Record 1 2025-07-22

English

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

An analytical attack in which a cryptanalyst possesses only ciphertext.

CONT

When all that the attackers have to work with is the ciphertext, they have little to guide their efforts in guessing the key. Even a poorly designed cipher might be able to withstand such ciphertext-only attacks.

OBS

ciphertext-only attack: designation and definition standardized by ISO in collaboration with the International Electrotechnical Commission.

Key term(s)
  • cyphertext-only attack

French

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

Attaque analytique dans laquelle le cryptanalyste ne dispose que du cryptogramme.

OBS

attaque par cryptogramme : désignation et définition normalisées par l’ISO en collaboration avec la Commission électrotechnique internationale.

Spanish

Campo(s) temático(s)
  • Seguridad de IT
  • Criptografía y desciframiento
DEF

[...] análisis criptográfico donde el atacante sólo dispone de texto cifrado.

Record 2 2025-06-25

English

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

An attempt to break a code or to find a key using analytical methods.

OBS

Examples: A statistical analysis of patterns, a search for flaws in an encryption algorithm.

OBS

Contrast with exhaustive attack.

OBS

analytical attack; cryptanalytical attack: designations and definition standardized by ISO and the International Electrotechnical Commission.

French

Domaine(s)
  • Chiffrage et déchiffrage

OBS

Différent d’attaque exhaustive.

OBS

attaque analytique; attaque cryptanalytique : désignations et définition normalisées par l'ISO et la Commission électrotechnique internationale.

Spanish

Campo(s) temático(s)
  • Criptografía y desciframiento
  • Seguridad de IT

Record 3 2023-11-02

English

Subject field(s)
  • IT Security
DEF

An analytical attack in which a cryptanalyst possesses a substantial quantity of corresponding plaintext and ciphertext.

CONT

When the attackers know at least part of the plaintext menage, their chances for success increase significantly. To thwart such known-plaintext attacks, some cryptography systems electrically compress the message, squeezing out easily predictable patterns in plaintext, before encrypting it.

OBS

known-plaintext attack: designation and definition standardized by ISO and the International Electrotechnical Commission.

Key term(s)
  • known plaintext attack

French

Domaine(s)
  • Sécurité des TI
DEF

Attaque analytique dans laquelle le cryptanalyste dispose d’une quantité importante de texte en clair et du cryptogramme correspondant.

OBS

attaque par texte en clair connu : désignation et définition normalisées par l’ISO et la Commission électrotechnique internationale.

English

Subject field(s)
  • IT Security
DEF

An analytical attack in which a cryptanalyst can submit an unlimited number of plaintext messages and examine the corresponding ciphertext.

CONT

If an attacker steals a smart card containing crypto hardware, the thief can present billions of carefully chosen messages to the card and study the ciphertext output. Such chosen-plaintext attacks will crack a poorly designed cipher easily.
