Advanced Encryption Standard Essays

The Plutus and ATO fraud cases involved tax fraud. Plutus is a payroll company that a criminal syndicate used to obtain $165 million that was meant to be paid as taxes. Plutus undertook to process the payrolls of legitimate companies. The money was taken from the clients and transferred to several subcontracted companies. These tier two companies made payments to the employees of the clients. The directors of these companies were recruited to appear as if they were running the companies although

The Voynich Manuscript: Hoax or History? Since the early fifteenth century, a famous case in the history of cryptography, the Voynich manuscript, has puzzled cryptographers and scientists all around the world. Professional and amateur cryptographers believe the encrypted 240-page novel is written in an ancient code. Others believe it is written in a language yet to be discovered but translators have disproved this theory because the writings do not follow linguistic rules (Gannon). Over hundreds

user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand. In the present era everyone needs fast processing and less space required to store results in computation process as well as security of information. There are many encryption algorithms in which some of these take more computation time, some

A. Encryption Concept Encryption is the process of using a formula called the cryptographic algorithm to translate plain text into an incomprehensible code and later convert it back to plain text [3]. The text relies mainly on the use of a numeric value, called the key, which is part of the encryption algorithm. B. Cloud Computing Concept Cloud computing has become part of users' lifestyles because sources such as data storage, and computer systems are accessible as needed through networks that

shown in Fig.1 which it uses a cover medium (It used to hold secret data inside), the secret message (the secret data that is to be sent), hiding method (It used to hide secret message inside carrier file and produce the result is Stego-file) and an Encryption algorithm (the procedure is to encrypt Stego-file). The result of the process is the Encrypted Stego file which is the encrypted digital image/video that has the secret message hidden inside. Encrypted Stego-file is sent to the receiver via communication

a form of encryption that exploited the technology of the twentieth century. He developed a piece of cryptographic machinery that was basically an electrical version of Alberti’s cipher disc. This invention that would become the most

key amid transmission. Any individual who catches or blocks the key in travel can later read, change, and fashion all data encoded or confirmed with that key. From DES to Skipper Midnight's Mystery Decoder Ring, the constant issue with customary encryption is key conveyance: how would you get the way to the beneficiary without somebody capturing it? Open key cryptography The issues of key dissemination are unraveled by open key cryptography, the idea of which was presented by Whitfield Diffie

Public key cryptography is an asymmetric method that use a pair of keys for encryption: a public key which is used to encrypt data, and private, or secret key is used to decryption. It requires that a person must have a pair of public key and private key. The public key is distributed in the open so that anyone wishing to communicate

A Survey of Different Steganography Techniques Abstract Steganography is defined as the study of invisible communication. It usually deals with the ways of hiding the existence of the communicated data in such a way that it remains confidential. It maintains secrecy between the two communicating parties. The main objectives of steganography are high capacity of the hidden data, perceptual transparency (invisibility), temper resistance, undetectability, computation complexity and robustness. It

What is Unicode SMS? The term “Unicode SMS” refers to text messages sent and received containing characters not included in the default GSM character set. GSM stands for Global System for Mobile Communications (originally “Groupe Spécial Mobile”), and the GSM character set is a collection of the 128 letters (A-Z), numbers (0-9) and symbols (i.e. @, ?, !, &, etc.) most commonly used in mobile communications. Because GSM was developed in Europe and uses 7-bit binary code, it has its limitations. For

Walmart is one of the biggest company in the United States. The company is worth nearly $260 billion, as well as having to managed more than 5,000 stores in 10 countries around the world and employed approximately 1.5 million workers. Unlike others, Walmart developed its purchasing power by eliminating the middlemen and building direct relationship with the suppliers. In addition, the company purchases the products in bulk directly from suppliers at a lower cost and then sell items in stores at

Without human factors, random passwords, system-selected passwords, and long passwords can be considered as secure as compared to passwords based on names, passwords selected by user, and long short passwords. In addition, the habit of forcing users to make changes to password frequently and requisition for users to have different passwords for different entries should be adequate in efforts to fighting unsecure access. However, human factor is an issue that cannot be ignored in the contemporary

The so-called fully homomorphic encryption is considered the Holy Grail of Cryptography. Addition and multiplication are the main building blocks of computers, and the ability to make calculations on encrypted data without decrypting it, would lead to a whole new level of security. So, a company, for example, could send an encrypted database to a cloud computing provider, which would work on that data without decrypting it. If a customer wanted then to perform a search on their personal database

4. Strong collision: given a message M1, it is not possible to find two distinct messages such that h (M1’) = h (M1). The probability of this collision is 2n/2. Hash function is used in message authentication which uses a secret code before hashing so that no one else can modify the message and hash and then can encrypt the message for confidentiality. There are several ways of applying hash for message authentication: 1. One is to apply hash to the message and encrypt it and decrypt it using the

In order to make the cloak invisible, Light from all directions travel through the object, rather than hitting it. Because of not being able to interact with light, the hidden

Effective password policy is needed to prevent the passwords from being guessed or cracked. The password policy covers the passwords of all types via passwords of users, systems, databases, applications, etc.., while the password policy can be enforced where they are used frequently and by users, it is difficult to enforce for the passwords used in application to application communication. This article talks about the challenges and possible solution to eliminate embedded passwords in application

1. Symmetric encryption the keys should be changed frequently. They are shared between two peers, keys should be known only by the two members using them. So confidentiality is extremely important to key exchange. In-band key exchange takes place in the existing and established communication channel. This is however not secured and subject to eavesdropping attacks. Out-of-band key exchange takes place outside the communication channel or pathway, such as a secondary channel through special secured
