English

Subject field(s)
  • Encryption and Decryption
  • Telecommunications Transmission
  • IT Security
DEF

A process that consists in reconstituting a set of data from its corresponding cryptogram by analyzing the inputs or outputs of the cryptographic system that was used or the system itself, rather than by resorting to the key that would normally be used.

OBS

cryptanalysis: term standardized by NATO.

Domaine(s)
  • Chiffrage et déchiffrage
  • Transmission (Télécommunications)
  • Sécurité des TI
DEF

Processus qui consiste à reconstituer un ensemble de données à partir du cryptogramme qui lui correspond en analysant les entrées ou les sorties du système cryptographique utilisé ou le système lui-même, plutôt qu'en recourant à la clé qui serait normalement employée.

OBS

analyse cryptographique : terme normalisé par l'OTAN.

OBS

cryptanalyse; décryptement : termes uniformisés par le Comité de terminologie française du Conseil de doctrine et de tactique de l'Armée de terre.

Record 3 2002-11-28

English

Subject field(s)
  • IT Security
  • Encryption and Decryption
DEF

A cryptanalysis method developed by Mitsuru Matsui (Mitsubishi), which searches for correlations between plaintext, ciphertext and the key that are true slightly more often than not, and then gathers statistics on large numbers of known plaintext-ciphertext pairs, looking for biases that will disclose clues about the key.

Record 4 1999-07-21

English

Subject field(s)
  • IT Security
DEF

A recently developed cryptanalysis method (Shamir and Eli Biham, TIT-Israel), in which many pairs of plaintext messages with carefully chosen differences are encrypted to find a corresponding pair of ciphertexts that have a certain dissimilarity. When such a pair is found, it reveals information about the key.

Subject field(s)
  • Electronic Warfare
  • Intelligence (Military)

À l'époque, les experts étaient unanimes à reconnaître que le DES était imperméable aux méthodes connues de cryptanalyse.
