communicating parties must agree on a secret key before they wish to communicate. Public key encryption In public-key encryption schemes, encryption key is published for anyone to use and encrypt messages.

It is only the receiving party has access to the decryption key and is capable of reading the encrypted messages. The Public-key encryption is a relatively recent invention: This was written in by Phil Zimmermann and was purchased by Symantec in Encryption Homework Help Why we are best? Our team has highly qualified tutors to help you with the most challenging assignments. With clear and accurate solutions, computernetworkhomeworkhelp.

Our Encryption assignment help tutors will provide you with detail explanation on how to complete the assignment on your own for learning purposes and for exam In cryptography, a key is a piece of information a parameter that determines the functional output of a cryptographic algorithm or cipher.

The algorithm would produce no useful result without a key. In encryption, key specifies the particular transformation of plaintext into ciphertext, during decryption. The Keys are also used in other cryptographic algorithms, like as digital signature schemes and message authentication codes.

Need for secrecy In designing security systems, it is wise to assume that the details of the cryptographic algorithm are already available to attacker. The history of cryptography provides evidence that it can be difficult to keep the details of a widely used algorithm secret see security through obscurity.

The security of encryption system in most cases relies on some key being kept secret. Trying to keep keys secret is one of the most difficult problems in practical cryptography; see key management. Attacker who obtains key by, as example, theft, the extortion, the dumpster diving and social engineering can recover original message from the encrypted data, issue signatures.

Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, the misuse, the modification, denial of a computer network and network-accessible resources. The Network security involves authorization of access to data in a network that is controlled by the network administrator.

Users choose and are assigned ID and password or other authenticating information that allows them access to information and programs within their authority. The Network security covers variety of computer networks, public as well as private, which are used in everyday jobs conducting transactions and communications among businesses, the government agencies as well as individuals. The Networks can be private, like as within a company, the others which might be open to public access.

The Network security is involved in organizations, the enterprises, other types of institutions. The Network security do as its title explains: It secures the network, also protecting and overseeing operations being done. Most simple and common way of protecting network resource is by assigning it a unique name and a corresponding password. Network security concepts Network security starts with authenticating, commonly with a username and a password.

Network security requires just one detail authenticating the user name that is the password it is sometimes termed one-factor authentication. Once authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users.

It is effective to prevent unauthorized access; component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over network.

The intrusion prevention system IPS and Anti-virus software help detect and inhibit the action of these malware.

Anomaly-based intrusion detection system may also monitor the network and traffic for network may be logged for audit purposes and for later high-level analysis.

Communication between the two hosts using a network may be encrypted to maintain privacy. Honeypots, essentially decoy network-accessible resources, which may be deployed in a network as surveillance and early-warning tools, the honey pots are not normally accessed for legitimate purposes.

The techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new exploitation techniques.
