Definition
  1. Noun:
    • The science or process of analyzing and deciphering codes, ciphers, and cryptograms: Cryptanalysis is the study of methods for obtaining the meaning of encrypted information without access to the secret key that is normally required for decryption.
Usage Examples
  • Noun:
    • Modern cryptanalysis requires a deep understanding of mathematics and computer science.
    • The intelligence agency employed a team of experts in cryptanalysis to break the enemy's coded messages.
    • Her thesis focused on the history of cryptanalysis during World War II.
Advanced Usage
  • "To perform cryptanalysis on something": To subject a code or cipher to analytical techniques.
    • The researchers performed cryptanalysis on the newly discovered encrypted manuscript.
  • "Resistant to cryptanalysis": Describing a cipher that is designed to be very difficult or impossible to break.
    • The new encryption algorithm is believed to be highly resistant to cryptanalysis.
Variants and Related Words
  • Cryptanalyst (n): A person who practices cryptanalysis.
    • Alan Turing was a brilliant cryptanalyst.
  • Cryptanalytic (adj): Relating to cryptanalysis.
    • The paper discussed various cryptanalytic techniques.
  • Cryptology (n): The broader study of codes and ciphers, encompassing both their creation (cryptography) and breaking (cryptanalysis).
    • Cryptology includes the twin fields of cryptography and cryptanalysis.
Synonyms
  • Codebreaking: The act or process of deciphering codes.
  • Cryptography (Note: This is often a complementary field, but in some contexts, it can be used loosely as a synonym for the entire field, which includes analysis).
Related Phrases
  • Cryptographic attack: A method used in cryptanalysis to find a weakness in a cryptographic system.
    • A brute-force attack is a basic type of cryptographic attack.
  • Ciphertext-only attack: A common scenario in cryptanalysis where the analyst has only the encrypted message to work with.
Noun
  1. the science of analyzing and deciphering codes and ciphers and cryptograms
