    What is a single round of DES algorithm?
    Fig2: Single Round of DES Algorithm. [Image Source: Cryptography and Network Security Principles and Practices 4th Ed by William Stallings] Round i: In each round 64bit text divided into two 32bit parts. Left and Right. You can see in diagram L i-1 and R i-1. As algorithm says, Right 32bits goes under Expansion Permutation.

    Is Triple DES a secure cipher?
    The algorithm is believed to be practically secure in the form of Triple DES, although there are theoretical attacks. This cipher has been superseded by the Advanced Encryption Standard (AES). DES has been withdrawn as a standard by the National Institute of Standards and Technology. [ 3 ]

    What is the difference between Des & DEA encryption algorithm?
    Some documents distinguish between the DES standard and its algorithm, referring to the algorithm as the DEA (Data Encryption Algorithm). The origins of DES date to 1972, when a National Bureau of Standards study of US government computer security identified a need for a government-wide standard for encrypting unclassified, sensitive information.

    What is the block size of Des?
    The block size is 64-bit. Though, key length is 64-bit, DES has an effective key length of 56 bits, since 8 of the 64 bits of the key are not used by the encryption algorithm (function as check bits only). General Structure of DES is depicted in the following illustration −

    What is simplified DES (SDES)?
    [ 50 ] Simplified DES (SDES) was designed for educational purposes only, to help students learn about modern cryptanalytic techniques. SDES has similar structure and properties to DES, but has been simplified to make it much easier to perform encryption and decryption by hand with pencil and paper.

    What is the difference between Des and Feistel cipher?
    DES is a special type of iterated cipher called a Feistel cipher because the encryption and decryption algorithm are almost the same. The only difference is that during decrypting are the round keys used in reverse order compared to encryption.
