16/10/2013 Choosing between AES encryption and DES encryption to protect sensitive data is an important cybersecurity decision. Learn the difference between AES vs. DES encryption and which is the more 07/08/2010 AES vs TKIP: Que signifie AES? AES signifie Advanced Encryption Standard, oĂč il s'agit d'une collection de chiffres disponibles en taille de bloc de 128 bits et en longueurs de clĂ© d'environ 256, 192 ou 128 bits en fonction du matĂ©riel. Le standard AES est livrĂ© avec un protocole plus sĂ©curisĂ©, qui remplace l'hĂ©ritage apportĂ© par le protocole Data Encryption Standard (DES) publiĂ© dans les annĂ©es 1970. RĂ©sultat du match Licence AES 2 / Licence Ă©co-gestion 2. Match trĂšs serrĂ© entre les licences Ă©co-gestion et AES, et les deux formations font vĂ©ritablement jeu Ă©gal. Le choix se fera principalement en fonction de l'attrait pour les mathĂ©matiques, et la volontĂ© d'ĂȘtre encore encadrĂ© Ă l'universitĂ©.

AES uses a shared key which means that the same key (or a related key) is used to encrypted the data as is used to decrypt the data. For example if I encrypted an email using AES and I sent that email to you then you and I would both need to know the shared key used to encrypt and decrypt the email. This is different than algorithms that use a public key such PGP or SSL. If you wanted to put AES is the successor of DES as standard symmetric encryption algorithm for US federal organizations. AES uses keys of 128, 192 or 256 bits, although, 128 bit keys provide sufficient strength today. It uses 128 bit blocks, and is efficient in both software and hardware implementations. It was selected through an open competition involving hundreds of cryptographers during several years. DES is

Related: AES vs PGP Encryption: What is the Difference? Why AES replaced DES encryption. One of the original requirements from the National Institute of Standards and Technology (NIST) for the DES replacement algorithm was that it had to be efficient both in software and hardware implementations. (DES was originally practical only in hardware implementations.) Java and C reference The main difference between DES vs AES is the process of encrypting. In DES, the plaintext is divided into two halves before further processing whereas in AES whole block there is no division and the whole block is processed together to produce the ciphertext. AES is comparatively much faster than DES and is capable of encrypting large files in a fraction of seconds as compared to DES. Use AES. In more details: DES is the old "data encryption standard" from the seventies. Its key size is too short for proper security (56 effective bits; this can be brute-forced, as has been demonstrated more than ten years ago).Also, DES uses 64-bit blocks, which raises some potential issues when encrypting several gigabytes of data with the same key (a gigabyte is not that big nowadays).

DES vs AES. Le DES (Data Encryption Standard) est une mĂ©thode plutĂŽt ancienne de cryptage des donnĂ©es afin que les informations ne puissent pas ĂȘtre lues par d'autres personnes susceptibles d'intercepter le trafic. Le DES est assez vieux et a depuis Ă©tĂ© remplacĂ© par un AES (Advanced Encryption Standard) plus rĂ©cent et plus performant. Le remplacement a Ă©tĂ© effectuĂ© en raison des
AES comprend trois algorithmes de chiffrement par blocs : AES-128, AES-192 et AES-256. Chaque code chiffre et déchiffre les données par blocs de 128 bits au moyen de clés cryptographiques de 128, 192 et 256 bits, respectivement (Rijndael était conçu pour gérer encore d'autres tailles de bloc et longueurs de clé, mais la fonctionnalité n'a pas été adoptée dans AES).
