What is AES? AES is an encryption standard chosen by the National Institute of Standards and Technology(NIST), USA to protect classified information. It has been accepted world wide as a desirable algorithm to encrypt sensitive data. It is a block cipher which operates on block size of 128 bits for both encrypting as well as decrypting. Each Round performs same operations Strong encryption standards. Government agencies and private and public organizations around the globe use the industry standard for encryption: the Advanced Encryption Standard (AES)-256. AES replaced the older Data Encryption Standard (DES), which had become vulnerable to brute force attacks, which occur when an attacker tries multiple combinations of a cipher until one of them works. The. AES, also known by its original name Rijndael, was selected by the NIST in 2000 to find a successor for the dated Data Encryption Standard(DES). AES is a block cipher, that means encryption happens on fixed-length groups of bits. In our case the algorithm defines 128 bit blocks. AES supports key lengths of 128, 192 and 256 bit. Every block goes through many cycles of transformation rounds. I. To encrypt/decrypt data, the DES algorithm uses the Feistel structure. So, it uses some round to encrypt/decrypt data. Though data block size is 64 bit, the number of rounds will be 16 rounds. So.

The Data Encryption Standard (DES) is a symmetric-key block cipher derived from the Feistel model. It was published by the National Institute of Standards and Technology (NIST), and uses a 16-round Feistel structure operating on a block size of 64 bits. The key length for DES is 64 bits, but this is effectively reduced to 56 bits, as 8 of the 64 bits in the key aren't used by the encryption. Security: Encryption helps protect information from data breaches, whether the data is at rest or in transit. For example, even if a corporate-owned device is misplaced or stolen, the data stored on it will most likely be secure if the hard drive is properly encrypted. Encryption also helps protect data against malicious activities like man-in-the-middle attacks, and lets parties communicate.
