Introduction
Over the years, cryptography has been used to protect secrets, in a military capacity to make sure that either hackers, enemies of the countries, do not intercept sensitive formation. Ciphers, and encryption blocks are becoming so hard to break even the best super computers cannot break the codes in a timely fashion. Encryption has been improved over the years, also has been around for thousands of years and this paper is intended to explain about different forms of cryptography that either has been used or is still in use to this day. This paper is about

When coming to creating these types of security is predominately affiliated with the military, federal agencies, governments and so forth. When talking about computer security cryptography this started back in the 60?s and this came from a huge demand for the civilian sector to protect critical information and to transform data into a digital form. Years later in the 70?s IBM took up the contract and started to create an encryption system for communication systems, and that was known as DES (Digital Encryption Standard). Now with that being said let 's discuss about identification/ entity authentication technique. There are differences between identification and entity authentication, states about weak, strong and zero knowledge-based authentication. Entity authentication procedure is in ?actual time? procedure in the sense that provides a guarantee that the parties that are involved in carrying out some of the action of validation is functioning at the time of protocol execution. When passwords come to entity authentication would be considered a weak authentication. When coming to conventional password schemes that involve time natural outlines, which involved so-called weak authentication general is between 6 to 10 characters and is a dictionary word. According to this passage ?Conventional password schemes involve time-invariant passwords, which provide so-called weak authentication. (Menezes & Oorschot & Vanstone, 1996) Now, when coming to
In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into
M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information
During World War 2 was a time of devastation. It was also a great time of innovation. One of the greatest innovations was the beginning of modern computing. During World War 2 encryption was each army’s main way of keeping war plans secure. One of the most famous encrypting machines was named the Enigma. The Enigma was a machine that took input from one side; encrypts it and sends the message to another operator who then translates it using a code book (Gladwin). Using this machine, the German’s kept nearly all the information secure from other countries. To break these encryptions, the British secret service along with many other countries started to build machines that could defeat the Enigmas encryption (Gladwin). Soon after the Germans
Encryption is one of the most important technologies of cybersecurity designed to protect the confidentiality of data. Encryption uses a complex mathematical formula and a key which randomizes and creates a coded or encrypted message. Only the party that the message or data is originally intended for can read in plain text by using the appropriate key to decrypt the data. Some encryption algorithms such as AES (Advanced Encryption Standard) are very complex
During this time Richard has showed himself as a promising young specialist and researcher. His major specialization is Applied Mathematics and Computer Science, but as an exception for academic achievements, Alex was allowed by our faculty to write his projects and degree thesis in the field of Cryptography under Computer Security and Applied Algebra Department.
In the past decade, rapid advances have been made in the field of cryptography. These advances have brought considerable
As Paris tremble for fear from terrorist attacks that have killed 129 people, fierce blame for the massacre is falling on American whistleblower Edward Snowden and the spread of strong encryption catalyzed by his actions. The lastest deadly terror attack is leading the crypto-war as a contemporarily crucial issue. The crypto-war refers to a decades-long political battle over the legality and popularity of encryption around world. Since Snowden exposed the vast surveillance and spying done by Western governments, people have become to demand more strong encryption to shield their Internet activities from prying eyes, so encryption has been become popular rapidly. Now everyone uses encryption from e-commerce websites to terrorists. The key
The aim of this document is to provide an overview on the various cryptographic technologies in use today and what the future might hold. The document will cover the following subjects:
Communications Security is critical to preventing adversaries from obtaining information traversing the internet. With today’s technology just about all information is being transmitted via the internet or phone lines or mobile radios. This can be anything from credit card payments for online purchases to classified secret level or above information for military operations. The technology involved in the area evolving crypto systems such as KG-175s, emissions security or TEMPEST requirements protecting emanations, physical security like ensuring material is accounted for, and transmissions security or protecting information from interception. To support the ever growing technology there is specific equipment and storage requirements for network traffic and voice traffic. There is even equipment devised just to manage and account for the encryption devices on the network. The companies and organizations overseeing communications security include the National Security Agency, General Dynamics, and the Committee on National Security Systems. Finally there are global implications for communications security. National Security Agency surveillance and cyber attacks are among the most relevant concerns in today’s communications security. First discussed will be the technology involved in the area.
Transmission of data from one place to another securely becomes a challenging issue in this highly technological era. Stealing the information becomes the full-time job of hackers. To send the data secretly, encryption algorithms are used. Many encryption techniques are evolving to protect the information being send. In this essay, two different encryption methods, Quantum Key Description and Honey Encryption were explained briefly. Also, this essay addresses their benefits and limitations and the areas in which the algorithms are used.
During the World War 2, the need for secrecy pushed the allies and the axis to develop encryption technology in order to pass their messages safely. There were numerous devices developed during that period. The most famous are included in the following passage.
Encryption is a cryptography in which one covers data or information by transforming it into an undecipherable code. Encryption generally uses a predefined parameter or key to perform the data change. Some encryption computations oblige the best approach to be the same length as the message to be encoded yet other encryption counts can take a shot at much more diminutive keys concerning the message. Separating is as often as possible described close by encryption as it’s backwards. Unscrambling of encoded data realizes the first data. Encryption is used as a piece of customary forefront life. Encryption is most used among trades over flimsy channels of correspondence for instance the web. Encryption is also used to secure data being traded between contraptions, for instance, modified teller machines (ATMs), cells, and various more. Encryption can be used to make automated imprints, which allow a message to be affirmed. Exactly when honest to goodness executed, an automated imprint gives the recipient of a message inspiration to acknowledge the message was sent by the affirmed sender. Modernized imprints are outstandingly significant when sending tricky email and distinctive sorts of cutting edge correspondence. This is by and large equivalent to standard composed by hand marks, in that, an all the more astounding imprint passes on a more multifaceted methodology for manufacture. Figure a figure is an estimation, strategy, or method for performing encryption and translating.

Since the computer was invented the evolution of technology has grown into culture and has been the central of communication since the early 1980s. In order to understand the meaning of encryption and why it is so important, you have to understand why the computer was created and how inventors have continuously improved computer hardware devices. The computer was first invented to calculate numbers and help scientists with different mathematical equations. Then during the world war I, and world war II, Germans were using these computers to encrypt messages over morse code and complicated algorithms. However these algorithms of encryption were easily cracked by United States cryptographers. Over the war many encrypted messages were broken and the German military lost substations, overall control of the war; and eventually surrendering. Safe to say that encryption devices has been a necessity for transmitting data securely and in today’s society personal containment (Crayton & Culp, n.d.). Over the next five decades inventors, of all nationalities, have worked to improve encryption hardware devices from the internal architecture, removable storages, networking devices, and the overall networking security module.
With many companies allowing/requiring their employees to work and connect remotely, authentication plays a key role in the security of a corporation. With sensitive data being available outside of a localized network, it is important to verify the identity of connecting employees in a secure and encrypted way to prevent interception by attackers that would hope to gain by a lapse in security. There are different methods for which this authentication can be achieved. Some are more secure than others but all should involve the transfer of the sensitive login data being encrypted. This paper will discuss some of the differing methods that may be used in a remote login authentication system.
