    threat. [16] It is an art of hiding the existence of communication, in contrast to cryptography. Basically it’s a method of concealing the information in ways that prevents the detection of hidden information. We should encrypt our information before communicating. By doing this, even if the message is being found, the intruder won’t be able to learn what we are trying

  • The Importance Of Cryptography

    1032 Words  | 5 Pages

    What is cryptography? Cryptography is the study of utilizing science to encode and unscramble information. Cryptography empowers you to store delicate data or transmit it crosswise over frail systems (like the Web) so it can't be perused by anybody aside from the expected beneficiary. While cryptography is the study of securing information, cryptanalysis is the study of examining and breaking secure correspondence. Established cryptanalysis includes a fascinating mix of systematic thinking, use

    needs to share some sensitive information in public networks, it becomes important that information does not go into wrong hands. Here, information security plays a major role. Sensitive information communication can be secured by using either cryptography or steganography. Steganography is a secret communication method for hiding data in some digital media such as images, audio etc. Hiding secret data using audio files as carrier is known as “Audio Steganography”. Moreover, MP3 files being more

    Cryptography is a technique or method to secure personal data from unauthorized 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

    Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure

    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

  • 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

    increasing day by day. Steganography plays a major role in secret data communication. It is nothing but to communicate in such a way that not only the contents are hidden but also the existence of message is kept secret which makes it different from cryptography which concerns only with keeping the contents secret. Steganography can be accomplished by hiding the information in other information, and for that, many different carrier file

  • Why Is Data Encryption Important

    1286 Words  | 6 Pages

    Attack on data always happens without the 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

    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

    Because Linux is only as secure as it is configured to be, the user must take many precautions to ensure that the server stays secure. Having very little or no security at all can pose a great problem for the system, network, and server, not to mention the company involved. If the server is not secure, the company can be in big trouble as private information can be leaked. Important data that should only been seen by certain employees can possibly be seen by all employees. This could cause a
