Data encryption is the method of translating information into another form or code so that access to the data is defined to only those with the proper decryption key (or password). Encrypted data is also defined as ciphertext. It is one of the most popular and extensive forms of information security. Encryption is an approach to secure digital information, by scrambling it as it travels across the web, or scrambling it when the data is "at rest" or stored on the computers.This provides that only authorized users can decrypt (un-scramble) the data and use it. Encryption improves the privacy and ... Read More

Encryption is the phase of taking plain text, such as text message or email, and scrambling it into an unreadable structure known as “cipher text.” This helps secure the confidentiality of digital information either stored on computer systems or sent through a network like the internet. When the pre-determined recipient accesses the message, the data is translated back to its original form. This is known as decryption.Data encryption is the phase of transforming information from a readable format to a scrambled element of data. This is done to avoid prying eyes from reading confidential information in transit. Encryption can be ... Read More

There are various types of Cryptanalysis attack on AES which are as follows −Linear Cryptanalysis Attack − Linear cryptanalysis is based on discovering affine approximations to the element of a cipher. It tries to take benefit of high probability linear relationship that exist among inputs and outputs of a function block.In the approach of a block cipher, linear set of plain text pattern and linear set of ciphertext patterns are distinguished to linear set of key bits. The main objective of linear cryptanalysis is to find a relationship that is prove either significantly more or less than 50% of the ... Read More

Data encryption is the procedure of transforming information from a readable format to a scrambled element of information. This is completed to avoid prying eyes from reading confidential information in transit. Encryption can be used to documents, files, messages, or some different form of communication over a network.Encryption is a security approach where data is encoded and can only be accessed or decrypted by a user with the proper encryption key. Encrypted data is also called a ciphertext. It can appears scrambled or illegible to a person or entity accessing without permission.Data Encryption is used to check malicious or negligent ...

Decryption is the procedure of changing encrypted information into its original, decipherable format. The phase of decryption takes the ambiguous information that was originally received and interprets it into words and images that a human can understand.Decryption is an important component of cybersecurity processes, because encryption needed scrambling words and pictures to securely send them to a multiple user through the internet.The process of encrypting and decrypting information adds a more layer of defense, because hackers who acquire that data in motion will not be able to understand it. The original format is known as plaintext while the unreadable format ... Read More

Linear CryptanalysisLinear cryptanalysis is a general style of cryptanalysis based on discovering affine approximations to the element of a cipher. Attacks have been produced for block ciphers and stream ciphers. Linear cryptanalysis is one of the two most broadly used attacks on block ciphers and the other being differential cryptanalysis.Linear cryptanalysis is a strong cryptanalytic tool regarding cryptanalysis of block ciphers. When using linear cryptanalysis, an adversary attempt to discover a linear expression that approximates a non-linear function with a probability different than 1/2.When a best approximation, it includes a relation between the plaintext and ciphertext, is discovered, the adversary ...

SHASHA stands for Secure Hash Algorithm. The Secure Hash Algorithm (SHA) is a family of cryptographic hash functions produced by the U.S. National Institute of Standards and Technology (NIST).The SHA 1 can take some arbitrary message as an input which is 264 bits in length and make 160-bit long message digest. SHA is broadly used in applications including SSH, SSL, IPsec and S-MIME (Secure, Multi-purpose Mail Extension).MD5The Message Digest (MD5) is a universal hashing algorithm that was invented by Ron Rivest and is used in several Internet applications today. It is a cryptographic hash algorithm that can be used to ... Read More

Linear cryptanalysis is a known plaintext attack, in which the attacker studies probabilistic linear relations referred to as linear approximations among parity bits of the plaintext, the Ciphertext and the hidden key.In this approach, the attacker acquire high probability approximations for the parity bit of the hidden key by computing the parity bits of the known plaintexts and ciphertexts. By use of several approaches including the auxiliary technique, the attacker can extend the attack to discover extra bits of the secret key.Linear cryptanalysis together with differential cryptanalysis are the generally used attacks on block ciphers. The linear cryptanalysis technique was ... Read More

Differential cryptanalysis is a general model of cryptanalysis applicable generally to block ciphers, but it can also to stream ciphers and cryptographic hash functions. In the largest sense, it is the study of how differences in data input can influence the resultant difference at the output.The main objective of differential cryptanalysis is to view for statistical distributions and patterns in ciphertext to provide deduce details about the key used in the cipher.Differential cryptanalysis is a section of study in cryptography that compares the method differences in input associated to the differences in encrypted output. It can be used basically in ... Read More

There are various application of MD5 Algorithm are as follows −MD5 was produced to store one way hash of a password, and some document servers also supports pre-calculated MD5 checksum of a document so that the user can compare the checksum of the log in record to it.MD5 Algorithms are beneficial because it is simpler to compare and save these smaller hashes than save a large variable length text. It is a broadly used algorithm for one-way hashes used to check without necessarily providing the original value.UNIX systems need the MD5 Algorithm to save the passwords of the user in ... Read More
