Boomerang attack (original) (raw)
L'attaque boomerang est une version améliorée de la cryptanalyse différentielle, cette méthode a été inventée par David Wagner en 1999. Elle consiste à attaquer les deux moitiés d'un algorithme de chiffrement par bloc et part du principe que certaines propriétés, après perturbations des entrées, ne se propagent pas à travers toute la structure.

| dbo:abstract | In cryptography, the boomerang attack is a method for the cryptanalysis of block ciphers based on differential cryptanalysis. The attack was published in 1999 by David Wagner, who used it to break the COCONUT98 cipher. The boomerang attack has allowed new avenues of attack for many ciphers previously deemed safe from differential cryptanalysis. Refinements on the boomerang attack have been published: the amplified boomerang attack, and the rectangle attack. Due to the similarity of a Merkle–Damgård construction with a block cipher, this attack may also be applicable to certain hash functions such as MD5.
