A personal encryption key, or name, known only to the transmitter of the message and its intended receiver, is used to control the algorithm’s encryption of the data, thus yielding unique ciphertext that can be decrypted only by using the key. Since the late 1970s, two types of encryption have emerged. It uses only one secret key to encrypt plain data, and uses 128-, 192-, and 256-bit keys to process 128-bit data locks. This algorithm receives data and encrypts it using a password. The same password is used to decipher the data with a decryption algorithm (or the same encryption algorithm, in some cases). International Data Encryption Algorithm (IDEA): IDEA (International Data Encryption Algorithm) is an encryption algorithm developed at ETH in Zurich, Switzerland. It uses a block cipher with a 128 encryption algorithm. A procedure or ordered set of instructions that specifies precisely how plaintext data is transformed into encrypted data or ciphertext. The input to an encryption algorithms includes the plaintext data and a encryption key. Encryption keys are designed to be a one-off, unique algorithm used to encode and decode data. By using an encryption key, you can encrypt data and send it to a friend, who can use the same key (which you supply) to decrypt the information, turning it into readable data. Dec 17, 2018 · Data Security is not just data at rest encryption, it is a total operational program driven by strategies, managed by processes, operated through clear procedures, and monitored by audit process in order to protect information assets; encryption is one piece of data security strategy. Each triple encryption encrypts one block of 64 bits of data In each case the middle operation is the reverse of the first and last.This improves the strength of the algorithm when using Key option 2,and provides Backward Compatibility with DES with Keying option 3

## Jun 11, 2020 · Data encryption revolves around two essential elements: the algorithm and the key. The algorithm is the set of rules that determine how the encryption works. The Caesar cipher algorithm we used earlier in this article substitutes each letter with another letter that sits a fixed distance away from it in the alphabet.

It uses only one secret key to encrypt plain data, and uses 128-, 192-, and 256-bit keys to process 128-bit data locks. This algorithm receives data and encrypts it using a password. The same password is used to decipher the data with a decryption algorithm (or the same encryption algorithm, in some cases).

### Dec 11, 2016 · An encryption algorithm is a component for electronic data transport security. Actual mathematical steps are taken and enlisted when developing algorithms for encryption purposes, and varying block ciphers are used to encrypt electronic data or numbers.

Data Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure. Here is the block diagram of Data Encryption Standard. Fig1: DES Algorithm Block Diagram [Image Source: Cryptography and Network Security Principles and Practices 4 th Ed by William Stallings] Aug 21, 2018 · AES data encryption is a more mathematically efficient and elegant cryptographic algorithm, but its main strength rests in the option for various key lengths. AES allows you to choose a 128-bit, 192-bit or 256-bit key, making it exponentially stronger than the 56-bit key of DES. Data Encryption Standard (DES): The Data Encryption Standard (DES) is an outdated symmetric-key method of data encryption . International Data Encryption Algorithm (IDEA) is a type of cryptography as a block cipher algorithm designed by "Xuejia Lai" and "James L.Massey" of ETH-Zürich and was first published in the 1991 year. Then, the original algorithm went through a few modifications and finally named as International Data Encryption Algorithm (IDEA) as follows. A personal encryption key, or name, known only to the transmitter of the message and its intended receiver, is used to control the algorithm’s encryption of the data, thus yielding unique ciphertext that can be decrypted only by using the key.
