It relies on two cryptographic techniques: substitution and transposition, which are carried out over 16 rounds.

WebDES has 16 round encryption round but AES has 10 rounds for 128 bit, 12 rounds for 192 bit, and 14 rounds for 256 bit. DES Works slower than AES. AES is more secure encryption than DES and is presently the international standard. DES is easily broken since it has known vulnerabilities. AES is built on the basis of a substitution-permutation ...
WebUsing weak keys, the outcome of the Permuted Choice 1 (PC-1) in the DES key schedule leads to round keys being either all zeros, all ones or alternating zero-one patterns. Since all the subkeys are identical, and DES is a Feistel network , the encryption function is self-inverting; that is, despite encrypting once giving a secure-looking cipher ...
