  • Homomorphic Encryption Case Study

    1076 Words  | 5 Pages

    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

    person involve realize about it. This is why data encryption is important. Data encryption using asymmetric key is one of the most trustable data security algorithm. When the sender wants to send data or message, data encryption will change the data to an indecipherable state by using algorithms or theorems. Data encryptions are initially used by the authority military to communicate with each other during the old days. Nowadays, data encryption has become more recognized and people use it publicly

  • Why Is Data Storage Encryption Important

    about why data storage encryption is important. http://www.computerweekly.com/feature/Encryption-techniques-and-products-for-hardware-based-data-storage-security might help} Encryption is the process of encoding a message so that it can only be read by the sender and the intended recipient. When electronic data is encrypted it is converted into another form called cipher text, which cannot be easily understood by anyone except authorized parties. The main role of encryption is to be able to safely

  • Advantages And Disadvantages Of Cryptography

    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

  • The Art Of Steganography

    7033 Words  | 29 Pages

    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

    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

    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

    techniques. Thus it is proved that using cryptography techniques which use compression, hash function, automatic key generation, distortion process etc., the data becomes more secure and robust as compared to steganography technique alone. Thus the encryption of secret message and then hiding results in more secured

    message is called cipher text that is being sent by a sender to the receiver end along with many other DNA sequences. 3. PROPOSED ARCHITECTURE In order to provide better security in dada transmission scenario, a new method of encryption process is proposed here. This proposed encryption algorithm is works on the byte values of the message (plaintext). In this algorithm, byte values are extracted from the plaintext. These byte values are signed numbers (-128 to +127). In order to make those unsigned for

    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

    Overriding yes/no  Masquerade attack Over time biometric encryption is used as a solution to biometric security threat(Cavoukian & Stoianov, 2007),(Jain, Nandakumar, & Nagar, 2008). Biometric encryption is either symmetric or asymmetric. The process in which a single key is used for the purpose of encryption and decryption is known symmetric encryption. Whereas, asymmetric encryption involves the use of two different but related keys-the encryption key, and decryption key However, some Information Communication

    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

    lettered keyword. This cipher is a form of polyalphabetic substitution. In this cipher we make a key before encrypting the message so that it is a bit more secure. In this method the key shifts the alphabets according to its position. In this encryption the key needs to be known for the person decrypting it because there are about 26n possibilities where n is the number of letters in the string. For example let the code be: “mybirthdayisinjanuary” and let’s take the key to be “math” Plain Text

    We can judge the network to be secured if there are proper security measures implemented to protect the network. In order to be competent and secured, it is necessary to be aware of different security features. Some of the basic features/elements of security are: • Confidentiality • Integrity • Availability or Non-Repudiation These three put together are commonly known as “CIA” (Confidentiality, Integrity, and Authenticity) in the domain of network security. Some of the benefits of CIA are mentioned

    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

    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
